Normal elimination of urinary wastes is a basic function that most people take for granted. When the urinary system fails to function properly, eventually all organ systems are affected. Patients with alterations in urinary elimination often suffer emotionally from body image changes. It is important to know the reasons for urinary elimination problems, find acceptable solutions, and provide understanding and sensitivity to all patients’ needs.

Scientific Knowledge Base

Urinary elimination depends on the function of the kidneys, ureters, bladder, and urethra. Kidneys remove wastes from the blood to form urine. Ureters transport urine from the kidneys to the bladder. The bladder holds urine until the urge to urinate develops. Urine leaves the body through the urethra. All organs of the urinary system must be intact and functional for successful removal of urinary wastes. Intact efferent and afferent nerves from the bladder to the spinal cord and brain must be present (Fig. 45-1).

FIG. 45-1 Organs of urinary system.

Kidneys

The kidneys lie on either side of the vertebral column behind the peritoneum and against the deep muscles of the back. Normally the left kidney is higher than the right because of the anatomical position of the liver.

Kidneys filter waste products of metabolism that collect in the blood. The blood reaches each kidney by a renal (kidney) artery that branches from the abdominal aorta. Approximately 20% to 25% of the cardiac output circulates each minute through the kidneys. The nephron, the functional unit of the kidney, forms the urine. It is composed of the glomerulus, Bowman’s capsule, proximal convoluted tubule, loop of Henle, distal tubule, and collecting duct (Fig. 45-2).

FIG. 45-2 Renal nephron.

A cluster of blood vessels forms the capillary network of the glomerulus, which is the initial site of filtration of the blood and the beginning of urine formation. The glomerular capillaries permit filtration of water, glucose, amino acids, urea, creatinine, and major electrolytes into Bowman’s capsule. Large proteins and blood cells do not normally filter through the glomerulus. The presence of large proteins in the urine (proteinuria) is a sign of glomerular injury. The glomerulus filters approximately 125 mL of filtrate per minute.

Not all of the glomerular filtrate is excreted as urine. Approximately 99% is resorbed into the plasma, with the remaining 1% excreted as urine (Huether et al., 2008). The kidneys play a key role in fluid and electrolyte balance (see Chapter 41). Although output does depend on intake, the normal adult urine output averages 1200 to 1500 mL/day. An output of less than 30 mL/hr indicates possible circulatory, blood volume, or renal alterations.

The kidneys produce several substances vital to red blood cell (RBC) production, blood pressure, and bone mineralization. They are responsible for maintaining a normal RBC volume by producing erythropoietin. Erythropoietin functions within the bone marrow to stimulate RBC production and maturation and prolongs the life of mature RBCs (Huether et al., 2008). Patients with chronic kidney conditions cannot produce sufficient quantities of this hormone; therefore they are prone to anemia.

Renal hormones affect blood pressure regulation in several ways. In times of renal ischemia (decreased blood supply), renin is released from juxtaglomerular cells (Fig. 45-3). Renin functions as an enzyme to convert angiotensinogen (a substance synthesized by the liver) into angiotensin I. Angiotensin I is converted to angiotensin II in the lungs. Angiotensin II causes vasoconstriction and stimulates aldosterone release from the adrenal cortex. Aldosterone causes retention of water, which increases blood volume. The kidneys also produce prostaglandin E2 and prostacyclin, which help maintain renal blood flow through vasodilation. These mechanisms increase arterial blood pressure and renal blood flow (Huether et al., 2008).

FIG. 45-3 Physiological effects of renin-angiotensin mechanism.

The kidneys affect calcium and phosphate regulation by producing a substance that converts vitamin D into its active form. Patients with chronic alterations in kidney function do not make sufficient amounts of the active vitamin D. They are prone to develop renal bone disease resulting from the demineralization of bone caused by impaired calcium absorption.

Ureters

The ureters are tubular structures that enter the urinary bladder. Urine draining from the ureters to the bladder is usually sterile.

Peristaltic waves cause the urine to enter the bladder in spurts. The ureters enter obliquely through the posterior bladder wall. This arrangement prevents the reflux of urine from the bladder into the ureters during the act of micturition by the compression of the ureter at the ureterovesical junction (the juncture of the ureters with the bladder). An obstruction within a ureter such as a kidney stone (renal calculus) results in strong peristaltic waves that attempt to move the obstruction into the bladder. These waves result in pain often referred to as renal colic.

Bladder

The urinary bladder is a hollow, distensible, muscular organ (detrusor muscle) that stores and excretes urine. When empty, the bladder lies in the pelvic cavity behind the symphysis pubis. In men the bladder lies against the anterior wall of the rectum, and in women it rests against the anterior walls of the uterus and vagina.

The bladder expands as it becomes filled with urine. Pressure within it is usually low even when partly full, a factor that protects against infection. When the bladder is full, it expands and extends above the symphysis pubis. A greatly distended bladder may reach the level of the umbilicus. In a pregnant woman the developing fetus pushes against the bladder, reducing the capacity of the bladder and causing a feeling of fullness. This effect is more likely to occur in the first and third trimesters.

The trigone (a smooth triangular area on the inner surface of the bladder) is at the base of the bladder. An opening exists at each of the three angles of the trigone. Two are for the ureters, and one is for the urethra.

Urethra

Urine exits the bladder through the urethra and passes out of the body through the urethral meatus. Normally the turbulent flow of urine through the urethra washes it free of bacteria. Mucous membrane lines the urethra, and urethral glands secrete mucus into the urethral canal. Thick layers of smooth muscle surround the urethra. In addition, it descends through a layer of skeletal muscles called the pelvic floor muscles. When these muscles are contracted, it is possible to prevent urine flow through the urethra (Huether et al., 2008).

In women the urethra is approximately 4 to 6.5 cm (image to image inches) long. The external urethral sphincter, which is composed of skeletal muscle located about halfway down the urethra, permits voluntary flow of urine. However, the internal sphincter muscle is composed of smooth muscle and therefore is not under voluntary control. The short length of the urethra predisposes women and girls to infection. It is easy for bacteria to enter the urethra from the perineal area.

In men the urethra, which is both a urinary canal and a passageway for cells and secretions from reproductive organs, is about 20 cm (8 inches) long. The male urethra has three sections: prostatic, membranous, and penile.

Act of Urination

Several brain structures influence bladder function, including the cerebral cortex, thalamus, hypothalamus, and brainstem. Together they inhibit the urge to void or allow voiding. Normal voiding involves contraction of the bladder and coordinated relaxation of the urethral sphincter and pelvic floor muscles.

Bladder capacity varies with the individual but generally ranges from 600 to 1000 mL of urine (Lewis et al., 2011), and an adult normally voids every 2 to 4 hours. However, individuals are able to sense the desire to urinate when the bladder contains a smaller amount of urine (150 to 200 mL in an adult and 50 to 100 mL in a child). It is important to teach parents that children do not have enough neurological development to be toilet trained until after 24 months and some are not developed enough until 36 months. As the volume increases, the bladder walls stretch, sending sensory impulses to the micturition center in the sacral spinal cord. Impulses from the micturition center respond to or ignore this urge, thus making urination under voluntary control. If the person chooses not to void, the external urinary sphincter remains contracted, inhibiting the micturition reflex. However, when a person is ready to void, the external sphincter relaxes, the micturition reflex stimulates the detrusor muscle to contract, and efficient emptying of the bladder occurs. It is vital that nurses understand this process to be able to assess and determine which form of incontinence or bladder problem may be occurring.

Damage to the spinal cord above the sacral region causes reflex incontinence. This condition causes loss of voluntary control of urination; but the micturition reflex pathway often remains intact, allowing urination to occur without sensation of the need to void. If a chronic obstruction caused by neurological damage such as prostate enlargement hinders bladder emptying, over time the micturition reflex changes, causing bladder overactivity and possibly causing the bladder to not empty completely. Overflow incontinence occurs when a bladder is overly full and bladder pressure exceeds sphincter pressure, resulting in involuntary leakage of urine. Causes often include head injury; spinal injury; multiple sclerosis; diabetes; trauma to the urinary system; and postanesthesia sedatives/hypnotics, tricyclics, and analgesia (Lewis et al., 2011). Hyperreflexia, a life-threatening problem affecting heart rate and blood pressure, is caused by an overly full bladder. It is usually neurogenic in nature; however, it can be caused functionally by blockage.

Factors Influencing Urination

Many factors influence the volume and quality of urine and the patient’s ability to urinate. Some pathophysiological conditions are acute and reversible (urinary tract infection [UTI]), whereas others are chronic and irreversible (slow, progressive development of renal dysfunction). Sociocultural factors, psychological factors, fluid balance, and surgical and diagnostic procedures affect urine and urination in several ways. In addition, medications, including anesthesia, interfere with both the production and characteristics of urine, affect the act of urination, and affect the ability to completely empty or control voiding.

Disease Conditions: Disease processes that affect urine elimination affect renal function (changes in urine volume or quality), the act of urine elimination, or both. Conditions that affect urine volume and quality are generally categorized as prerenal, renal, or postrenal in origin.

Decreased blood flow to and through the kidney (prerenal), disease conditions of the renal tissue (renal) and obstruction in the lower urinary tract that prevents urine flow from the kidneys (postrenal) sometimes alter renal function. Conditions of the lower urinary tract, including narrowing of the urethra, altered innervation of the bladder, or weakened pelvic and/or perineal muscles, affect urinary elimination.

Diabetes mellitus and neuromuscular diseases such as multiple sclerosis cause changes in nerve functions that can lead to possible loss of bladder tone, reduced sensation of bladder fullness, or inability to inhibit bladder contractions. Older men often suffer from benign prostatic hyperplasia (BPH), which makes them prone to urinary retention and incontinence. Some patients with cognitive impairments, such as Alzheimer’s disease, lose the ability to sense a full bladder or are unable to recall the procedure for voiding. Diseases that slow or hinder physical activity interfere with the ability to void. Degenerative joint disease and Parkinsonism are examples of conditions that make it difficult to reach and use toilet facilities.

Diseases that cause irreversible damage to kidney tissue result in end-stage renal disease (ESRD). Eventually the patient has symptoms resulting from uremic syndrome. An increase in nitrogenous wastes in the blood, marked fluid and electrolyte abnormalities, nausea, vomiting, headache, coma, and convulsions characterize this syndrome. As the uremic symptoms worsen, aggressive treatment is indicated for survival (Box 45-1). These treatments are renal replacement therapies.

Box 45-1   Indications for Dialysis

• Renal failure that can no longer be controlled by conservative management (i.e., dietary modifications and administration of medications to correct electrolyte abnormalities)

• Worsening of uremic syndrome associated with ESRD (i.e., nausea, vomiting, neurological changes, pericarditis)

• Severe electrolyte and/or fluid abnormalities that cannot be controlled by simpler measures (e.g., hyperkalemia, pulmonary edema)

ESRD, End-stage renal disease.

Dialysis and organ transplantation are two methods of renal replacement. Dialysis takes one of two forms, peritoneal dialysis or hemodialysis. Patients can use both dialysis modalities for a short or long term, but they require specialized equipment and nurses with specialized education.

Peritoneal dialysis is an indirect method of cleaning the blood of waste products using osmosis and diffusion, with the peritoneum functioning as a semipermeable membrane. This method removes excess fluid and waste products from the bloodstream when a sterile electrolyte solution (dialysate) is instilled into the peritoneal cavity by gravity via a surgically placed catheter. The dialysate remains in the cavity for a prescribed time interval and then is drained out by gravity, taking accumulated wastes and excess fluid and electrolytes with it.

Hemodialysis requires a machine equipped with a semipermeable filtering membrane (artificial kidney) that removes accumulated waste products and excess fluids from the blood. In the dialysis machine dialysate fluid is pumped through one side of the filter membrane (artificial kidney) while a patient’s blood passes through the other side. The processes of diffusion, osmosis, and ultrafiltration clean the patient’s blood. Then the blood returns through a specially placed vascular access device (Gore-Tex graft, arteriovenous fistula, or hemodialysis catheter).

Organ transplantation is the replacement of a patient’s diseased kidney with a healthy one from a living or cadaver donor of compatible blood and tissue type. The new organ is surgically implanted into the abdomen. Special medications (immunosuppressives) are administered, often for life, to prevent the body from rejecting the transplanted organ. Unlike the other treatments, successful organ transplantation offers patients the potential for restoration of normal kidney function.

Sociocultural Factors: The degree of privacy needed for urination varies with cultural norms. North Americans expect toilet facilities to be private, whereas some European cultures accept communal toilet facilities. Social expectations (e.g., school recesses) influence the time of urination.

Psychological Factors: Anxiety and emotional stress cause a sense of urgency and increased frequency of urination. Anxiety often prevents a person from being able to urinate completely; as a result, the urge to void returns shortly after voiding. Emotional tension makes it difficult to relax abdominal and perineal muscles. Attempting to void in a public restroom sometimes results in a temporary inability to void. Privacy and adequate time to urinate are usually important to most people.

Fluid Balance: The kidneys primarily maintain the balance between retention and excretion of fluids (see Chapter 41). If fluids and the concentration of electrolytes and solutes are in equilibrium, an increase in fluid intake causes an increase in urine production. This amount varies with food and fluid intake. The volume of urine formed at night is about half of the volume formed during the day because both intake and metabolism decline. Nocturia (awakening to void one or more times at night) is often a sign of renal alteration. In a healthy person the intake of water in food and fluids balances the output of water in urine, feces, and insensible losses in perspiration and respiration. An excessive output of urine is polyuria. A urine output that is decreased despite normal intake is called oliguria. Oliguria often occurs when fluid loss through other means (e.g., perspiration, diarrhea, or vomiting) increases. It also occurs in early kidney disease. Often in severe kidney disease no urine is produced (anuria).

Ingestion of certain fluids directly affects urine production and excretion. Coffee, tea, cocoa, and cola drinks that contain caffeine promote increased urine formation (diuresis). Alcohol inhibits the release of antidiuretic hormone (ADH), also resulting in increased water loss in urine.

Febrile conditions affect urine production. A patient with excessive perspiration loses a large amount of fluids through insensible water loss, which decreases urine production. Fever causes an increase in body metabolism and accumulation of body wastes. Although urine volume is reduced, it is highly concentrated.

Surgical Procedures: The stress of surgery initially triggers the general adaptation syndrome (see Chapter 37). Preoperative orders of nothing-by-mouth or an underlying disease condition affect fluid balance before surgery, which reduces urine output. In addition, the stress response releases an increased amount of ADH, which increases water resorption. Stress also elevates the level of aldosterone, causing retention of sodium and water. Both of these substances reduce urine output in an effort to maintain circulatory fluid volume.

Anesthetics and narcotic analgesics slow the glomerular filtration rate, reducing urine output. These pharmacological agents also impair sensory and motor impulses traveling among the bladder, spinal cord, and brain. Patients are often unable to sense bladder fullness and initiate or inhibit micturition. Spinal anesthetics, in particular, create the risk of urinary retention because of an inability to sense the need to void and a possible inability of the bladder muscles and urethral sphincters to respond (Lewis et al., 2011).

Surgery of lower abdominal and pelvic structures sometimes impairs urination because of local trauma to surrounding tissues. After returning from surgery involving the ureters, bladder, and urethra, patients routinely have urinary catheters.

Medications: Many medications directly or indirectly contribute to urinary dysfunction. Antipsychotics, antidepressants, alpha-adrenergic agonists, and calcium channel blockers can cause urinary retention and overflow incontinence. Alpha-antagonists, diuretics, sedative hypnotics, opioid analgesics, angiotensin-converting enzyme (ACE) inhibitors, and antihistamines can cause urinary incontinence. Antiparkinson medications may cause urinary urgency and subsequent incontinence. Always consider these medications as the cause of new-onset urinary incontinence, especially in older adults.

Some medications change the color of urine. For example, phenazopyridine (Pyridium) colors the urine a bright orange to rust; amitriptyline causes a green or blue discoloration, whereas levodopa discolors the urine to brown or black. Cancer chemotherapy drugs also color the urine and are often toxic to the bladder and/or kidneys. Patients with impaired kidney function require dosage adjustments in medications excreted by the kidneys.

Diagnostic Examination: Examination of the urinary system influences micturition. Some procedures such as an intravenous pyelogram (IVP) require patients to limit fluids before the test. A restriction in fluid intake commonly lowers urine output. Diagnostic examinations (e.g., cystoscopy) involving direct visualization of urinary structures cause localized edema of the urethral passageway and spasm of the bladder sphincter. After the procedure, a patient may have difficulty voiding or have red or pink urine because of trauma to the urethral or bladder mucosa.

Alterations in Urinary Elimination

Most patients with urinary problems are unable to store urine or fully empty the bladder. These disturbances result from impaired bladder function, obstruction to urine outflow, or inability to voluntarily control micturition.

Some patients may have permanent or temporary changes in the normal pathway of urinary excretion. The surgical formation of a urinary diversion temporarily or permanently bypasses the bladder and urethra as the exit routes for urine. Permanent urinary diversions are often necessary in the patient with cancer of the bladder. The patient with a urinary diversion has a stoma (artificial opening) on the abdomen to drain urine. He or she has many special needs because urine drains to the outside through a stoma.

Urinary Retention: Urinary retention is an accumulation of urine resulting from an inability of the bladder to empty properly. Normally urine production slowly fills the bladder and prevents activation of stretch receptors until it distends to a certain level of stretch. The micturition reflex occurs, and the bladder empties. In urinary retention the bladder is unable to respond to the micturition reflex and thus is unable to empty. Urine continues to collect in the bladder, stretching its walls and causing feelings of pressure, discomfort, tenderness over the symphysis pubis, restlessness, and diaphoresis (sweating).

As retention progresses, retention with overflow develops. Pressure in the bladder builds to a point at which the external urethral sphincter is unable to hold back urine. The sphincter temporarily opens to allow a small volume of urine (25 to 60 mL) to escape. As urine exits, the bladder pressure falls enough to allow the sphincter to regain control and close. With retention a patient may void small amounts of urine 2 or 3 times an hour with no real relief of discomfort or may continually dribble urine. Be aware of the volume and frequency of voiding to assess for urinary retention. Assess the abdomen for evidence of bladder distention and tenderness.

In acute retention key signs are bladder distention and absence of urine output over several hours. A patient under the influence of anesthetics or analgesics often feels only pressure, but the alert patient has severe pain as the bladder distends beyond its normal capacity. In severe urinary retention the bladder holds as much as 2000 to 3000 mL of urine. Retention occurs as a result of urethral obstruction, surgical or childbirth trauma, and alterations in motor and sensory innervation of the bladder such as occurs with neuropathy secondary to diabetes. It may occur after removal of an indwelling catheter. Medication side effects or anxiety may also result in urinary retention. If a patient cannot void or completely empty the bladder, he or she must be catheterized because a UTI, kidney stones, and hyperreflexia can occur.

Retained or residual urine, also referred to as postvoid residual (PVR), occurs if a patient has urinary retention or cannot empty the bladder completely. You can use a portable noninvasive bladder ultrasound device (bladder scanner) or the technique of straight/intermittent catheterization to assess for PVR. Bladder scanners are often not readily available for nurses to use in all clinical settings, and straight/intermittent catheterization may be the only means to determine bladder urine volume. Regardless of the method used to determine PVR, assess the amount of urine left in the bladder within 10 to 15 minutes after a patient voids (Altschuler and Diaz, 2006). Instruct the patient not to void again before measurement. At least two residuals should be obtained since a patient may empty well one time and not the next. Spastic bladders and some medications and problems such as using a bedpan or not sitting upright to void cause inconsistent emptying. In normal micturition or in a normal void the bladder should empty completely.

Urinary Tract Infections: UTI is the most common health care–acquired infection; 80% of these infections result from the use of an indwelling urethral catheter (Lo et al., 2009). Catheterization results in over 1 million UTIs each year in the United States (Matteucci and Walsh, 2011). Infection frequently occurs after placement of urinary catheters, and each day a catheter is in place there is a 5% increase in bacteria in the urine (Saint et al., 2009). Catheter-associated UTIs (CAUTIs) are associated with increased hospitalizations, increased morbidity and mortality, longer hospital stay, and increased hospital costs (Newman, 2007). Each episode of CAUTI and ensuing complications are estimated to cost between $600 and $2800 (Saint et al., 2009). Because a CAUTI is common, costly, and believed to be reasonably preventable, as of October 1, 2008, the Centers for Medicare and Medicaid Services (CMS) chose it as one of the complications for which hospitals no longer receive additional payment to compensate for the extra cost of treatment (Saint et al., 2009). Consequently there has been a shift in reimbursement practices from its traditional focus on early recognition and prompt treatment to one of prevention (Wilson et al., 2009).

Although several different microorganisms cause CAUTIs, the patient’s own colonic flora, including Escherichia coli, remains the most common causative pathogen (Ksycki and Namias, 2009). Bacteriuria (bacteria in the urine) leads to the spread of organisms into the kidneys and possibly to bacteremia or urosepsis (bacteria in the bloodstream) (Lewis et al., 2011). Microorganisms commonly enter the urinary tract through the ascending urethral route. Bacteria inhabit the distal urethra and external genitalia in men and women and the vagina in women. Organisms enter the urethral meatus easily and travel up the inner mucosal lining to the bladder. Women are more susceptible to infection because of a short urethra and the proximity of the anus to the urethral meatus. In men prostatic secretions containing an antibacterial substance and the length of the urethra reduce the susceptibility to UTIs. However, men are at increased risk for infection-related renal disease. Older adults and patients with progressive underlying disease or decreased immunity are also at increased risk.

In a healthy person with good bladder function, organisms are flushed out during voiding. Residual (retained) urine in the bladder becomes more alkaline and is an ideal site for microorganism growth. Any condition resulting in urinary retention such as a kinked, obstructed, or clamped catheter increases the risk of a UTI.

Poor perineal hygiene is another cause of UTIs in women. Inadequate handwashing, failure to wipe from front to back after voiding or defecating, and frequent sexual intercourse predispose women to infection.

Patients with lower UTIs have pain or burning during urination (dysuria) as urine flows over inflamed tissues. Fever, chills, nausea, vomiting, and malaise develop as an infection worsens. An irritated bladder (cystitis) causes a frequent and urgent sensation of the need to void. Irritation to bladder and urethral mucosa results in blood-tinged urine (hematuria). The urine appears concentrated and cloudy because of the presence of white blood cells (WBCs) or bacteria. If infection spreads to the upper urinary tract (kidneys—pyelonephritis), flank pain, tenderness, fever, and chills are common.

Another common cause of infection is the introduction of instruments into the urinary tract. For example, the introduction of a catheter through the urethra provides a direct route for microorganisms (Nazarko, 2008). With an indwelling catheter bacteria ascend along the outside of the catheter on the urethral wall or travel up its lumen. Local irritation to the urethra or bladder predisposes tissues to bacterial invasion.

Urinary Incontinence: Urinary incontinence is the involuntary leakage of urine that is sufficient to be a problem. It can be either temporary or permanent, continuous or intermittent. Urinary incontinence related to urinary causes is called either stress or urge urinary incontinence (Palmer and Newman, 2007). Urge incontinence is more common in younger women and may be caused by local irritating factors such as UTIs (Ebersole et al., 2008). Individuals sense the urge to urinate but cannot keep from urinating long enough to reach a toilet. Stress incontinence occurs more often in older women when intraabdominal pressure exceeds urethral resistance. Muscles around the urethra become weak; thus even a small amount of urine may leak spontaneously (Ebersole et al., 2008). Some patients may have a mixed form of incontinence that has features of both stress and urge urinary incontinence. Table 45-5 on p. 1060 describes the types of urinary incontinence, their symptoms, and treatment interventions. Hyperactive or overactive bladder (OAB) is associated with individuals of all ages, but older adults are more likely to have incontinence associated with it following physical and cognitive decline associated with aging and effects of medications (Stewart, 2010). OAB results from sudden, involuntary contraction of the muscles of the urinary bladder, resulting in an urge to urinate (urge incontinence). Common abnormalities of the nervous system that cause OAB include cerebrovascular accident (CVA) and other head injuries, spinal cord injury, and diabetic neuropathy. Other causes include UTI and anxiety.

Approximately 15% to 30% of adult women experience urinary incontinence. It is present in as many as 30% to 70% of nursing home residents and in 30% of adults living at home (Touhy and Jett, 2010). Incontinence can impair body image and often leads to a loss of independence. Clothing becomes wet with urine, and the accompanying odor adds to the embarrassment. As a result, patients with this problem often avoid social activities. They often fail to discuss this condition with health care providers or nurses, and as a result urinary incontinence is underreported and undertreated. Resources for information about continence care, patient education, and treatment are available at the following websites: the Society for Urological Nurses and Associates (http://www.suna.org), the National Association for Continence (http://www.nafc.org), and the Simon Foundation (http://www.simonfoundation.org).

Physical limitations and environmental barriers are risks for incontinence. People with restricted mobility have greater chances of being incontinent because of their inability to reach toilet facilities in time. Low-set chairs and beds raised well above the floor are obstacles for people who must get up to reach a toilet. Some patients often lack the energy to walk very far at one time. The toilet is sometimes too far away for patients with urge incontinence. Patients who have difficulty undoing buttons or manipulating zippers face another obstacle.

Continued episodes of incontinence is a risk for impaired skin integrity. The character of urine changes when it remains in contact with skin, causing skin breakdown. The immobilized patient with frequent incontinence is especially at risk for pressure ulcers (see Chapter 48). Additional health care and patient education resources are available at the websites for the American Geriatrics Society (http://www.americangeriatrics.org) or the American Urogynecologic Society (http://www.augs.org).

Urinary Diversions: Conditions such as bladder cancer, radiation injury to the bladder, or chronic urinary infections may necessitate a urinary diversion to drain urine from a diseased or dysfunctional bladder. There are two types of continent urinary diversions (Fig. 45-4, A). One is a continent urinary reservoir that is created from a distal portion of the ileum and proximal portion of the colon. The ureters are embedded in the reservoir. This reservoir is situated under the abdominal wall and has a narrow ileal segment brought out through the abdominal wall to form a small stoma. The ileocecal valve creates a one-way valve in the pouch through which a catheter is inserted to empty the urine from the pouch. Patients must be willing and able to catheterize the pouch 4 to 6 times a day for the rest of their lives.

FIG. 45-4 Types of urinary diversions. A, Continent urinary reservoir. B, Urostomy (ileal conduit).

The second continent urinary diversion is an orthotopic neobladder that also uses an ileal pouch to replace the bladder. Anatomically the pouch is in the same position where the bladder was before removal, allowing patients to void normally.

Incontinent urinary diversions are less commonly performed. The surgery involves connecting the ureters to a section of the intestinal ileum with formation of a stoma on the abdominal wall (Fig. 45-4, B). Urine drains continuously because a patient has no sensation or control over urinary output, requiring the application of a collection pouch at all times.

Some patients need urinary drainage directly from one or both kidneys. In this case a tube is placed directly into the renal pelvis. This procedure is called a nephrostomy.

Any urinary diversion poses threats to a patient’s body image. The patient must learn how to manage the diversion, and those who do not have a continent urinary diversion must wear an artificial device at all times. However, most patients are able to wear normal clothing, engage in physical activity, travel, and have sexual relations. Care must be taken not to pull on tubing, especially in a nephrostomy, since it can be pulled out, causing tissue and organ damage and infection. Most nephrostomies are sutured into the kidney.

Refer patients with a urinary diversion to an ostomy nurse (a nurse with specialized education in this area). This specialist is a valuable resource for assisting a patient and family with matters pertaining to all aspects of care. The ostomy nurse often meets with the patient and family before surgery. In addition, refer the patient to the United Ostomy Associations of America (http://www.uoaa.org). This organization provides information about support groups to enhance coping and adaptation to lifestyle and body-image changes.

Nursing Knowledge Base

Urinary elimination is a basic function and is usually a private process. Many patients need physiological and psychological assistance from the nurse. Whether a patient has an actual or potential urinary problem, be sensitive to his or her elimination needs. You need knowledge of concepts beyond the anatomy and physiology of the urinary system to give appropriate care. In addition, you need to understand and apply knowledge about infection control principles.

Infection Control and Hygiene

The urinary tract is sterile. Use infection control principles to help prevent the development and spread of UTIs and treat existing infections. E. coli, a common bacteria found in feces, causes many CAUTIs. Infection can occur in any location of the urinary tract. Apply knowledge of medical and surgical asepsis when providing care involving the urinary tract or external genitalia (see Chapter 28). Any invasive procedure of the urinary tract such as catheterization requires sterile technique. Procedures such as perineal care or examination of the genitalia require medical asepsis, including proper hand hygiene. Use medical asepsis by wiping off tubing with antiseptic wipes when changing from a large-volume urinary bag to a small-volume leg bag.

Factors Influencing Urination

Factors in a patient’s history that normally affect urination are age, environmental factors, medication history, psychological factors, muscle tone, fluid balance, current surgical or diagnostic procedures, and presence of disease conditions. Be alert to individual needs related to normal changes of aging that predispose older adults to certain elimination problems (Box 45-2). Also assess the bowel elimination pattern because constipation often interferes with normal urine elimination (see Chapter 46). Problems with urination also stem from dehydration. Evaluate environmental barriers in the home or health care setting. Aids such as elevated toilet seats, grab bars, or a portable commode are often necessary to ensure patient safety.

Box 45-2   Focus on Older Adults

Promoting Urinary Health

• Facilitate more frequent opportunities to void. Older adults have a smaller bladder capacity than younger adults (Ebersole et al., 2008).

• Encourage older adults to empty bladder completely before and after meals and at bedtime (Touhy and Jett, 2010).

• Encourage patient to increase fluid intake to at least six to eight glasses a day unless medically contraindicated. Dilute urine discourages bacterial growth. Discourage drinking of coffee, tea, brown cola, and alcohol since these have a diuretic effect and increase urinary frequency (Touhy and Jett, 2010).

• Make fluids such as cranberry juice available as part of patient’s fluid intake. Cranberry juice and vitamin C help acidify the urine to decrease bacterial infections of the bladder (Ebersole et al., 2008).

• Restricting fluid intake does not decrease urinary incontinence severity or frequency (Touhy and Jett, 2010).

• Avoid routine use of indwelling catheters. If one is necessary, use it no longer than necessary. The risk of infection increases dramatically for catheterized patients (Fernandez and Griffiths, 2006).

• Note that incontinence is not a normal part of aging and make efforts to assess incontinence and provide interventions to promote return to continence (Touhy and Jett, 2010).

Growth and Development

Growth and development factors determine a patient’s ability to control the act of urination during the life span. Infants and young children cannot effectively concentrate urine. Their urine appears light yellow or clear. In relation to their small body size, infants and children excrete large volumes of urine. For example, a 6-month-old infant who weighs 13 to 18 pounds (6 to 8 kg) excretes 400 to 500 mL of urine daily.

The neurological system is not well developed until 2 to 3 years of age in a normal toddler. Until this age he or she is not able to associate the sensations of bladder filling and urination. A child must be able to recognize the feeling of bladder fullness, to hold urine for 1 to 2 hours, and to communicate the sense of urgency. Many toddlers are then able to control the external sphincter, and toilet training begins. Daytime control of urination is easier to accomplish than nighttime control and occurs earlier in the child’s development, usually by 2 to 3 years of age. Some children do not gain full control until age 4 or 5. Occasional daytime accidents or nocturnal enuresis (nighttime voiding without awakening) sometimes continue until age 5 (see Chapter 12).

During pregnancy urinary frequency is common, and susceptibility to UTI increases. Temporary or permanent changes resulting from repeated deliveries or hormonal changes often result in decreased perineal muscle tone, leading to urgency and stress incontinence.

Aging often impairs micturition. In men prostate enlargement usually begins during the 40s and continues throughout life, resulting in urinary frequency and possible urinary retention. In women changes in the urethral mucosa associated with loss of estrogen during and after menopause contribute to increased susceptibility to UTIs (Palmer and Newman, 2007).

Changes in kidney and bladder function also occur with aging. The ability of the kidney to concentrate urine declines. The older adult often experiences nocturia. The bladder loses muscle tone, and capacity decreases, resulting in increased urinary frequency. Because the bladder cannot contract effectively, an older adult often retains urine in it after voiding. These changes increase the risk for bacterial growth and development of UTIs.

Muscle Tone

Weak abdominal and pelvic floor muscles impair the ability of the urinary sphincter to maintain tone during increased abdominal pressure. Poor control of micturition or incontinence results from muscle wasting caused by prolonged immobility, muscle damage during vaginal childbirth, being overweight, caffeine use because caffeine relaxes the smooth muscle of the sphincter, muscle atrophy secondary to menopause, or other traumatic damage to pelvic nerves and muscles.

Critical Thinking

Successful critical thinking requires synthesis of knowledge, experience, information gathered from patients, critical thinking attitudes, and intellectual and professional standards. Clinical judgments require you to collect necessary information, analyze the data, and anticipate and make decisions regarding patient care.

During assessment consider all elements that build toward making appropriate nursing diagnoses. In the case of urinary elimination, integrate knowledge from nursing and other disciplines, previous experiences, and information gathered from patients to understand the process of urinary elimination and the impact on a patient and family. As a result, you are able to identify the unique impact of these problems on patients and families.

In addition, use critical thinking attitudes such as perseverance to find a plan of care to provide successful management of urinary elimination problems. Professional standards provide valuable directions for management. You are in a key position to serve as a patient advocate by suggesting noninvasive alternatives to catheterization use (e.g., the use of a bladder scanner to evaluate urine volume without invasive instrumentation or implementation of a voiding schedule for the incontinent patient).

When planning and implementing care for the patient with alterations in urinary elimination, also use standards developed by professional organizations such as the American Nurses Association (ANA), the International Continence Society (ICS), and the United Ostomy Associations of America as a guide for individualized patient care.

Nursing Process

Apply the nursing process and use a critical thinking approach in the care of patients. The nursing process provides a clinical decision-making approach for you to develop and implement an individualized plan of care.

Assessment

During the assessment process, thoroughly assess each patient and critically analyze findings to ensure that you make patient-centered clinical decisions required for safe nursing care.

Through the Patient’s Eyes

Throughout the assessment process it is important to consider the patient’s frame of reference of his or her illness experience. Also consider whether the patient understands his or her health status along with his or her self-care ability. Value the patient’s expertise with his or her own health and symptoms. Consider the patient’s cognitive ability to understand the signs and symptoms of the illness. Remember that you are in partnership with the patient or designated surrogates in planning, implementing, and evaluating care. Always ask what he or she expects from care. Does the patient expect that the UTI will be resolved?

Make sure that your approach to a patient’s elimination needs considers personal, social, and gender habits. Be sensitive and ask questions in a straightforward manner. Gender influences positioning for urination: males stand, whereas females sit. Place patients in a position of comfort. Some men who cannot stand to urinate become overly distressed. Gender differences also affect risk factors associated with urinary alterations. If a patient prefers privacy, try to prevent interruptions as he or she voids. Treat all patients with understanding and acceptance.

Be aware of your own attitudes and values about working with patients from diverse ethnic, social, and cultural backgrounds. Know that culture influences the choice of appropriate nursing interventions. In some cultures the embarrassment related to urinary elimination problems is so great that many patients, especially women, refuse to seek treatment. In some cultures patients prefer to squat over a receptacle rather than sit on one. Culture dictates when and where it is appropriate to urinate. It also determines whether it is proper for a male to care for the urinary needs of a female or if gender-congruent care is needed (see Chapter 9).

Identifying Urinary Alterations

To identify a urinary elimination problem and gather data for a care plan, use scientific and nursing knowledge, conduct a nursing history, perform a physical assessment, assess the patient’s urine, and review information from diagnostic tests and examinations. Use critical thinking to synthesize this information as assessment proceeds (Fig. 45-5). Adequate assessment results in the formulation of nursing diagnoses appropriate for alterations in urinary elimination. When assessing for problems with urinary elimination, be aware of the impact of the patient’s culture and language in the assessment process (Box 45-3).

Box 45-3   image Cultural Aspects of Care

Urinary Elimination

Urine elimination is a personal, private activity that individuals do not share with others. When patients have needs related to urine elimination, be aware of the intrusive nature of intervention. Because of the embarrassing nature of urinary problems such as incontinence, many women do not report symptoms (Beji et al., 2010; Gemmill and Wells, 2010). In addition, other characteristics such as a patient’s culture also affect care. Although you cannot be knowledgeable about the impact of every culture on patient care, it is important to be open to and respect practices different from your own.

Implications for Practice

• When English is a second language, use simple and clear sentences in communicating with patients. Remember, speaking louder or more slowly does not always help. Learn at least a few important words in the patient’s language to allow for future interchanges. In some situations an interpreter is needed (Giger and Davidhizar, 2008).

• If available, provide written materials in patient’s primary language. If not, provide the English version. Some patients are able to read better than they understand the spoken word. Time to review the information also increases understanding.

• In some cultures intimate contact or discussion of urinary problems between genders is forbidden outside marriage. Urological care, whether involving questions, discussion, or contact, is usually considered intimate care. Gender-congruent caregivers are assigned to a patient from these cultures (e.g., Muslim) (Beji et al., 2010; Giger and Davidhizar, 2010).

• Cultures view disease differently. It is important to understand how the culture views the cause and treatment of the condition and how traditional Western medicine may or may not fit with that understanding. Programs to help with urinary problems need to be adapted to the cultural values of the woman seeking assistance (Bradway et al., 2010).

• Cultures allow for varied involvement of family in a patient’s care. This source of strength is important to the health of the patient, and family must be included in the plan of care (Giger and Davidhizar, 2008).

• Cultural influences may affect the willingness of a patient to seek care. Be aware of topics that specific cultures may find offensive, which can make discussion of nursing interventions difficult (Giger and Davidhizar, 2008).

Nursing History

The nursing history includes a review of a patient’s elimination patterns and symptoms of urinary alterations and an assessment of other factors that possibly affect the ability to urinate normally. Use questions to help direct the patient to focus on specific urinary problems (Box 45-4).

Box 45-4   Nursing Assessment Questions

Nature of the Problem

• What type of problems are you having with urination?

• Describe a recent day and or night when you were having urinary problems.

• Has this pattern remained constant, or do you have different patterns on different days or nights?

Signs and Symptoms

• Do you have urgency (i.e., feeling as though you have to void immediately)?

• Do you ever lose urine when you cough or sneeze?

• Does leakage occur at other times?

Onset and Duration

• When did you first notice a problem?

• How long has this problem lasted?

Severity

• How many times a day or night do you void or have leakage?

• How does this pattern compare with the pattern you last remember?

• What do you do when the symptoms occur?

Predisposing Factors

• Have you ever had a vaginal birth? More than once?

• Do you notice what you are doing at the time of urinary incidents?

• Do your symptoms increase after eating or drinking food with caffeine or alcohol?

• Which medications do you take routinely, and have any recently changed?

• Do you have a physical illness that may interfere with your usual urinary pattern?

Effect on Patient

• How have these symptoms affected your life?

• Have you had to change any of your usual activities?

• Have you sought any health care assistance with this problem?

Pattern of Urination: Ask the patient about daily voiding patterns, including frequency and times of day, normal volume at each voiding, and any recent changes. Frequency varies among individuals and with intake and other types of fluid losses. The common times for urination are on awakening, after meals, and before bedtime. Most people void an average of 5 or more times a day. Some patients who void frequently during the night may have renal disease, prostate enlargement, or cardiac disease. Information about the pattern of urination establishes a baseline for comparison.

Symptoms of Urinary Alterations: Certain symptoms specific to urinary alterations may occur in more than one type of disorder. During assessment ask the patient about any symptoms related to urination (Table 45-1). Also assess whether the patient is aware of conditions or factors that precipitate or aggravate symptoms and determine what the patient does when any of these symptoms occur.

TABLE 45-1

Common Types of Urinary Alterations

SYMPTOMS DESCRIPTIONS CAUSES OR ASSOCIATED FACTORS
Urgency Feeling of need to void immediately Full bladder, bladder irritation or inflammation from infection, overactive bladder, psychological stress
Dysuria Painful or difficult urination Bladder inflammation, trauma or inflammation of urethral sphincter
Frequency Voiding at frequent intervals (less than 2 hours) Increased fluid intake, bladder inflammation, increased pressure on bladder (pregnancy), diuretic therapy
Hesitancy Difficulty initiating urination Prostate enlargement, anxiety, urethral edema
Polyuria Voiding large amounts of urine Excess fluid intake, diabetes mellitus or insipidus, use of diuretics, postobstructive diuresis
Oliguria Diminished urinary output relative to intake (usually 400 mL/24 hr) Dehydration, renal failure, UTI, increased ADH secretion, heart failure
Nocturia Voiding one or more times at night Excessive fluid intake before bed (especially coffee or alcohol), renal disease, aging process, prostate enlargement
Dribbling Leakage of urine despite voluntary control of urination Stress incontinence, overflow from urinary retention (e.g., from BPH)
Incontinence Involuntary loss of urine Multiple factors: Unstable urethra, loss of pelvic muscle tone, fecal impaction, neurological impairment, overactive bladder
Hematuria Blood in urine Neoplasms of kidney or bladder, glomerular disease, infection of kidney or bladder, trauma to urinary structures, calculi, bleeding disorders
Retention Accumulation of urine in bladder, with inability of bladder to empty fully Urethral obstruction (stricture), decreased sensory activity, neurogenic bladder, prostate enlargement, postanesthesia effects, side effects of medications (e.g., anticholinergics, opioids)
Residual urine Volume of urine remaining after voiding (≥100 mL) Inflammation or irritation of bladder mucosa from infection, neurogenic bladder, prostate enlargement, trauma, or inflammation of urethra

ADH, Antidiuretic hormone; BPH, benign prostatic hyperplasia; UTI, urinary tract infection.

Note the presence of an indwelling catheter. It places a patient at risk for infection, catheter blockage, or skin-care problems. Monitor fluid balance through regular intake and output (I&O) measurements (see Chapter 41). Patients with a urinary diversion sometimes need special assistance to maintain adequate urine elimination and skin care integrity.

Physical Assessment

A physical examination (see Chapter 30) provides you with data to determine the presence and severity of urinary elimination problems. The primary structures to assess include the skin and mucosal membranes, kidneys, bladder, and urethral meatus. Fluid intake and the pattern and amounts, which are objective data, are important to assess (see Chapter 41).

Skin and Mucosal Membranes: Observe the condition of the skin and mucosal membranes. Problems with urinary elimination are frequently associated with fluid and electrolyte disturbances. By assessing skin turgor and the oral mucosa you gather data about the patient’s hydration status. Urinary incontinence increases the risk for skin breakdown. Observe the perineum for rashes, blistering, irritation, and breakdown.

Kidneys: Nurses with advanced examination skills learn to palpate the kidneys during abdominal examination. The position, shape, and size of the kidneys reveal problems such as tumors; whereas tenderness indicates inflammation. Auscultation is sometimes performed to detect the presence of a renal artery bruit (sound resulting from turbulent blood flow through a narrowed artery).

Bladder: In adults the bladder rests below the symphysis pubis. When it is distended, it rises above the symphysis pubis at the midline of the abdomen and often extends to just below the umbilicus. On inspection you may note a swelling or convex curvature of the lower abdomen. Gently palpate the lower abdomen. The partially filled bladder normally feels smooth and rounded. Gentle palpation on a distended bladder causes the patient to feel the urge to urinate, tenderness, or even pain. Percussion of a full bladder yields a dull percussion note.

Urethral Meatus: Observe the urinary meatus for any discharge, inflammation, and lesions. To examine the female, a dorsal recumbent position provides full exposure of the genitalia. While wearing clean gloves, retract the labial folds to see the urethral meatus. Normally it is pink, it appears as a small slitlike opening below the clitoris and above the vaginal orifice, and there is no discharge; if discharge is present, obtain specimens of urethral discharge before the patient voids.

Women with vaginal infections are susceptible to UTIs because it is easy for the drainage to travel to the urethral meatus. If yeast (candidiasis) is found in urine, it is important to inspect the vagina, in the groin area, under the breasts, and in the mouth for the source. It needs to be treated to keep UTI from yeast recurring. Older women may have vaginitis as a result of estrogen deficiency. Inspect the vaginal orifice carefully for signs of inflammation and describe any drainage.

A man’s urethral meatus is normally a small opening at the tip of the penis. Inspect the meatus for discharge, inflammation, and lesions. It is necessary to retract the foreskin in uncircumcised men to see the meatus. Wear clean gloves when retracting the foreskin. Be sure to replace it after the examination is complete to prevent swelling of the tissue around the glans of the penis.

Assessment of Urine

Assessment of urine involves measuring patients’ fluid I&O and observing characteristics of their urine.

Intake and Output: Assess the patient’s average daily fluid intake. If you need an accurate measurement of fluid intake from the patient who is at home, ask him or her to estimate his or her intake by showing a measurement on a commonly used glass or cup.

In a health care setting measure a patient’s fluid intake either when the health care provider orders I&O measurements or when you judge that measurement is needed (see Chapter 41). A change in urine volume is a significant indicator of fluid alterations or kidney disease. While caring for the patient, use a graduated receptacle to measure urinary output from a bedpan or urinal after each voiding. Special receptacles (urimeters) that attach between indwelling catheters and drainage bags are a convenient means of accurately measuring urine volume. A urimeter holds 100 to 200 mL of urine. After measuring urine from a urimeter, drain the cylinder into the urinary drainage bag or into a receptacle for disposal. Use urimeters when precise hourly measurements of urine are necessary.

When you measure urine from a drainage bag, the use of a separate plastic graduated measuring receptacle obtains a more precise measurement of urine output (Fig. 45-6). Each patient needs to have a graduated receptacle for his or her exclusive use to prevent potential cross-contamination. Label each container with patient name. The container needs to be rinsed after emptying, and the tubing that drains the bag securely clamped and cleaned with alcohol before putting it back in the holder.

image

FIG. 45-6 Urine drainage bag.

Report any extreme increase or decrease in urine volume. An individual’s daily output generally ranges from 1200 to 1500 mL of urine (Hall, 2011). An hourly output of less than 30 mL for more than 2 consecutive hours is cause for concern. Similarly, you need to report consistently high volumes of urine (polyuria) (i.e., over 2000 to 2500 mL daily).

Characteristics of Urine: Inspect the patient’s urine for color, clarity, and odor.

Color: Normal urine ranges from a pale, straw color to amber, depending on its concentration. Urine is usually more concentrated in the morning or with fluid volume deficits. As a person drinks more fluids, urine becomes less concentrated.

Bleeding from the kidneys or ureters causes dark red urine; bleeding from the bladder or urethra causes bright red urine. Various medications and foods also change urine color. For example, phenazopyridine, a urinary analgesic, colors urine bright orange. Eating beets, rhubarb, or blackberries causes red urine. Special dyes used in intravenous diagnostic studies eventually discolor urine. Dark amber urine is the result of high concentrations of bilirubin caused by liver dysfunction. Document and report any abnormal color or sediment, especially if the cause is unknown.

Clarity: Normal urine appears transparent at voiding. Urine that stands in a container becomes cloudy. Freshly voided urine in patients with renal disease appears cloudy or foamy because of high protein concentrations. Urine may also appear thick and cloudy as a result of bacteria and WBCs.

Odor: Urine has a characteristic odor. The more concentrated the urine, the stronger the odor. Stagnant urine has an ammonia odor, which is common in patients who are repeatedly incontinent. A sweet or fruity odor occurs from acetone or acetoacetic acid (by-products of incomplete fat metabolism) seen with diabetes mellitus or starvation. Some food and medications can affect the odor of urine (e.g., asparagus and amoxicillin). A foul odor is often associated with a possible infection.

Urine Testing: Nurses often collect urine specimens for laboratory testing. The type of test determines the method of collection. Label all specimens with the patient’s name, date, and time of collection. Transport specimens to the laboratory in a timely fashion to ensure accuracy of test results. Agency infection control policies require the adherence to standard precautions by all personnel during specimen handling (see Chapter 34).

Specimen Collection: The nurse collects random, clean-voided or midstream, sterile, and timed specimens (Table 45-2). The method of collection varies based on a patient’s developmental level and the type of specimen ordered.

TABLE 45-2

Urine Testing

COLLECTION TYPE/USE OF SPECIMEN NURSING CONSIDERATIONS
Random (routine urinalysis) Collect during normal voiding or from an indwelling catheter or urinary diversion collection bag. Do not collect from an indwelling catheter drainage bag.
Use a clean specimen cup.
Clean-voided or midstream (culture and sensitivity) See Skill 45-1 on pp. 1068-1070.
Use a sterile specimen cup.
Sterile specimen (culture and sensitivity) If the patient has an indwelling catheter, collect a sterile specimen by using aseptic technique through the special sampling port (Fig. 45-7) found on the side of the catheter.
  Clamp the tubing below the port, allowing fresh, uncontaminated urine to collect in the tube. After wiping the port with an antimicrobial swab, insert a sterile syringe hub and withdraw at least 3 to 5 mL of urine (check agency policy).
  Using sterile aseptic technique, transfer the urine to a sterile container (see Chapter 28).
Timed urine specimens (for measuring levels of adrenocortical steroids or hormones, creatinine clearance, or protein quantity tests) Time required may be 2-, 12-, or 24-hour collections. The timed period begins after the patient urinates and ends with a final voiding at the end of the time period. The patient voids into a clean receptacle, and the urine is transferred to the special collection container, which often contains special preservatives. Each specimen must be free of feces and toilet tissue. Missed specimens make the whole collection inaccurate. Check with agency policy and the laboratory for specific instructions.

FIG. 45-7 Urine specimen collection: aspiration from a collection port in drainage tubing of indwelling catheter (needleless technique).

Urine Collection in Children: Specimen collection from infants and children is often difficult. Adolescents and school-age children are usually able to cooperate, although some are embarrassed. Preschool children and toddlers have difficulty voiding on request. It often helps to offer the child fluids 30 minutes before requesting a specimen. You need to use terms for urination that the child is able understand. A young child is often reluctant to void in unfamiliar receptacles. A potty chair or specimen hat placed under the toilet seat is usually effective. You will need to use special collection devices for infants or toddlers who are not toilet trained. You can attach clear plastic, single-use bags with self-adhering material over the child’s urethral meatus. Do not obtain specimens by squeezing urine from the diaper because the results will be inaccurate.

Common Urine Tests:

Urinalysis: The laboratory performs a urinalysis on a specimen obtained by any of the previously described methods. Table 45-3 lists normal values for a urinalysis. A lab examines specimens as soon as possible, preferably within 2 hours. Make sure that it is the first voided specimen in the morning to ensure a uniform concentration of constituents. For a quick screening perform certain portions of the urinalysis with special reagent strips. Dip the strips into the urine and observe for a color change in the time interval designated on the package (Fig. 45-8).

FIG. 45-8 Checking results of chemical reagent strip dipped in urine.

Specific Gravity: The specific gravity is the weight or degree of concentration of a substance compared with an equal volume of water. Pour a urine specimen into a special clean, dry cylinder. The weighted urinometer is suspended in the cylinder of urine. The concentration of dissolved substances in the urine aids in determination of a patient’s fluid balance. This measurement is always part of a complete urinalysis. Nurses in critical care units are often responsible for doing periodic measurements of urine specific gravity (see Table 45-3).

If questions regarding the accuracy of specific gravity measurements arise, obtain a urine osmolality test. Although both tests measure urine concentration, the osmolality test is more accurate because it measures the total number of particles in a solution (see Chapter 41).

Urine Culture: A urine culture requires a sterile or clean-voided sample of urine. It takes approximately 24 to 48 hours before the laboratory can report findings of bacterial growth. While awaiting results, a broad-spectrum antibiotic is sometimes ordered as soon as a culture has been obtained. The test for sensitivity determines which specific antibiotics are effective. The results (sensitivities) of a urine culture may show that another antibiotic would be more effective. In this case a new antibiotic is ordered.

Diagnostic Examinations

The urinary system is one of the few organ systems amenable to accurate diagnostic study by several radiographic techniques. The two approaches for visualization of urinary structures, direct and indirect techniques, are either quite simple or very complex, requiring extensive nursing intervention. These procedures are further subdivided into invasive or noninvasive categories (Table 45-4).

TABLE 45-4

Diagnostic Examinations

Many of the nursing responsibilities related to diagnostic examinations of the urinary tract are common to many of the studies. The common responsibilities before the study include the following:

• Obtain a signed consent (check agency policy)

• Assess patient for history of any allergies and whether they have had a previous reaction to a contrast agent (Schabelman and Witting, 2010). Allergic individuals in general (including individuals with asthma) are at mildly increased risk for developing adverse reactions to radiocontrast media (Beaty, Lieberman, and Slavin, 2008).

• Administer bowel-cleaning medications as ordered (check agency policy)

• Ensure that patient receives appropriate pretest diet (clear liquids) or nothing by mouth (NPO) as needed

The common responsibilities following the study include the following:

• Assessing I&O

• Observing characteristics of urine (color, clarity, presence of blood)

• Encouraging fluid intake, especially if using radiopaque dye

Nursing Diagnosis

A thorough assessment of a patient’s urinary elimination function reveals patterns of data that allow a nurse to make relevant and accurate nursing diagnoses. Use critical thinking to reflect on knowledge of previous patients, apply knowledge of urinary function and the effects of disorders, review defining characteristics, and make a specific nursing diagnosis. Data from questions about the urinary system are important in identifying nursing diagnoses. The diagnosis focuses on a specific urinary elimination alteration or an associated problem such as impaired skin integrity related to urinary incontinence. Identification of defining characteristics leads to selection of an appropriate diagnosis. An important part of formulating nursing diagnoses is identifying the relevant causative or related factor. You choose interventions that treat or modify the related factor for the diagnosis to be resolved. Specifying related factors for each diagnosis allows selection of individualized nursing interventions (Ackley and Ladwig, 2011). For example, impaired skin integrity related to incontinence requires interventions such as a toileting schedule or assisting the patient to the toilet at frequent intervals. In contrast, impaired skin integrity related to inability to change positions requires interventions such as placing the patient on a turning schedule. Box 45-5 provides an example of diagnostic reasoning. Some nursing diagnoses common to patients with urine elimination alterations include the following:

Box 45-5   Nursing Diagnostic Process

Stress Urinary Incontinence Related to Weakened Pelvic Musculature

image

• Social isolation

• Disturbed body image

• Urinary incontinence (functional, stress, urge, overflow)

• Pain (acute, chronic)

• Risk for infection

• Toileting self-care deficit

• Impaired skin integrity

• Impaired urinary elimination

• Constipation

• Urinary retention

Planning

During planning integrate the knowledge from assessment and information about available resources and therapies to develop an individualized plan of care (see the Nursing Care Plan). Match the patient’s needs with clinical and professional standards recommended in the literature (Fig. 45-9). Building a relationship of trust with patients is important because the implementation of care involves interaction of a very personal nature.

image

FIG. 45-9 Critical thinking model for urinary elimination planning. ANA, American Nurses Association; ICS, International Continence Society.

Goals and Outcomes

The plan of care for urinary elimination alterations must include realistic and individualized goals along with relevant outcomes. The nurse and the patient need to collaborate in setting goals and outcomes and ultimately in choosing nursing interventions. A general goal is often normal urinary elimination; but sometimes the individual goal differs, depending on the problem. The goals are short or long term. For example, urinary retention following surgery requires a short-term goal: “Patient will have normal voiding with complete bladder emptying within 24 hours.” Relevant expected outcomes for this goal include the following:

• Patient will void within 4 hours.

• Urinary output of 300 mL or greater will occur with each voiding.

• Patient’s bladder is not distended to palpation.

Conversely, the patient with stress incontinence often has a long-term goal that depends on weeks of pelvic floor muscle exercise to achieve urinary control: “Patient will achieve full urinary continence within 8 weeks after start of exercise program (Kegel).” Make sure that goals are reasonably achievable and relevant to the patient’s situation.

Setting Priorities

Urinary elimination is a personal and intimate activity. Establish a relationship with the patient that allows discussion and intervention. While you are collaborating with the patient, his or her priorities become apparent, and he or she should develop an understanding of all the goals.

When a patient has multiple nursing diagnoses (Fig. 45-10), it is important to recognize the primary health problem and its influence on other problems. In the example of the patient with chronic confusion, the resultant incontinence creates several risks. Focusing on the management of incontinence resolves more than one nursing diagnosis. Although physical needs appear to have higher priority, the psychological needs related to self-esteem or sexuality are sometimes a higher priority for the patient. Attention to the patient’s perceived needs is the most satisfactory and successful approach to accomplishing all the goals. Reinforcement of good health habits that are already followed improves compliance with the care plan.

image

FIG. 45-10 Concept map for Mrs. Grayson. UTI, Urinary tract infection.

Teamwork and Collaboration

Incorporate individualized health promotion activities and therapeutic interventions to meet the patient’s needs. Consider the patient’s home environment and normal elimination routines when planning therapies. Collaborate with several health care disciplines, the patient, and the patient’s family. For example, a nurse specialist in urinary continence teaches pelvic floor exercises, whereas a physical therapist designs an exercise plan to increase overall strength and endurance so the patient is able to ambulate to the bathroom. In addition, a health care provider prescribes an indwelling catheter. The nurse monitors the length of time that it is in place and communicates this to the health care provider. Explore the need for home care services and make the appropriate referrals. The family may need to alter the home environment to make it easier and safer for the patient to use the bathroom. The patient’s plan requires multiple interventions.

Stress Urinary Incontinence

Assessment

Mrs. Kay, the nurse, is seeing Mrs. Grayson, a 55-year-old woman, for symptoms of urinary incontinence. Mrs. Grayson is postmenopausal, has a history of three vaginal births, and is “overweight.” She lives with her husband, and her three grown children live nearby. Mrs. Grayson works as a secretary for a local social service agency. She confided to her gynecological practitioner that uncontrollable urine leakage has affected her life. Mrs. Kay’s assessment includes a discussion of Mrs. Grayson’s current health status with emphasis on her urinary concerns.

Assessment Activities Findings/Defining Characteristics*
Ask Mrs. Grayson about the effects of her urinary symptoms on her daily life. She responds, “I find myself being embarrassed and frustrated for losing control. If my bladder is a little full, I dribble easily just picking something up or when I’m on my way to the bathroom. I’m afraid to laugh anymore because I leak urine. At work I try to avoid being close to my co-workers because I’m afraid I might have an odor.”
Ask her what she has been doing about her condition. She states that she has been wearing “one of those little pads” all the time now.
Ask Mrs. Grayson about any other effects caused by her leakage. She begins to cry and states, “You know, I don’t even like to go out to the movies or a party anymore. It’s safer to stay home. I have problems being intimate with my husband because of leaking. We used to go dancing occasionally, but we don’t do that anymore.”
Observe Mrs. Grayson’s behavior. She appears anxious and is slowly pacing the floor.
Take a focused nursing history addressing urinary leakage and other lower urinary tract symptoms. Mrs. Grayson’s report of urine leakage on physical exertion, sneezing, and laughing increases the likelihood of a diagnosis of stress incontinence. Her risk factors for this condition include a history of three pregnancies, being postmenopausal, and being overweight. The history helps to define the proper interventions.
Have Mrs. Grayson complete a 3-day 24-hour log of urination. The bladder log provides objective verification of urine elimination pattern and patterns of urine leakage and baseline for evaluation of effectiveness. It also demonstrates pattern of voiding that indicates more serious urinary problems related to urinary tract infections or other renal diseases (Lewis et al., 2011).

Implementation

Complete independent and collaborative interventions to help the patient achieve the desired outcomes and goals. The independent activities are those in which nurses use their own judgment. An example of this is teaching self-care activities to the patient. Collaborative activities are those prescribed by the health care provider and carried out by the nurse such as medication administration.

Health Promotion

Health promotion assists the patient in understanding and participating in self-care practices to preserve and protect healthy urinary system function. You can achieve this focus using several means.

Patient Education: Success of therapies aimed at eliminating or minimizing urinary elimination problems depends in part on successful patient education (Box 45-6). Although many patients need to learn about all aspects of urinary elimination, first focus the teaching on their specific elimination problems. For example, patients who practice poor hygiene benefit most from learning about normal sterility of the urinary tract and how frequent handwashing and proper perineal hygiene reduce the risks for infection. Patients also learn the significance of symptoms of urinary alterations so they can initiate early preventive health care.

Patient Teaching

Urinary Elimination Problems Related to Urinary Sphincter Dysfunction

Objective

• Patient will achieve continence through increased sphincter control.

Teaching Strategies

• Have patient attempt to tighten urinary sphincter during urination to feel the sensations associated with urinary sphincter contraction.

• Teach patient progressive use of pelvic floor exercises (Kegel exercises).

• Provide written instructions and/or audiotape for reinforcement of technique.

• Have patient sit or stand without tensing muscles of legs, buttocks, or abdomen.

• Have patient contract circumvaginal muscles and urinary and anal sphincters for 10 seconds and then relax for 10 seconds.

• Have patient repeat these cycles for 30 to 100 times per day.

• For maintenance, have patient do 1 to 2 sets per week. Patient should contract pelvic muscles and sphincters before sneezing, coughing, or lifting.

• Maintain optimum strength through practicing hard contractions.

• Teach and monitor use of a voiding record. Inform patient that it may take 2 to 4 weeks of exercises before improvement is seen.

Evaluation

• Ask patient and caregiver about voiding record to identify changes in patterns of urinary elimination.

• Ask patient and caregiver about degree of satisfaction related to control achieved in urinary elimination.

• Ask patient and caregiver about selection and usage of incontinence control devices.

Teaching strategies modified from Bradway C, Cacchione P: Teaching strategies for assessing and managing urinary incontinence in older adults, J Gerontol Nurs 36(7):18, 2010; Touhy TA, Jett KF: Ebersole and Hess’ Gerontological nursing healthy aging, ed 3, St Louis, 2010, Mosby.

You can easily incorporate teaching when giving nursing care. For example, a good time to discuss the benefits of increasing fluid intake is while giving fluids with medications or meals. Often you are more successful in teaching about perineal hygiene while giving a bath or performing catheter care.

Promoting Normal Micturition: Maintaining normal urinary elimination helps to prevent many urination problems. Many nursing measures promote normal voiding in patients at risk for urination difficulties and in those with established urination problems. Some of these measures are independent nursing interventions.

Stimulating Micturition Reflex: A patient’s ability to void depends on feeling the urge to urinate, being able to control the urethral sphincter, and being able to relax during voiding. Help patients learn to relax and stimulate the reflex to void by helping them assume the normal position for voiding. A woman is better able to void in a squatting or sitting position. If the patient is unable to use toilet facilities, position him or her in a squatting position on a bedpan (see Chapter 46) or bedside commode. A man voids more easily in the standing position. If the man cannot reach toilet facilities, have him stand at the bedside and void into a urinal (a metal or plastic receptacle for urine) (Fig. 45-11). At times it is necessary for one or more nurses to help a man stand.

FIG. 45-11 Types of male urinals.

Other measures that promote relaxation and the ability to void include sensory stimuli. The sound of running water helps many patients void through the power of suggestion. Stroking the inner aspect of the thigh stimulates sensory nerves and promotes the micturition reflex. You can also pour warm water over the patient’s perineum and create the sensation to urinate. If you need to measure urine output, first measure the volume of water that you pour over the perineal area.

Maintaining Elimination Habits: Many patients follow routines to promote normal voiding. In a hospital or long-term care facility health care routines often conflict with those of patients. Integrating patients’ habits into the care plan fosters normal voiding and helps prevent problems related to urination.

Maintaining Adequate Fluid Intake: A simple method of promoting normal micturition is maintaining optimal fluid intake. A patient with normal renal function who does not have heart or kidney disease needs to drink 2200 to 2700 mL of fluid daily. However, a minimal daily intake of 1200 to 1500 mL of fluids is usually adequate unless the patient has a history of UTI.

Increasing fluid intake helps flush out solutes or particles that collect in the urinary system. Because some patients are unwilling to drink 2500 mL of water daily, encourage fluids that the patient prefers. Many vegetables and fruits also have a high fluid content. At home it helps to set a schedule for drinking fluids (e.g., with meals or medications). To minimize nocturia, avoid fluids 2 hours before bedtime.

Promoting Complete Bladder Emptying: Under normal conditions a small amount of a patient’s urine remains in the bladder after voiding (residual urine). Encouraging patients to wait until urine stops flowing or to attempt to void again (double voiding) can improve bladder emptying (Table 45-5). Urinary retention care includes scheduled toileting (Lewis et al., 2011). In addition, Credé’s method or manual compression of the bladder walls with each attempted void may be used (Madineh, 2008). Instruct the patient to place both hands flat on the abdomen below the umbilicus and above the symphysis pubis with the fingers pointed down toward the bladder dome. Have him or her compress the hands downward against the walls of the bladder while tightening the perineum, contracting the abdominal wall, and holding the breath. The maneuver promotes bladder emptying by relaxing the urethral sphincter.

Urinary Incontinence and Treatment Options

Aust Fam Physician 37(3):112, 2008.

Preventing Infection: One of the most important considerations is to prevent infection of the urinary system. Good perineal hygiene that includes cleaning the urethral meatus after each voiding or bowel movement is essential. A minimal daily fluid intake of 1200 to 1500 mL dilutes urine, promotes regular micturition, and flushes the urethra of microorganisms. Voiding after intercourse; not using excessive soap or taking bubble baths; wearing cotton underwear; and drinking enough fluids, especially fluids high in acid ash such as apple or cranberry juice help prevent UTI.

Acute Care

Maintaining Elimination Habits: Patients usually require time to void. Requesting a urine specimen on demand does not contribute to relaxation and normal voiding habits. Give patients at least 30 minutes to provide a specimen. Patients normally void on awakening or before meals; therefore offer the opportunity to use toilet facilities then. Also important is the need to respond to and anticipate patients’ urges to urinate. For example, many older-adult falls are related to the urge to urinate. Anticipate the need and provide for scheduled bathroom visits to help reduce the fall risk in these patients.

Many patients need privacy for voiding. If a patient cannot reach the bathroom and uses a bedside commode or bedpan, make sure that the bedside curtain is closed. Patients who are debilitated and live at home often prefer using a bedside commode screened by a partition or room divider. Young children are often unable to void in the presence of persons other than their parents.

When possible encourage the continued use of special measures that the patient uses to void. Some patients are able to relax and void more easily while reading or listening to music. Having a cup or glass of fluids also promotes urination.

Medications: Drug therapy given alone or with other therapies often helps problems of incontinence or retention. The bladder is innervated by the parasympathetic nervous system. Drugs that block the muscarinic receptors suppress bladder contractions and reduce incontinence caused by bladder irritation. Examples include solifenacin (Vesicare) and oxybutynin chloride (Ditropan). These medications can cause constipation, dry mouth, and skin irritation (Lehne, 2010). Irritants present in the urine such as caffeine or alcohol may cause uncontrolled bladder contractions, and thus patients should avoid them.

When the bladder empties, the detrusor muscle contracts in response to parasympathetic stimulation. Incomplete bladder emptying results from impaired innervation or weakness of the detrusor muscle. The patient experiences retention and possible overflow incontinence. Cholinergic drugs increase contraction of the bladder and improve emptying. Bethanechol (Urecholine) stimulates parasympathetic nerves to increase bladder wall contraction and relax the sphincter. You can administer bethanechol by subcutaneous or oral routes. Cholinergic drugs often cause diarrhea as a side effect (Lehne, 2010).

The dribbling or overflow incontinence seen in men with prostatic enlargement can be treated with an alpha1-adrenergic blocker such as tamsulosin (Flomax). Tamsulosin is given orally and relaxes prostatic smooth muscle, thus relieving obstructive symptoms. This drug has few side effects and does not cause transient hypotension as other alpha-adrenergic blockers do (Lehne, 2010).

Catheterization: Catheterization of the bladder involves introducing a latex or plastic tube through the urethra and into the bladder. The catheter provides a continuous flow of urine in patients unable to control micturition or those with obstructions. It also provides a means of assessing urine output in hemodynamically unstable patients. Because bladder catheterization carries the risk of UTI, blockage, and trauma to the urethra, it is preferable to rely on other measures for either specimen collection or management of incontinence.

Types of Catheterization: Intermittent and indwelling retention catheterizations are the two forms of catheter insertion. With the intermittent technique you introduce a straight single-use catheter (Fig. 45-12, A) long enough to drain the bladder (5 to 10 minutes). When the bladder is empty, you immediately withdraw the catheter. You can repeat intermittent catheterization as necessary, but each catheter insertion increases risk of trauma and infection. It is common for people with spinal cord injury or other neurological problems such as multiple sclerosis to perform self–intermittent catheterization up to every 4 hours daily for months or years. If done correctly with use of clean technique, they frequently do not experience more UTIs; in fact, the UTI rate is lower than for patients with long-term indwelling catheters. An indwelling or Foley catheter (Fig. 45-12, B) remains in place for a longer period, until a patient is able to void voluntarily or continuous accurate urine measurements are no longer needed (Box 45-7).

Box 45-7   Indications for Catheterization

FIG. 45-12 Types of urinary catheters. A, Straight. B, Indwelling (Foley).

The straight single-use catheter has a single lumen with a small opening about 1.3 cm (image inch) from the tip. Urine drains from the tip, through the lumen, and to a receptacle. An indwelling Foley catheter has a small inflatable balloon that encircles the catheter just above the tip. When inflated the balloon rests against the bladder outlet to anchor the catheter in place. The indwelling retention catheter often has two or three lumens within the body of the catheter (see Fig. 45-12, B). One lumen drains urine through the catheter to a collecting tube. A second lumen carries sterile water to and from the balloon when it is inflated or deflated. A third (optional) lumen is sometimes used to instill fluids or medications into the bladder. It is easy to determine the number of lumens by the number of drainage and injection ports at the end of the catheter.

A second type of intermittent catheter has a curved tip. A Coudé catheter is used on male patients who may have enlarged prostates that partly obstruct the urethra. It is less traumatic during insertion because it is stiffer and easier to control than the straight-tip catheter.

Catheters come in many diameters to fit the size of a patient’s urethral canal. Box 45-8 provides suggestions for how to make appropriate decisions regarding catheter selection.

Box 45-8   Guidelines for Appropriate Catheter Selection

• The catheter size should be determined by the size of the patient’s urethral canal. When the French system is used, the larger the gauge number, the larger the catheter size. Generally children require an 8- to 10-Fr, women require a 14- to 16-Fr, and men require a 16- to 18-Fr (Gray et al., 2006). To prevent trauma, the smallest effective catheter size is preferred. Larger sizes than 18-Fr create discomfort, increase risk of blockage, and lead to urinary tract infection, urethral irritation, and erosion (Gray et al., 2006)

• The expected duration of the catheterization determines the catheter material selection.

• Plastic catheters are suitable only for intermittent use because of their inflexibility.

• Latex catheters are recommended for use up to 3 weeks. Be aware of allergies.

• Pure silicon or Teflon catheters are best suited for long-term use (2 to 3 months) because of less encrustation at the urethral meatus.

• Balloon size is important in selecting an indwelling catheter. Balloon sizes range from 3 mL (pediatric) to large postoperative volumes (75 mL). In adults the 5-mL and 30-mL sizes are the most common: The 5-mL size allows for optimal drainage, whereas the 30-mL size is used after prostatectomies to provide hemostasis of the prostatic bed (Gray et al., 2006).

• Use only sterile water to inflate the balloon because saline crystallizes, resulting in incomplete deflation of the balloon at the time of removal.

• If leakage occurs around the catheter, a change in lumen size or use of antispasmodic medication is necessary.

Catheter Insertion: Urethral catheterization requires a health care provider’s order. You must use strict aseptic technique (see Chapter 28). Organizing equipment before the procedure prevents interruptions. The steps for inserting indwelling and single-use straight catheters are basically the same. The difference lies in the procedure taken to inflate the indwelling catheter balloon and secure the catheter. Skill 45-2 on pp. 1071-1079 lists steps for performing female and male urethral catheterization.

Closed Drainage Systems: After inserting an indwelling catheter, maintain a closed urinary drainage system to minimize the risk of infection. Standard urinary drainage bags are plastic and hold about 1000 to 1500 mL of urine. The bag hangs on the bed frame or wheelchair without touching the floor. Never hang the bag on the bedrail because it can accidentally be raised above the level of the bladder. In patients with indwelling catheters you can obtain specimens without opening the drainage system using a special port in the tubing (see Fig. 45-7).

An alternative to a large-volume urinary drainage bag is a small-volume leg bag. A urinary drainage bag attached to the patient’s calf or thigh provides the catheterized patient with greater mobility. These drainage bags are usually worn during the day and replaced at night with a standard drainage bag.

When the patient ambulates, the nurse or patient carries the standard urinary drainage bag below the patient’s waist. As with leg bags, never raise the drainage bag above the level of the patient’s bladder. Urine in the bag and tubing becomes a medium for bacteria, and infection is likely to develop if urine flows back into the bladder.

Most drainage bags contain an antireflux valve to prevent urine in the bag from reentering the drainage tubing and contaminating the patient’s bladder. A spigot at the base of urinary drainage bags provides a means for emptying the bag. The spigot on a leg bag is covered with a protective cap. The spigot on a standard drainage bag always needs to be clamped, except during emptying, and tucked into the protective pouch on the side of the bag (see agency policy). To keep urinary drainage systems patent so urine can flow into the drainage bag, check for kinks or bends in the tubing, avoid positioning the patient on the tubing, and observe for clots or sediment that occlude it. Patients with indwelling catheters have a number of special care needs. Direct nursing measures at preventing infection and maintaining unobstructed flow of urine through the catheter drainage system.

Perineal Hygiene: Buildup of secretions or encrustation at the catheter insertion site is a source of irritation and potential infection. Nurses provide perineal hygiene (see Chapter 39) at least 3 times daily or as needed for a patient with a retention catheter. Soap and water are effective in reducing the number of organisms around the urethra. Accidentally advancing the catheter further into the bladder during cleaning increases the risk of introducing bacteria into the bladder.

Catheter Care: In addition to routine perineal hygiene, many institutions recommend that patients with catheters receive special care 3 times a day and after defecation or bowel incontinence to help minimize discomfort and infection (Skill 45-3 on pp. 1079-1081).

Fluid Intake: All patients with catheters should have a daily intake of 2000 to 2500 mL if permitted. Patients can do this through oral intake or intravenous infusion. A high fluid intake produces a large volume of urine that flushes the bladder and keeps catheter tubing free of sediment. Cranberry, apple, and prune juices are high in acid ash and help prevent infection; conversely citrus juices such as orange, grapefruit, and pineapple should be used sparingly because they can create an environment in the bladder more prone to infection.

Preventing Infection: Maintaining a closed urinary drainage system is important in infection control. A break in the system leads to introduction of microorganisms (Box 45-9). Sites at risk are the site of catheter insertion, the drainage bag, the spigot, the tube junction, and the junction of the tube and bag (Fig. 45-13).

Box 45-9   Evidence-Based Practice

Factors to Decrease Urinary Tract Infections

PICO Question: Which factors decrease the risk of urinary tract infections (UTIs) in hospitalized patients with indwelling urinary catheters?

Evidence Summary

Urinary catheterization is a common procedure in health care settings. Nine percent of patients in hospitals acquire a health care–associated infection. UTIs account for approximately 40% of them (Parker et al., 2009). The risk of catheter-associated urinary tract infections (CAUTIs) increases by the number of days that a catheter remains in place.

Nazarko (2008) stresses that decreasing the risk for CAUTIs starts by avoiding unnecessary use of indwelling catheters and removing them as soon as medically indicated. Indications for catheterization include surgery, urinary retention, and need for accurate measurement of output (Holroyd-Leduc et al., 2007). The authors designed a study to determine the association between indwelling urinary catheterization without a specific medical indication and adverse outcomes. They found that patients older than 70 years with limited functional ability are often catheterized to facilitate their care. The results suggested that nonmedical use of indwelling catheters in older adults may result in longer hospital stays and greater risk of death resulting from the development of a UTI and subsequent development of bacteremia or urosepsis.

Urinary catheters vary in composition and design. Research related to catheter composition focuses on altering the catheter surface to slow biofilm development (adherence of microorganisms to the catheter surface). According to Parker et al. (2009), there is robust evidence supporting the insertion of a silver alloy–coated catheter to reduce the risk of CAUTIs for up to 2 weeks and an antibiotic-impregnated catheter for up to 7 days in adult patients. In addition, further research needs to be conducted on which type of catheter is effective in decreasing the risk of CAUTI for long-term use.

Many catheterizations can be avoided by using noninvasive alternatives. For example, instead of using catheterization to evaluate residual urine in the bladder, a bladder scanner can be used. When it is determined that bladder volume is normal, the invasive procedure of catheterization may not be needed (Chen et al., 2005). In addition, the incidence of CAUTI significantly decreases when nurses give the prescriber daily reminders to remove unnecessary catheters and suggest the use of alternative noninvasive treatments such as condom catheters to manage urinary elimination (Holroyd-Leduc et al., 2007; Nazarko, 2008).

Application to Nursing Practice

• Avoid the routine use of catheters; use only when clinically indicated.

• Collaborate with health care providers to remove catheters when medical indications no longer exist.

• Suggest noninvasive continent devices such as condom catheters to reduce the risk of UTI and resulting complications.

• Nurses need to be patient advocates by taking an active role in monitoring duration of treatment.

FIG. 45-13 Potential sites for introduction of infectious organisms into a urinary drainage system.

In addition, monitor the patency of the system to prevent pooling of urine within the tubing. Urine in the drainage bag is an excellent medium for microorganism growth. Bacteria can travel up drainage tubing to grow in pools of urine. If this urine flows back into the patient’s bladder, an infection is more likely to develop. Many urine drainage systems are equipped with an antireflux valve. Suggestions for ways to prevent infections in patients with catheters are provided in Box 45-10.

Box 45-10   Tips for Preventing Infection in Patients with Catheters

• Follow good hand hygiene techniques (see Chapter 28).

• Do not allow the spigot on the drainage system to touch a contaminated surface.

• Only use sterile technique to collect specimens from a closed drainage system.

• If the drainage tube becomes disconnected, do not touch the ends of the catheter or tubing. Wipe the end of the tubing and catheter with an antimicrobial solution before reconnecting.

• Ensure that each patient has a separate receptacle for measuring urine to prevent cross-contamination.

• Prevent pooling of urine in the tubing and reflux of urine into the bladder.

• Avoid raising the drainage bag above the level of the bladder.

• If it becomes necessary to raise the bag during transfer of the patient to a bed or stretcher, clamp the tubing or empty its contents to the drainage bag first.

• Provide for drainage of urine from the tubing to the bag by positioning the tubing.

• Before exercise or ambulation drain all urine from the tubing into the drainage bag.

• Avoid prolonged kinking or clamping of the tubing.

• Empty the drainage bag at least every 8 hours. If you note large outputs, empty more frequently.

• Encourage fluid intake (if not contraindicated).

• Remove the catheter as soon as clinically necessary (Fernandez and Griffiths, 2006).

• Tape or secure the catheter appropriately for the patient (see Skill 45-2).

• Perform routine perineal hygiene per agency policy and after defecation or bowel incontinence (see Skill 45-3).

Catheter Irrigations and Instillations: To maintain the patency of indwelling urinary catheters, it is sometimes necessary to irrigate or flush a catheter with sterile solution. If a catheter becomes plugged with pus or sediment, it is best to change it rather than irrigate because irrigation washes the pus and sediment back into the bladder, creating a worse infection. Change the catheter as needed. It is appropriate to use irrigation after surgery for blood clots and short-term catheter use; but for long-term use irrigation can create a chronic sediment and pus problem, requiring lifelong irrigation in long-term indwelling catheters. For patients with bladder infections, a health care provider often orders antiseptic or antibiotic bladder irrigations to wash out the bladder or treat local infection. In both irrigations follow sterile aseptic technique.

Before performing irrigation assess the catheter for blockage. If the amount of urine in the drainage bag is less than the patient’s intake or output during the previous shift, expect some blockage. If urine does not drain freely, milk the tubing. Milk the tube by squeezing and then releasing it, starting at a point close to the patient and then out to the drainage bag so a clot or sediment is not forced back into the catheter. Many times this takes care of the problem without irrigation.

Maintenance of a closed system is recommended during intermittent irrigations or instillations. This technique is effective for irrigating a partially blocked catheter or for bladder instillations. One method of closed-bladder irrigation provides for frequent intermittent irrigations or continuous irrigation without disruption of the sterile catheter system through use of a three-way catheter (Skill 45-4 on pp. 1081-1084). This method is used most often in patients who have had genitourinary surgery and are at risk for blood clots and mucus fragments occluding the catheter. The other method involves accessing the closed drainage system to instill bladder irrigations (see Skill 45-4). This method is often used for unanticipated irrigation or intermittent instillations.

Removal of Indwelling Catheter: When removing an indwelling catheter, promote normal bladder function and prevent trauma to the urethra. Removing a catheter requires a clean, disposable towel; a trash receptacle; and a sterile syringe the same size as the volume of solution within the inflated balloon of the catheter. Perform hand hygiene and put on clean gloves before removing the catheter. The end of each catheter contains a label that denotes the volume of solution (5 to 30 mL) within the balloon. If a different volume was used, there should be a notation on the patient record.

Position the patient in the same position as during catheterization. Some institutions recommend collecting a sterile urine specimen at this time or sending the catheter tip for culture and sensitivity tests. After removing the tape, place the towel between a female patient’s thighs or over a male patient’s thighs. Insert the syringe into the balloon injection port. Most ports are self-sealing and require that only the tip of the syringe be inserted. Slowly withdraw all of the solution to deflate the balloon totally. If a portion of the solution remains, the partially inflated balloon traumatizes the urethral canal as the catheter is removed. After deflation, explain that the patient will feel a burning sensation as the catheter is withdrawn. Then pull the catheter out smoothly and slowly.

It is normal for the patient to experience some dysuria, especially if the catheter has been in place several days or weeks. Until the bladder regains full tone, some patients also experience frequency of urination or urinary retention.

Assess the patient’s urinary function by noting the first voiding after catheter removal and documenting the time and amount of voiding for the next 24 hours. If amounts are small, frequent assessment of bladder for distention is necessary. If 4 hours have elapsed without voiding or the patient experiences discomfort, it often becomes necessary to reinsert the catheter.

Alternatives to Urethral Catheterization: To avoid the risks associated with urethral catheters, two alternatives are available for urinary drainage.

Suprapubic Catheterization: Suprapubic catheterization involves surgical placement of a catheter through the abdominal wall above the symphysis pubis and into the urinary bladder. A health care provider performs the procedure under local or general anesthesia. The catheter is anchored in place with sutures, a commercially prepared ring seal, or both. Urine drains into a urinary drainage bag. Maintenance of the tubing and drainage bag is the same as for an indwelling catheter. Studies comparing the use of this method of urinary drainage with indwelling catheters have shown mixed results. Infection rates may be slightly lower; however, long-term complications are similar (Doughty, 2006). Sediment, clots, or the abdominal wall itself can block the suprapubic catheter. Adequate fluid intake helps to minimize risk of blockage by increasing urine flow. The suprapubic catheter must remain patent at all times. Monitor the patient’s I&O carefully, monitor the urine characteristics, and observe for signs of infection (e.g., fever and chills). Also administer skin care around the insertion site. This method may be used in men and women.

Condom Catheter: The second alternative to catheterization is the condom catheter (Box 45-11), which is suitable for incontinent or comatose men who still have complete and spontaneous bladder emptying. The condom is a soft, pliable, latex sheath that slips over the penis. Patients wear it only at night or continuously, depending on their needs. There are three general methods of securing a condom catheter. One method uses a strip of elastic tape or rubber that encircles the top of the condom to secure it in place. Another type uses a self-adhesive condom sheath. The third method uses an inflatable ring within the condom to secure placement. Take care to ensure that, whatever type or size is used, blood supply to the penis is not impaired. Never use standard adhesive tape to secure a condom catheter because it does not expand with change in penis size and is painful to remove.

Box 45-11   Procedural Guidelines

Applying a Condom Catheter

Delegation Considerations

After assessing patient for latex allergy, you can delegate the skill of applying a condom catheter to nursing assistive personnel (NAP). The nurse instructs NAP to:

• Be sensitive to privacy needs of patients.

• Be sure that the skin of the penile shaft is intact and free from swelling, redness, or open lesions before applying the condom catheter.

• Ask for assistance if the NAP is uncertain how to apply the adhesive strip that secures the condom catheter.

Equipment

Condom catheter (sometimes comes with self-adhesive or an elastic adhesive), collection bag, skin preparation, basin with warm water, towel and washcloth, clean gloves, scissors or hair guard, bath blanket and sheet

1. Check health care provider’s order. Identify patient using two identifiers (i.e., name and birth date or name and account number) according to facility policy.

2. Perform hand hygiene.

3. Assess urinary elimination patterns, patient’s ability to urinate voluntarily, and continence.

4. Assess mental status of patient and explain procedure.

5. Provide for privacy by closing room door or bedside curtain. Raise bed to working height and lower side rail on working side.

6. Prepare condom catheter and drainage bag and tubing (see manufacturer directions).

7. Assist patient to supine or sitting position. Place bath blanket over upper torso; fold sheet over lower torso so only penis is exposed.

8. Apply clean gloves, provide perineal care (see Chapter 28), and dry thoroughly. If patient is uncircumcised, return foreskin to normal position.

9. If needed, clip hair at base of penile shaft. Do not shave the pubic area. An alternative to trimming pubic hair is placing a hair guard (see manufacturer directions) over penis before applying catheter.

10. Assess condition of penis and scrotum. Use manufacturer measuring guide to measure diameter of penis in flaccid state. Penile shaft should be at least 2 cm (approximately 1 inch) in length to ensure successful application.

11. Option: Apply skin-cleaning preparation to penile shaft and allow to dry.

12. Hold penis along shaft in nondominant hand. With dominant hand hold condom sheath at tip of penis and smoothly roll sheath onto penis. Allow 2.5 to 5 cm (1 to 2 inches) of space between tip of penis and end of catheter (see illustration).

STEP 12 Distance between end of penis and tip of condom.

13. Secure condom catheter according to manufacturer directions.

a. If using elastic adhesive, wrap strip of adhesive over condom to secure it in place by using spiral technique (see illustration). Note: Never use adhesive tape.

STEP 13a Apply elastic tape in spiral fashion to secure condom catheter to penis.

b. For self-adhesive catheter, apply catheter as in Steps 11 and 12; then apply gentle pressure on penile shaft for 10 to 15 seconds to secure.

14. Connect drainage tubing to end of condom catheter. Be sure that condom is not twisted. Connect catheter to large-volume drainage bag or leg bag (see illustration). Attach large-volume drainage bag to lower bed frame. Coil excess tubing on bed.

STEP 14 Attach condom catheter tubing to leg bag.

15. Make patient comfortable, lower bed, and place side rails as appropriate.

16. Dispose of contaminated supplies, remove gloves, and perform hand hygiene.

17. Observe urinary drainage, drainage tube patency, condition of penis, and tape placement.

The end of the condom is attached to plastic drainage tubing and a bag that you attach to the side of the bed or strap to the patient’s leg. The condom catheter itself poses little risk of UTI. Infections usually result from buildup of secretions around the urethra, trauma to the urethral meatus, or buildup of pressure in the outflow tubing. If the condom catheter is made of opaque material, remove it daily to check for skin irritation. Some new condom catheters are more transparent, and you are able to observe the skin through them more easily. Change the condom catheter daily. With each catheter change clean the urethral meatus and penis thoroughly. Check the drainage tubing often for patency because twisting the condom at the drainage tube attachment irritates the skin and obstructs urine outflow. Make sure that the tip of the penis is at the end of the catheter. If there is space between the end of the penis and the catheter, urine can pool in this space and excoriate the end of the penis.

For a man with a retracted penis, maintaining a conventional condom catheter often proves difficult. Special devices are available to help alleviate this problem (Fig. 45-14). Consult manufacturer guidelines for product application.

No collection devices for women are as effective as the condom catheter is for men; thus frequently the only devices used are pads and protective clothing. To maintain dignity, do not refer to pads and protective clothing as adult diapers and change them frequently to control odor. Only use these products temporarily to minimize or prevent episodes of incontinence while treatment is ongoing. Monitor patients frequently and provide good skin care to prevent irritation caused by urine. Some manufacturers have developed a female urinal; however, their ease of use may be an issue.

Restorative Care

Some patients regain normal urinary voiding function through special activities such as bladder retraining, habit training, or cognitive therapy. In some cases self-catheterization may be used to restore a measure of control to the patient.

Strengthening Pelvic Floor Muscles: Patients who have stress or urge urinary incontinence and difficulty starting and stopping urination may benefit from pelvic floor exercises. Pelvic floor exercises, also known as Kegel exercises, improve the strength of pelvic floor muscles and consist of repetitive contractions of muscle groups. These exercises have demonstrated effectiveness in treating stress incontinence, OAB, and mixed cause of urinary incontinence. A patient begins these exercises during voiding to learn the technique. They are then practiced at nonvoiding times. Improvement is usually gradual. Patients need to be alert and motivated to perform the exercises. They need to continue to use them to maintain effectiveness (see Box 45-6). The exercises are noninvasive and carry a low risk of adverse effects.

Bladder Retraining: The goal of bladder retraining is to reduce the voiding frequency and perhaps the bladder capacity (Doughty, 2006). This method is a specific program for patients who have a decreased urge to void or have stress incontinence since it keeps the bladder from getting full; thus there is less dribbling. Ultimately the overall goal of this retraining is to restore a normal pattern of voiding by teaching patients to keep the patient continent. Initially patients keep a bladder diary or log noting times, volumes, fluid intake, and any other related symptoms. This provides a baseline for comparison during the retraining. For bladder retraining to be successful, patients must agree to it and be alert and physically able to follow a training program. Bladder retraining is very important in long-term care and rehabilitation facilities. Remember that keeping a patient with a severely spastic bladder from frequent toileting causes pain for the patient. Nurses should never refuse to toilet a patient. Urological consultation can be helpful; and, if treated properly, bladder capacity will increase.

Assess the patient’s current pattern of urination. This information allows the nurse to plan a program that often takes 2 weeks or more to learn. Although patients may start the program in the hospital or in rehabilitation, they may need to continue it in an extended care facility or at home. Generally the patient is asked to suppress urination for each voiding and increase time by increments of 15 minutes every week. The goal is to void every 3 to 4 hours in volumes of 240 to 500 mL. If the patient has an underlying UTI, treat this at the same time.

As part of restorative and rehabilitative care, patients with different types of incontinence may benefit from specific measures that address particular continence issues. These guidelines help patients control factors that affect the number of incontinence episodes.

The following measures may help patients with stress urinary incontinence to gain control over urination:

• Learning exercises to strengthen the pelvic floor (see Box 45-6)

• Initiating a toileting schedule on awakening, at least every 2 hours during the day and evening, before getting into bed, and every 4 hours at night (individualizing time frame as needed)

• Avoiding an overfilled bladder because this increases chances of incontinence related to increased bladder pressure

• Minimizing tea, coffee, other caffeine drinks (increases urine production, frequency, and urgency) and alcohol (increases urine production)

• Taking prescribed diuretic medication early in the morning

• Following a weight-control program if obesity is a problem that is causing increased abdominal pressure

Habit Training: A patient with functional incontinence benefits from habit training, which helps patients improve voluntary control over urination. A patient establishes a flexible toileting schedule based on his or her pattern. Have the patient establish the pattern by documenting episodes of incontinence and scheduling voiding opportunities just before the urge time interval. The goal is to keep the patient dry. Help him or her to the bathroom before the urge usually occurs. Time fluids and medications to prevent interference with the toileting schedule. Patients with moderate or severe mental or physical dysfunction and those who have normal bladder function or overflow reflex incontinence benefit from habit training. When combined with positive reinforcement to reward successful voiding, this approach is also called prompted voiding.

Building Competency in Safety

You are caring for a 70-year-old male patient who has urgency and is incontinent of urine. An indwelling catheter is prescribed for the incontinence. What is your responsibility in this situation to promote patient safety? Provide the rationales for your answer.

Answers to questions can be found on the Evolve website.

Self-Catheterization: Some patients with chronic disorders such as spinal cord injury learn to perform self-catheterization. A patient must be able to physically manipulate equipment and assume a position for successful catheterization. You teach the patient the structures of the urinary tract, clean-versus-sterile technique, the importance of adequate fluid intake, and the frequency of self-catheterization. Generally the goal is to have patients perform self-catheterization 4 to 6 times a day with volumes of 400 to 500 mL; but be sure to individualize the schedule.

Maintenance of Skin Integrity: The normal acidity of urine is irritating to skin. Urine allowed to remain in contact with the skin becomes alkaline, causing encrustations or precipitates to collect on it, fostering breakdown. Washing with mild soap and warm water is the best way to remove urine from skin. Body lotion keeps skin moisturized, and petroleum-based ointments provide a barrier to the urine. Patients who wet their clothing need to receive partial baths and dry clothing after voiding. Continuous exposure of the perineal area or skin around an ostomy leads to gradual maceration and excoriation (see Chapter 48) requiring special care.

When the skin becomes irritated or inflamed, often the health care provider prescribes a cream or spray containing steroids (e.g., Kenalog) to reduce inflammation. If fungal growth develops, the antifungal drug nystatin (Mycostatin), available in cream or powder, is effective.

Promotion of Comfort: Patients with urinary alterations become uncomfortable as a result of the symptoms of urinary problems. Frequent or unpredictable voiding, dysuria, and painful distention are sources of discomfort.

The incontinent patient gains comfort from having clean, dry clothing. When stress incontinence is the problem, a protective pad offers protection against soiling. Wet clothing adheres to the skin and can cause rubbing and irritation.

Urinary analgesics that act on the urethral and bladder mucosa (e.g., phenazopyridine) relieve dysuria. Often you combine this drug with sulfonamide antibiotics in preparations such as Azo-Gantanol and Azo-Gantrisin. Patients taking drugs with phenazopyridine need to be aware that their urine will be orange. They must drink large amounts of fluids to prevent toxicity from the sulfonamides and maintain optimal flow through the urinary system (Lehne, 2010).

If the patient has local discomfort from an inflamed urethra, an iced sitz bath provides pain relief. The patient is often relaxed after a sitz bath; thus voiding occurs easily. Patients cannot relieve pain of distention unless they are able to empty the bladder. Interventions that stimulate micturition or intermittent catheterization may be the only sources of pain relief.

Evaluation

Through the Patient’s Eyes

The patient is the best source of evaluation of outcomes and responses to nursing care (Fig. 45-15). Note his or her responses to questions about urination. Does he or she seem hesitant or embarrassed? Psychosocial factors such as culture or sexuality sometimes influence the patient’s response. Because urination is often considered a private matter, some people find it difficult to talk about their voiding habits. Remember that urinary elimination problems are not just physiological in nature. Be sensitive to any changes in self-concept and sexuality. Self-concept, which includes body image, self-esteem, roles, and identity, develops over a life span. Because the penis is an organ for both urination and sex, urinary dysfunction often greatly affects a man’s self concept.

Patient Outcomes

You also evaluate the effectiveness of nursing interventions through comparisons with the outcome goals. Evaluate for changes in the patient’s voiding pattern and continued presence of urinary tract alteration. Actual outcomes are compared with expected outcomes to determine success or partial success in achieving those outcomes. Examples of questions to ask for evaluation include:

• “Tell me, how frequently are you voiding now?”

• “Do you continue to have the feeling of urgency every time you void?”

• “Have the symptoms of urgency decreased since you changed your caffeine intake?

• “Do you still have burning when you pass urine?

• “Do you still feel uncomfortable over your lower abdomen?”

Evaluation of an intervention that may take weeks to accomplish such as pelvic floor exercises requires follow-up beyond the hospital or rehabilitation facility. Specific information about how well an intervention has met the need determines if you need to revise the plan of care. Continuous evaluation allows you to determine whether any new symptoms or nursing diagnoses have developed. Help the patient redefine goals when impairment in function is not likely to be altered as completely as the patient might like.

Safety Guidelines for Nursing Skills

Ensuring patient safety is an essential role of the professional nurse. To ensure patient safety, communicate clearly with members of the health care team, assess and incorporate a patient’s priorities of care and preferences and use the best evidence when making decisions about your patient’s care. When performing the skills in this chapter, remember the following points to ensure safe individualized patient care.

• Follow principles of surgical and medical asepsis as indicated when performing catheterizations, handling urine specimens, or helping patients with their toileting needs.

• Identify patients at risk for latex allergies (i.e., patient history of hay fever; asthma; and allergies to certain foods such as bananas, grapes, apricots, kiwi fruit, and hazelnuts).

• Identify patients with allergies to povidone-iodine (Betadine). Provide alternatives such as chlorhexidine.

Skill 45-1 Collecting Midstream (Clean-Voided) Urine Specimen image

image

Unexpected Outcomes and Related Interventions:

1. Urine specimen is contaminated with feces or toilet paper.

• Repeat instruction to patient or assist patient in obtaining specimen.

• Obtain a new specimen.

• Request an order for using a straight catheterization to obtain specimen.

2. Specimen is accidentally discarded.

• Repeat specimen collection.

Recording and Reporting:

• Record date and time urine specimen was obtained in nurses’ notes.

• Notify health care provider of any significant abnormalities.

Home Care Considerations:

• If patient is to collect specimen as outpatient, a clean technique may be used. Provide instruction for collection and appropriate equipment.

• Provide information about storing specimen until time for delivery to health care provider’s office or hospital laboratory.

Unexpected Outcomes and Related Interventions:

1. Urethral or perineal irritation is present.

• Observe for catheter leaking; replace if necessary.

• Assess that indwelling catheter is anchored properly.

• Perform perineal hygiene and catheter care more frequently.

2. Patient has fever, and/or odor is present; or he or she experiences small frequent voiding, burning or bleeding on voiding.

• Obtain clean-voided urine specimen.

• Notify health care provider.

3. Patient experiences urinary retention and is unable to void after you remove the catheter.

• Provide adequate fluid intake and ensure patient privacy.

• If patient is unable to void 4 hours following catheter removal, notify health care provider.

Recording and Reporting:

• Report and record type and size of catheter inserted, amount of fluid used to inflate the balloon, characteristics and amount of urine, reasons for catheterization, specimen collection if appropriate, and patient’s response to procedure and teaching concepts.

• Initiate intake and output (I&O) record.

• If catheter is definitely in bladder and no urine is produced within an hour, immediately report absence of urine to health care provider.

Home Care Considerations:

• Patients at home often use a leg bag during the day and switch to a large-volume bag at night so sleep is uninterrupted.

• Patients who catheterize themselves at home frequently use a clean technique.

Skill 45-3 Indwelling Catheter Care

image

Unexpected Outcomes and Related Interventions:

1. Urethral discharge or perineal irritation present

• Observe for leaking from around catheter; catheter may need replacing.

• Increase frequency of indwelling catheter care.

• Notify health care provider.

2. Accidental catheter dislodgement

• Notify health care provider.

• Assess for urethral trauma.

• Monitor urine output.

Recording and Reporting:

• Report and record presence and characteristics of drainage, condition of perineal tissue, and any discomfort reported by patient.

• If infection is suspected, report findings to health care provider.

Home Care Considerations:

• If patient is discharged with indwelling catheter, teach patient and family catheter care and signs and symptoms to report to nurse or health care provider.

Skill 45-4 Closed Catheter Irrigation

image

image

image

image

image

image

image

Unexpected Outcomes and Related Interventions:

1. Irrigant or instillation solution not returning; or continuous solution not flowing at prescribed rate, which indicates possible occlusion of catheter

• Examine tubing for kinks, clots, or urine sediment.

• Notify health care provider if irrigant or instillation is retained, patient complains of pain, or bladder is distended.

2. Cloudy or foul urine, fever

• Monitor fever.

• Notify health care provider.

• Obtain sterile urine specimen if ordered by health care provider.

3. Increase in bladder spasms; indicates occlusion of catheter with foreign object (e.g., blood clot)

• Notify health care provider.

• Perform intermittent irrigations until clots clear as directed.

Recording and Reporting:

• Record type and amount of irrigation solution used, amount returned as drainage, and the character of drainage.

• Record and report any findings such as complaints of bladder spasms, inability to instill fluid into bladder, and/or presence of blood clots.

Home Care Considerations:

• If patient is discharged with indwelling catheter and requires bladder irrigations, instruct the patient and/or the family on proper care.

• Because irrigation or instillation carries a risk of contamination, assess the level of understanding of surgical asepsis by the patient and family and provide appropriate instruction. The patient and family need guidelines for the skill and for conditions requiring a call to the health care provider.

Key Points

• Voluntary control from higher brain centers and involuntary control from the spinal cord influence the act of micturition or voiding.

• Symptoms common to urinary disturbances include frequency, urgency, dysuria, polyuria, oliguria, incontinence, and difficulty in starting the urinary stream.

• When collected properly, a clean-voided urine specimen does not contain bacteria from the urethral meatus.

• Methods of promoting the micturition reflex help patients sense the urge to urinate and control urethral sphincter relaxation.

• An increased fluid intake results in increased diluted urine formation that reduces the risk of urinary tract infections.

• An indwelling urinary catheter remains in the bladder for an extended period, making the risk of infection greater than with intermittent catheterization.

• Catheter irrigation becomes necessary when the catheter becomes occluded with sediment or blood clots.

• A catheter drainage system should be a closed system positioned to allow free drainage of urine by gravity.

• Incontinence is classified as functional, overflow, stress, urge, or total. Each type has specific nursing interventions.

• Follow specific guidelines for catheter selection so the catheter does not cause harm.

Clinical Application Questions

Preparing for Clinical Practice

Mrs. Grayson is a 55-year-old woman who has had problems with stress incontinence for the past 2 years. She has not spoken to anyone about her problems because she is embarrassed. She finally confides to her health care practitioner that the problem is causing her to avoid social situations and she would like help to regain urinary control. Mrs. Grayson weighs 200 pounds, and her height is 5 feet 1 inch. She has been referred to a continence specialist. A plan of care was developed after a thorough assessment of her urinary pattern and symptoms.

1. She has recently begun Kegel exercises to attempt improvement in her urinary control. She doesn’t see any improvement. She has been trying to deal with the problem by using an absorbent pad in her underwear, but she feels as though everyone knows her problem. What additional teaching does Mrs. Grayson need?

2. Two months after your first encounter with Mrs. Grayson, she has been seen by her primary health care provider for burning on urination with increased frequency and urgency. She has also noted blood in her urine for a week. What is Mrs. Grayson experiencing and what can you teach her to minimize her symptoms?

3. Mrs. Grayson says she is not satisfied with her current state of urinary control and has decided on a more permanent solution to her stress incontinence. She opts for a minimally invasive procedure that will provide support for the urethra. She will be going home with an indwelling catheter. She asks how to care for the catheter while she is home. She does not want another urinary tract infection. What do you tell her about measures at home to remain infection free?
