Study Notes

Urinary Tract Infections (UTIs)

Most UTIs affect the lower urinary tract, including the urethra, bladder, and prostate gland.
Women are more susceptible to UTIs than men due to anatomical differences.
Possible signs and symptoms include:
- Strong, persistent urge to urinate
- Burning sensation during urination
- Frequent small urine passage
- Cloudy urine
- Blood in urine (red, bright pink, or cola-colored)
- Strong-smelling urine
- Pelvic pain, especially in women

Risk Factors for UTIs

Incomplete bladder emptying and obstructed urinary flow increase risks.
Conditions leading to immunosuppression (e.g., weakened immune system) heighten susceptibility.
Urinary tract instrumentation can introduce pathogens.
Inflammation of the urethral mucosa contributes to risk.
Specific conditions such as diabetes, pregnancy, neurologic disorders, and certain anatomical anomalies can predispose individuals to UTIs.

Classification of UTIs

UTIs are classified into:
- Lower UTIs (e.g., urethritis, cystitis, prostatitis)
- Upper UTIs (e.g., pyelonephritis)
Uncomplicated UTIs typically occur in otherwise healthy individuals, while complicated UTIs may arise in patients with urologic abnormalities or after catheterization.

Mechanisms Maintaining Bladder Sterility

Urethra serves as a physical barrier against pathogens.
Continuous urine flow prevents infection.
Proper function of the ureterovesical junction helps maintain sterility.
Glycosaminoglycan (GAG) proteins create a hydrophilic barrier against bacteria.

Complications of UTIs

Chronic kidney injury can result from untreated UTIs.
Pregnant women may face risks of low birth weight or premature births.
Recurrent urethritis can cause urethral strictures in men.
Potential progression to urosepsis, a severe infection requiring immediate medical attention.

Pyelonephritis

A severe infection that affects one or both kidneys, characterized by inflammation of the renal pelvis and surrounding structures.
Causes include the upward movement of bacteria or from systemic infection.
Risk factors include urinary obstruction from stones, tumors, or benign prostatic hyperplasia.

Clinical Manifestations of Pyelonephritis

Acute pyelonephritis exhibits symptoms like fever, chills, flank pain, and leukocytosis.
Chronic pyelonephritis may cause fatigue, headache, poor appetite, excessive thirst, and weight loss if symptomatic.

Diagnostic Findings

Urinalysis shows excess white blood cells and bacteria.
Urine culture helps identify the specific bacteria causing infection.
Imaging methods such as CT scans or kidney ultrasounds assess for abscesses and blockages.

Adult Voiding Dysfunction

Types of urinary incontinence include:
- Stress incontinence: involuntary urine loss due to pressure (coughing, sneezing).
- Urge incontinence: loss associated with a strong urge to void.
- Functional incontinence: intact lower urinary function impaired by cognitive or physical limitations.
- Iatrogenic incontinence: urine loss due to medication effects.
- Mixed incontinence: combination of urge and stress incontinence.

Management of Incontinence

Behavioral Therapy: Involves fluid management, establishing voiding schedules, and bladder training exercises.
Pharmacologic Therapy: Anticholinergics, tricyclic antidepressants, pseudoephedrine (for retention), and hormone therapy can be effective.
Surgical Management: Procedures typically focus on bladder support and stabilization, including anterior vaginal repair and retropubic suspension.

Nursing Management

Emphasizes fluid monitoring and adequate hydration (3-4 L/day).
Health education on infection prevention, proper hygiene, and adherence to treatment plans.
