    Study Notes

    Urinary Tract Infections (UTIs)

    • The second most common reason for seeking healthcare.
    • A frequent source of nosocomial infections (hospital-acquired).
    • UTIs involve bacteria entering the urinary tract, most commonly from the digestive tract, and multiplying.
    • Escherichia coli is the primary culprit in most cases.
    • Lower UTIs:
      • Bacterial cystitis (bladder infection).
      • Bacterial prostatitis (inflammation of the prostate).
      • Bacterial urethritis (inflammation of the urethra).
    • Upper UTIs:
      • Pyelonephritis: acute and chronic (kidney infection).
      • Interstitial nephritis (inflammation of the kidney tissue).
      • Renal abscess and perirenal abscess (infections in the kidney or surrounding area).
    • Urethrovesical reflux: backflow of urine from the urethra into the bladder.
    • Routes of infection:
      • Ascending infection [transurethral]: bacteria travel up the urethra, often from fecal contamination.
      • Hematogenous spread: bacteria enter through the bloodstream from a distant site of infection.
      • Direct extension: bacteria reach the urinary tract through a fistula (abnormal connection) from the intestine.
    • Factors contributing to UTIs:
      • Function of glycosaminoglycan (GAG), a protective substance in the bladder lining.
      • Urethrovesical reflux: backflow of urine from the urethra into the bladder.
      • Ureterovesical reflux: backflow of urine from the bladder into the ureter.
      • Uropathogenic bacteria: bacteria that cause UTIs.
      • Shorter urethra in women makes them more susceptible to UTIs.
    • Increased risk factors for UTIs:
      • Women are more prone to UTIs than men.
      • Obstructive conditions of the urinary tract, such as kidney stones.
      • Medical conditions causing incomplete bladder emptying, such as spinal cord injury (SCI).
      • Immunosuppressed individuals: those with AIDS, diabetes, or organ transplants.
      • Sexually active females.
      • Males with enlarged prostate, leading to incomplete bladder emptying.

    Clinical Manifestations

    • Lower UTI (cystitis):
      • Pain and burning on urination (dysuria).
      • Frequent urination, urgency, nocturia (getting up at night to urinate), incontinence, suprapubic or pelvic pain.
      • Hematuria (blood in urine) and back pain are possible.
    • Upper UTI (pyelonephritis):
      • Chills, fever, flank (side of the back) or low back pain.
      • Nausea and vomiting, headache, malaise (general discomfort), and painful urination.
    • Complicated UTI:
      • Often occurs in individuals with indwelling catheters.
      • May be asymptomatic, but can progress to sepsis (blood infection) and shock.
      • Caused by a wider range of bacteria.
      • Individuals with lower resistance and delayed treatment response.

    Gerontologic Considerations

    • Older adults are at increased risk of UTIs.
    • Atypical symptoms may occur in older adults, such as:
      • Anorexia (loss of appetite).
      • Fatigue & weakness.
      • Changes in mental status (confusion).

    Assessment and Diagnosis

    • Subjective assessment: Patient history, including symptoms, medical/surgical history, medications, and lifestyle.
    • Objective assessment:
      • WBC dipstick: Leukocyte esterase test and nitrite testing; a positive result indicates pyuria (WBCs in the urine).
      • Urinalysis: examines urine for signs of infection, such as WBCs and bacteria.
      • Urine culture and sensitivity (C&S): collected from a midstream urine sample; identifies the specific microorganism causing the infection and appropriate antibiotics.
    • Diagnostic tests:
      • Ultrasound examination: evaluates kidney and bladder problems.
      • Fluoroscopic study: identifies physical issues contributing to UTIs in children.
      • Intravenous pyelogram (IVP): X-rays using contrast dye to visualize abnormalities in the urinary tract.
      • Cystoscopy: thin, flexible tube with a camera inserted into the bladder to detect abnormalities.
      • CT scan: provides detailed 3D images of the urinary tract.

    Pharmacological Treatments

    • Antibacterial agents:
      • Ampicillin or amoxicillin: common penicillin-based antibiotics.
      • Nitrofurantoin (Macrodantin, Furadantin): bacteriostatic agent (slows bacterial growth) that works specifically in the urinary tract.
      • Ciprofloxacin: bactericidal (kills bacteria) antibiotic effective against gram-negative bacteria.
    • Other antibiotics:
      • Cephalosporins: bactericidal antibiotics.
      • Trimethoprim/sulfamethoxazole (Co-trimoxazole, Bactrim, Septra, Septra DS): common combination antibiotic.
    • Urinary analgesic:
      • Phenazopyridine (Pyridium): relieves pain and burning associated with UTIs.

    Interventions

    • Prevention:
      • Avoid indwelling catheters whenever possible.
      • Maintain proper catheter hygiene.
      • Practice correct personal hygiene.
    • Management:
      • Take medications as prescribed: antibiotics, analgesics, and antispasmodics.
      • Increase fluid intake.
      • Avoid urinary irritants (coffee, tea, colas, alcohol).
      • Urinate frequently.

    Urinary Incontinence

    • Urinary incontinence is a prevalent, underreported condition that can significantly impact quality of life.
    • It is not an inevitable consequence of aging.
    • Types:
      • Stress incontinence: leakage with physical exertion, coughing, sneezing, or laughing.
      • Urge incontinence: sudden, strong urge to urinate that is difficult to control.
      • Functional incontinence: inability to reach the toilet due to physical limitations or cognitive impairment.
      • Iatrogenic incontinence: leakage caused by medication or medical procedures.
      • Mixed incontinence: a combination of different types of incontinence.
      • Reflex incontinence: involuntary leakage due to neurological damage.
      • Overflow incontinence: continuous leakage from a full bladder that cannot empty completely.
    • Patient teaching:
      • Urinary incontinence is treatable and not inevitable.
      • Management requires time and collaboration.
      • Use a voiding log or diary to track voiding patterns.
      • Engage in behavioral interventions, such as bladder training and pelvic floor exercises.
      • Understand and adhere to medication instructions.
      • Implement strategies for promoting continence, such as avoiding caffeine and bladder irritants.
    • Causes of transient incontinence:
      • Atrophic vaginitis, urethritis, prostatitis.
      • Delirium or confusion.
      • Excessive urine production.
      • Limited or restricted physical activity.
      • Medications.
      • Depression.
      • Constipation.
      • UTIs.

    Urinary Retention

    • Inability of the bladder to empty completely.
    • Residual urine: amount of urine remaining in the bladder after voiding.
    • Causes:
      • Age: decreased detrusor muscle activity leads to higher residual urine in older adults.
      • Diabetes, prostate enlargement, pregnancy, neurologic disorders, and certain medications.
    • Assessment: nursing measures to facilitate voiding, such as bladder scanning and monitoring residual urine volume.

    Neurogenic Bladder

    • Dysfunctional bladder due to neurological damage, leading to urinary incontinence.
    • Causes: spinal cord injury, tumor, herniated vertebral disk, multiple sclerosis, congenital disorders, diabetes, or infection.
    • Types:
      • Spastic bladder: involuntary bladder contractions and frequent, uncontrolled leakage.
      • Flaccid bladder: weakened bladder muscle, leading to incomplete emptying and retention.
    • Assessment and diagnostic findings: neurological examination, urodynamic studies, and imaging tests.
    • Complications:
      • UTIs, renal damage, and hydronephrosis (swelling of the kidneys).
    • Medical management: medications, bladder training, and intermittent catheterization.
    • Nursing management: promoting bladder emptying, preventing UTIs, assisting with catheterization, and providing emotional support.

    Catheterization

    • Indications:
      • Indwelling catheter: long-term bladder drainage.
      • Suprapubic catheter: inserted into the bladder through the abdomen.
    • Nursing considerations:
      • Preventing infection: maintaining strict aseptic technique during catheterization, monitoring for signs of infection, and providing regular catheter care.
      • Assisting with self-catheterization: teaching and supporting individuals with self-catheterization techniques.

    Urolithiasis and Nephrolithiasis

    • Calculi (stones): formations in the urinary tract or kidneys.
    • Pathophysiology:
      • Causes are often unclear.
    • Manifestations:
      • Depend on the location, presence of obstruction, or infection.
      • Pain and hematuria (blood in urine).
    • Diagnosis:
      • X-ray, blood chemistries, urine tests, and stone analysis.
      • Strain all urine to collect any stones.
    • Types:
      • Nephrolithiasis: stones found in the kidneys.
      • Ureterolithiasis: stones found in the ureters.
      • Urolithiasis: stones occurring anywhere in the urinary tract.
    • Incidence: Most stones develop in the kidneys. Higher prevalence in men aged 40-60.
    • Pathophysiology:
      • Lack of substances that prevent crystallization in the urine.
      • Dehydration can increase the risk of stone formation.
    • Factors contributing to stone formation:
      • Infection: particularly UTIs.
      • Urinary stasis (urine staying in the bladder for too long).
      • Immobility.
      • High calcium concentration in the blood and urine.
    • Types of stones:
      • Calcium stones (70%): the most common type.
      • Struvite stones: associated with UTIs and ammonia-rich urine.
      • Uric acid stones: common in individuals with gout.
      • Cystine stones: rare (<1%), caused by a genetic disorder.
    • Predisposing factors:
      • Kidney diseases, such as polycystic kidney disease.
      • Inflammatory bowel disease (IBD) and ileostomy.
      • Certain medications.
