Chapter 44: Urinary Elimination Flashcards

Physiology and Fundamentals of Urinary Elimination

• Mechanism of Elimination:
  • Urinary elimination is a precise physiological system of filtration, reabsorption, and excretion.
  • Maintains fluid and electrolyte balance while simultaneously filtering and excreting water-soluble metabolic wastes.
• Primary Organs and Daily Output:
  • Kidneys serve as the primary organs of elimination.
  • Functional units called nephrons perform the main work of filtration and elimination.
  • Average adult urine output ranges between $1,000\text{ to }2,000\,mL/\text{day}$.
• Elimination Pathway:
  • Post-filtration urine flows from the kidneys through the ureters into the urinary bladder, which acts as a storage reservoir.
  • When an adequate volume of urine accumulates in the bladder ($250\text{ to }450\,mL$ in adult clients), stretch receptors embedded within the bladder wall fire signals to the brain indicating the urge to void.
  • Urination proceeds when the individual voluntarily relaxes the internal and external urethral sphincters located at the base of the bladder and urethra, allowing urine to exit the body via the urethra.
• Exogenous Factors Affecting Elimination:
  • Surgical procedures, immobility, pharmacologic agents, and therapeutic diets directly influence normal urinary elimination.

Classification and Care of Urinary Diversions

• Definition and Clinical Indications:
  • Surgical creation of an alternative pathway to reroute urine flow from its normal path.
  • Created as temporary or permanent diversions for clients experiencing severe conditions such as bladder cancer or traumatic bladder injury.
  • Body Image Considerations: Share operational similarities with bowel diversions; clients often express identical body image and psychosocial concerns.
• Categorization of Diversions:
  • Continent Diversions: Feature an internal abdominal reservoir created surgically, allowing clients to maintain voluntary controlled elimination of urine.
  • Incontinent Diversions: Lack internal control mechanisms; urine drains continuously from the abdominal stoma into an external collection appliance.
• Specific Urinary Diversion Types:
  • Ureterostomy (Ileal Conduit): Incontinent diversion where the surgeon connects one or both ureters directly to the abdominal wall surface via a stoma.
  • Nephrostomy: Incontinent diversion where a tube is surgically inserted into the renal pelvis and attached via a stoma to the abdominal wall surface.
  • Kock Pouch (Continent Ileal Bladder Conduit): Continent diversion in which a reservoir is constructed from a segment of the ileum. Pouch emptying requires clean straight catheterization every $2\text{ to }3\,\text{hr}$ initially, expanding to every $5\text{ to }6\,\text{hr}$ once the pouch achieves maximum volumetric capacity.
  • Neobladder: A continent internal reservoir constructed from an ileal segment and surgically connected to both the ureters and urethra. Clients preserve continence and learn to void by straining their abdominal musculature.
• Nursing Interventions for Diversions:
  • Consult a Wound Ostomy Continence Nurse (WOCN) to assist in managing incontinent urinary diversions.
  • Rigorously inspect and monitor the stoma and surrounding peristomal skin for any evidence of tissue breakdown or irritation.

Factors Influencing Urinary Elimination Across the Lifespan

• Systemic and Structural Factors:
  • Poor abdominal and pelvic floor muscle tone.
  • Acute and chronic pathological disorders.
  • Spinal cord injuries disrupting neural pathways.
• Age-Related Factors Across Lifespan:
  • Pediatric Clients: Full voluntary bladder control is typically achieved by $4\text{ to }5\text{ years}$ of age.
  • Older Adult Males: Benign or malignant prostate enlargement can obstruct the bladder outlet, producing urinary retention and urgency, which increases susceptibility to overflow incontinence and urinary tract infections (UTIs).
  • Childbirth and Gravida Impact: Gravitational pull and vaginal childbirth weaken the pelvic floor, predisposing clients to bladder prolapse and stress incontinence (managed via pelvic floor / Kegel exercises).
  • Post-Menopausal Females: Declining estrogen levels impair perineal tissue tone, leading to increased rates of urinary urgency, stress incontinence, and recurrent UTIs.
  • Older Adult Physiological Changes:
  • Reduction in the total number of functioning nephrons.
  • Loss of bladder smooth muscle tone causing urinary frequency.
  • Inefficient bladder emptying causing elevated post-void residual urine volumes, significantly increasing UTI risks.
  • Decreased overall bladder capacity leading to an increase in nocturia.
  • Presence of underlying chronic systemic illnesses.
  • Physical limitations interfering with personal mobility and manual dexterity needed for toileting.
• Pregnancy Considerations:
  • The expanding uterus compresses the bladder and compromises storage capacity.
  • Circulatory volume increases by $30\%\text{ to }50\%$, increasing renal blood flow, renal workload, and total urine output.
  • Systemic release of the hormone relaxin induces relaxation of the urinary sphincter.
• Dietary Influences:
  • High dietary sodium intake promotes fluid retention, leading to decreased urine output.
  • Consumption of caffeine and alcohol increases output due to diuretic properties.
• Immobility:
  • Impaired physical mobility impairs timely transfers to the bathroom, triggering functional incontinence.
• Psychosocial Factors:
  • Emotional stress and heightened anxiety levels.
  • Avoidance of public toilet facilities.
  • Lack of adequate privacy during acute care hospital admissions.
  • Time constraints during scheduled voiding windows (e.g., rigid bathroom schedules in elementary school settings).
• Pain Conditions:
  • Voluntary suppression of the urge to void due to severe pain in the urinary tract.
  • Ureteral lumen obstruction causing acute renal colic.
  • Severe joint pain or arthritis impairing physical mobility, causing delayed voiding.
• Surgical Interventions:
  • Administration of general anesthesia and opioid analgesics alters glomerular filtration rate (GFR), resulting in transiently reduced urine output.
  • Lower abdominal surgical procedures induce local tissue edema and inflammation, creating mechanical urinary tract obstruction.
• Pharmacologic Impacts:
  • Diuretics: Block renal tubular water reabsorption, driving marked diuresis.
  • Antihistamines and Anticholinergics: Inhibit detrusor muscle contraction, causing severe urinary retention.
  • Chemotherapy Agents: Create a toxic cellular environment for renal parenchyma.
• Drug-Induced Urine Color Changes:
  • Phenazopyridine: Alters urine color to bright orange or red.
  • Amitriptyline: Alters urine color to green-blue.
  • Levodopa: Alters urine color to dark brown or black.
  • Riboflavin (Vitamin B2): Alters urine color to bright yellow.

Diagnostic Testing and Diagnostic Procedures

• Bedside Sonography (Bladder Scanner):
  • Noninvasive, portable ultrasonic assessment utilized to calculate total intravesical bladder volume and post-void residual (PVR) volume remaining after voiding.
• Kidneys, Ureters, Bladder (KUB) Radiography:
  • Standard non-contrast X-ray image used to determine the size, anatomical shape, and exact position of the renal structures.
• Intravenous Pyelogram (IVP):
  • Intravenous administration of iodine contrast media combined with serial X-rays to visualize the renal ducts, renal pelvis, ureters, bladder, and urethra.
  • Critical Contraindication: Shellfish or iodine allergy strictly contraindicates the administration of IVP contrast media.
• Renal Scan:
  • Nuclear medicine procedure allowing detailed visual assessment of renal blood perfusion and functional kidney anatomy without using iodinated contrast media.
• Renal Ultrasound:
  • High-frequency sound wave imaging used to visualize gross renal anatomical structures and identify structural abnormalities.
• Cystoscopy:
  • Insertion of a flexible or rigid lighted cystoscope through the urethra to directly visualize, treat tissue, and harvest diagnostic tissue specimens from the bladder and urethral lumens.
• Urodynamic Testing:
  • Comprehensive evaluation of detrusor bladder muscle dynamics performed by instilling carbon dioxide ($CO_2$) or $0.9\%$ sodium chloride solution into the bladder to compare intravesical pressure readings directly against client-reported urinary sensations.

Clinical Interventions for Healthy Elimination and Intake & Output Monitoring

• Equipment Selection for Elimination:
  • Male client urinal.
  • Standard toilet, bedside commode, or bedpan.
  • Fracture Pan: Specially designed flat pan for clients restricted to the supine position or immobilized in full body or lower extremity casts.
  • Regular Bedpan: Designed for clients capable of elevating their hips and sitting upright.
• Nursing Actions for Promoting Voiding:
  • Assist clients into an upright sitting position whenever clinically feasible.
  • Ensure optimal personal privacy and grant uninterrupted, adequate time for voiding.
• Intake and Output (I&O) Measurement Procedures:
  • Measuring Equipment: Hard plastic urometer attached to an indwelling urinary catheter drainage system, graduated measuring cylinders, male urinals, or toilet collection hats.
  • Measurement Technique: Empty urine from bedpans, bedside commodes, or drainage bags directly into calibrated graduated containers; position collection hats beneath toilet seats to measure voided volumes; read volumetric side hashmarks on male urinals.
  • Critical Alarm Value: A sustained urine output of less than $30\,mL/\text{hr}$ for more than $2\,\text{hr}$ represents a critical clinical indicator of renal dysfunction or hypovolemia requiring immediate nursing intervention.

Specimen Collection Protocols

• Required Collection Equipment:
  • Specimen Containers: Non-sterile containers for routine urinalysis; sterile specimen containers for clean-catch midstream and catheter-derived specimens.
  • Antiseptic cleansing soap or solution with clean towels.
  • Clean personal protective gloves.
  • Official client diagnostic specimen labels.
  • Urine capture devices (catheter, urinal, toilet hat, commode bucket).
• Urinalysis (Random Non-Sterile Specimen):
  • Explain procedure steps clearly to the client.
  • Affix accurate client identification labels to the container and adhere to standard institutional facility policies for laboratory transfer.
• Clean-Catch Midstream Specimen for Culture and Sensitivity (C&S):
  • Educate the client on aseptic midstream capture technique.
  • Direct the client to perform thorough meatal cleansing with provided antiseptic wipes, initiate voiding into the toilet to flush the urethral meatus, and interrupt urine flow to capture a clean midstream sample into the sterile container.
• Catheter Urine Specimen for C&S:
  • Extract a sterile specimen directly from the designated sampling port of a straight or indwelling urinary catheter using strict surgical asepsis (sterile technique).
• Timed Urine Specimens (e.g., 24-Hour Collection):
  • Collect all urine produced over a designated duration (e.g., $24\,\text{hr}$).
  • Instruct the client to void and completely discard the very first voiding, noting this exact time as the formal start of the testing window.
  • Retain all subsequent urine voided throughout the full test duration. Store the collection container in a refrigerator or on ice, label properly, and transfer to the laboratory immediately upon conclusion.

Urinary Catheterization Procedures, Care, and Irrigation

• Catheter Sizing and Material Selection:
  • Pediatric Clients: $8\text{ to }10\text{ Fr}$.
  • Adult Female Clients: $14\text{ to }16\text{ Fr}$.
  • Adult Male Clients: $16\text{ to }18\text{ Fr}$.
  • Latex Hypersensitivity: Exclusively utilize pure silicone or Teflon-coated catheter products.
• Insertion Equipment and Technique:
  • Commercially packaged sterile catheterization kit equipped with a closed sterile drainage bag, cleansing soap/water, and dedicated specimen collection container for straight catheterization.
  • Explain the procedure, ensure privacy, and employ strict surgical asepsis throughout insertion.
• Closed Intermittent Irrigation:
  • Perform closed intermittent irrigation using correct sterile technique to maintain system sterility and clear intraluminal obstructions.
• Routine Indwelling Catheter Care:
  • Maintenance Equipment: Soap, warm water, washcloth, and clean gloves.
  • Cleansing Protocol: Wash the urethral insertion site and catheter tubing with mild soap and water at least three times daily and immediately following bowel movements.
  • System Patency Assessment: If the client expresses feelings of bladder fullness or abdominal distention, inspect tubing for structural kinks, twisting, or intraluminal sediment accumulation.
  • Drainage Bag Positioning: Maintain the collection drainage bag at a vertical position below the level of the bladder at all times to prevent gravitational reflux of unsterile urine.
• Condom Catheter Application:
  • Equipment: Gloves, external condom catheter sheath, elastic non-constricting adhesive tape, leg drainage bag or standard collection bag.
  • Application Protocol: Explain the procedure to the client and apply the sheath securely over the penile shaft using proper technique to avoid circulatory impairment.

Catheter-Associated Urinary Tract Infection (CAUTI) Prevention and Management

• Clinical Definition:
  • A urinary tract infection developing while an indwelling catheter is in place or occurring within $48\,\text{hr}$ following catheter discontinuation.
• Primary Risk Factors:
  • Indwelling catheterization.
  • Prolonged dwell time of indwelling urinary catheters.
  • Accidental or intentional opening of the closed urinary drainage circuit.
  • Unnecessary routine changes of indwelling catheters.
  • Frequent manual irrigation of indwelling catheters.
• Clinical Manifestations:
  • Standard Presentation: Urinary frequency, severe urgency, nocturia, flank pain, hematuria, cloudy urine, foul odor, and systemic fever.
  • Presentation in Older Adults: Acute onset of increased mental confusion, recent unexplained falls, sudden onset of urinary incontinence, loss of appetite (anorexia), fever, tachycardia, and hypotension.
• Nursing Interventions and Prevention Protocols:
  • Maintain strict aseptic technique during initial catheter insertion.
  • Prevent mechanical obstruction and gravitational backflow of urine through the catheter, drainage tubing, and collection bag.
  • Provide consistent perineal hygiene routinely and immediately following episodes of fecal soiling.
  • Conduct daily clinical assessments regarding the ongoing medical necessity for the indwelling catheter.

Classification, Assessment, and Care of Urinary Incontinence

• Clinical Significance:
  • Urinary incontinence is a major direct cause of skin breakdown, pressure injuries, falls, and bone fractures, particularly among older adults.
• Major Incontinence Classifications:
  • Stress Incontinence: Involuntary loss of small urine volumes caused by sudden increases in intra-abdominal pressure (laughing, sneezing, coughing, or heavy lifting) in the absence of detrusor muscle contraction. Occurs in females due to weak pelvic floor muscles following childbirth or menopause, and in males following urethral alterations post-prostatectomy.
  • Urge Incontinence: Inability to delay urine flow long enough to reach a toilet facility, caused by hypertonicity or overactivity of the detrusor muscle elevating bladder pressure. Triggers include localized bladder mucosal irritation from UTIs or overactive bladder syndrome.
  • Overflow Incontinence: Urinary retention secondary to bladder overdistention, manifesting as frequent involuntary leakage of small urine volumes due to mechanical outlet obstruction or detrusor muscle acalculia/hypotonia. Frequently stems from neurological disorders (spinal cord injury, multiple sclerosis) causing a neurogenic flaccid bladder, or benign prostatic hyperplasia.
  • Reflex Incontinence: Involuntary leakage of moderate urine volume occurring predictably without preceding warning due to detrusor hyperreflexia, usually resulting from spinal cord dysfunction or central nervous system impairment (stroke, multiple sclerosis, spinal cord lesions).
  • Functional Incontinence: Loss of urine stemming from non-genitourinary factors that physically, cognitively, or environmentally impede timely response to the urge to void.
  • Transient Incontinence: Reversible urinary loss resulting from temporary inflammation/irritation (active UTI), severe temporary cognitive impairment, acute systemic disease states (hyperglycemia), or pharmacologic administration (diuretics, anticholinergics, sedatives).
• Risk Factors:
  • Female sex.
  • History of multiparity and successive vaginal deliveries.
  • Natural physiological aging, chronic urinary retention, vesical spasms, renal disease, and chronic cystitis.
  • Neurological Disorders: Parkinson’s disease, cerebrovascular accident (CVA), spinal cord injury (SCI), multiple sclerosis (MS).
  • Pharmacotherapy: Diuretics, opioids, anticholinergics, calcium channel blockers, sedatives/hypnotics, adrenergic antagonists.
  • Obesity, confusion, dementia, physical immobility, depression, diabetes mellitus, chronic degenerative conditions.
  • Complications: Increased risk for secondary falls, fractures, severe pressure injuries, and clinical depression.
• Expected Clinical Findings:
  • Loss of urine when laughing, coughing, or sneezing.
  • Enuresis (involuntary nocturnal bed-wetting).
  • Involuntary bladder spasms.
  • Urinary retention.
  • Frequency, urgency, and nocturia.
• Laboratory Diagnostics:
  • Urinalysis and Urine Culture & Sensitivity (C&S): Identifies underlying UTIs via presence of RBCs, WBCs, and pathogenic microorganisms.
  • Blood Creatinine and Blood Urea Nitrogen (BUN): Assesses intrinsic renal function (elevated in renal impairment).
• Diagnostic Imaging and Functional Procedures:
  • Abdominal Ultrasound: Identifies structural bladder abnormalities and quantifies post-void residual urine.
  • Voiding Cystourethrography (VCUG): Evaluates vesical size, anatomical shape, pelvic support, dynamic function, urethral obstruction (prostate), and post-void residual urine.
  • Cystourethroscopy: Direct visualization of internal bladder structures.
  • Uroflowmetry: Measures volumetric flow rate and total completeness of bladder emptying.
  • Electromyography (EMG): Measures functional strength and contractile electrical activity of pelvic floor muscles.
• Comprehensive Nursing Interventions:
  • Establish a personalized, structured toileting schedule.
  • Monitor and increase fluid intake throughout daytime hours, restricting fluids prior to bedtime.
  • Identify and eliminate physical and environmental obstacles to toileting.
  • Supply absorbent incontinence garments.
  • Apply an external condom catheter device for male clients.
  • Avoid placing indwelling catheters unless medically indicated.
  • Provide prompt, meticulous hygiene care following incontinence episodes.
• Client Education:
  • Maintain regular, soft bowel movements to prevent impaction-driven bladder pressure.
  • Consciously attempt to empty the bladder completely during each voiding attempt.
  • Maintain a detailed incontinence voiding diary.
  • Pelvic Floor (Kegel) Exercises: Consciously contract pelvic muscles for a count of $10$, relax slowly for a count of $10$, and repeat in sets of $15$ repetitions performed sequentially in lying, sitting, and standing positions.
  • Bladder Compression Techniques: Perform Credé, Valsalva, double voiding, or splinting maneuvers to facilitate bladder emptying in reflex incontinence.
  • Dietary Restrictions: Eliminate caffeine and alcohol consumption to reduce detrusor irritation, diuresis, and urgency.
  • Vaginal Cone Therapy: Utilize weighted vaginal cones to strengthen pelvic floor musculature in stress incontinence.

Pharmacological Management of Urinary Disorders

• Antibiotic Agents:
  • Representative Drugs: Gentamicin, cephalexin, trimethoprim/sulfamethoxazole, ciprofloxacin.
  • Indication: Treatment of underlying bacterial urinary tract infections.
  • Nursing Action: Administer medications alongside food to attenuate gastrointestinal distress.
  • Client Education:
  • Antibiotic therapy may alter the odor of urine.
  • Complete the full prescribed course of antibiotics even if clinical symptoms resolve prematurely.
  • Consume trimethoprim/sulfamethoxazole with a full $8\,oz$ glass of water.
  • Trimethoprim/sulfamethoxazole and ciprofloxacin induce photosensitivity; strictly avoid direct sunlight exposure.
  • Monitor for loose, watery stools or generalized skin rashes and report findings to the provider immediately.
• Tricyclic Antidepressants:
  • Representative Drug: Nortriptyline.
  • Mechanism: Possesses anticholinergic properties that decrease detrusor contractions, relieving urinary incontinence.
  • Nursing Actions: Monitor for dizziness; evaluate baseline and standing blood pressure for orthostatic hypotension; DO NOT administer to clients concurrently taking monoamine oxidase inhibitors (MAOIs).
  • Client Education: Instruct clients to change body positions slowly when transitioning from lying to sitting or standing.
• Urinary Antispasmodics and Anticholinergic Agents:
  • Representative Drugs: Oxybutynin, dicyclomine.
  • Mechanism: Direct relaxation of detrusor smooth muscle, decreasing urgency and alleviating pain associated with neurogenic or overactive bladder.
  • Nursing Actions: Screen clients for a history of glaucoma, as these drugs increase intraocular pressure; monitor for dizziness, tachycardia, and acute urinary retention.
  • Client Education: Instruct client to report dysuria, cardiac palpitations, or severe constipation; educate that dizziness and xerostomia (dry mouth) are common side effects.
• Bladder Analgesic Agents:
  • Representative Drug: Phenazopyridine.
  • Mechanism: Local mucosal analgesic treating pain, burning, and discomfort associated with lower UTIs.
  • Nursing Actions: Clarify that the drug provides symptomatic discomfort relief but possesses no antimicrobial activity; monitor baseline Hgb and Hct for drops; contraindicated in clients with hepatic disorders or renal insufficiency.
  • Client Education: Administer medication with meals; inform that urine will turn a bright orange or red color; instruct to notify the provider immediately if scleral or cutaneous jaundice occurs (yellowing of skin, palms, soles, or mucous membranes).
• Hormone Replacement Therapy:
  • Clinical Status: Utilization remains controversial; functions by restoring pelvic vascularity and mucosal tissue integrity.

Therapeutic Programs, Surgical Interventions, and Post-Discharge Care

• Bladder-Retraining Program:
  • Clinical Goal: Increases vesical storage capacity and enhances the client's voluntary ability to suppress urinary urgency.
  • Patient Protocol: Void strictly at predetermined scheduled intervals; incrementally extend voiding intervals once the client remains continent for $3\,\text{days}$, working systematically toward an optimal $4\,\text{hr}$ voiding target; hold urine until scheduled voiding intervals; maintain accurate time logs; utilize deep breathing relaxation techniques; wear incontinence undergarments for safety; receive positive reinforcement for continent intervals.
• Urinary Habit Training:
  • Clinical Application: Targeted toward clients suffering from cognitive deficits.
  • Protocol: Establish a predictable voiding schedule matched strictly to the client's natural, individualized pattern of continent voiding.
• Intermittent Urinary Catheterization:
  • Clinical Application: Periodic bladder emptying to eliminate continuous static urine and reduce CAUTI risks relative to indwelling catheters; serves as a temporary measure for clients at risk for skin breakdown when alternative noninvasive strategies fail.
  • Nursing Management: Adjust catheterization frequency dynamically to keep total evacuated urine volume at or below $300\,mL$ per catheterization.
• Surgical Interventions for Stress Incontinence:
  • Procedures: Anterior vaginal repair, retropubic suspension, pubovaginal sling creation, or artificial urinary sphincter insertion.
  • Suprapubic Catheterization: Surgical insertion of a catheter directly through the lower abdominal wall above the pubic bone into the bladder, sutured securely. Tubing and drainage bag care matches indwelling urinary catheter protocols.
  • Catheter Removal Criteria: Suprapubic or urethral catheters remain in place until post-void residual (PVR) volumes consistently measure less than $50\,mL$.
  • Stabilization: Apply gentle traction with tape to stabilize catheter placement and prevent intravesical movement.
  • Nursing Actions: Monitor total output, urine color, sediment, and clinical manifestations of infection; maintain continuous tube patency; evaluate the client's capacity to perceive voiding urges.
  • Client Education: Instruct client on proper skin care surrounding the suprapubic insertion site, along with proper bag care and emptying procedures.
• Periurethral Collagen Injections:
  • Procedure: Direct local injection of collagen or silicone implants into periurethral wall tissues to elevate urethral resistance and impede involuntary leakage.
• Discharge Planning and Environmental Modifications:
  • Service Consults: Arrange home health services to supply intermittent catheters, portable bedside commodes, or elevated toilet seat risers.
  • Home Safety Modifications: Recommend installing sturdy bathroom handrails.
  • Health Teaching:
  • Maintain a daily fluid intake between $2\text{ to }3\,L$.
  • Adhere strictly to bladder retraining intervals.
  • Consume cranberry juice to reduce bacterial adherence and UTI risk.
  • Participate in a weight-reduction program if obese to alleviate mechanical stress incontinence.
  • Take prescribed incontinence medications reliably.
  • Perform self-intermittent catheterization as prescribed.
  • Express psychosocial feelings regarding incontinence.
• Complication Management:
  • Skin Breakdown: Results from chronic cutaneous exposure to acidic urine. Nursing actions: Keep skin continuously clean and dry, perform regular skin assessments, apply protective barrier creams, and implement a bladder-retraining program.
  • Social Isolation: Nursing actions: Provide discrete containment products (perineal pads, external catheters, adult garments) and offer empathetic emotional support.
