Study Notes

Urinary System Changes in Aging

Bladder Changes:
- Elasticity decreases making the bladder less stretchy.
- Bladder loses holding capacity, leading to more frequent urination and nocturia (waking up during the night to urinate).
- Bladder muscles weaken, contributing to stress incontinence (leakage during coughing, sneezing, or exercise).
- Slower urine flow due to age-related changes.
Kidney Changes:
- Nephron count decreases, impacting overall kidney function.
- Kidney tissues thicken, potentially accumulating fatty deposits.
- Reduced blood flow to kidneys due to changes in blood vessel elasticity and decreased cardiac output.
Urethral Changes:
- Urethra can become blocked, leading to urinary retention.
  - In women, weakened muscles cause bladder or vaginal prolapse (falling out of position).
  - In men, an enlarged prostate gland can block the urethra.

Common Urinary Problems in Older Adults

Bladder control issues:
- Urinary incontinence (leakage)
- Urinary retention (inability to completely empty the bladder)
Urinary Tract Infections (UTIs):
- Increased risk due to changes in the urinary tract, weakened immune system, and urinary retention.
Bladder and Kidney Stones:
- Increased risk with age, leading to pain, urinary symptoms, and potential urinary tract obstruction.
Chronic Kidney Disease (CKD):
- Aging is a major risk factor, often because of pre-existing conditions like diabetes or high blood pressure.
Pelvic Organ Prolapse in women:
- Weakened pelvic floor muscles cause the bladder, uterus, or rectum to descend, leading to urinary symptoms including incontinence.
Benign Prostatic Hyperplasia (BPH) in Men:
- Enlargement of the prostate gland, often occurring with aging.
- Causes urethral obstruction, leading to difficulties urinating, weak urine flow, frequent urination, and incomplete bladder emptying.

Management of Urinary System Changes

Pelvic muscle exercises (Kegel exercises):
- Strengthen bladder control by exercising the muscles used to stop urination.
Bladder retraining:
- Gradually increasing the time between bathroom visits to help control urgency incontinence.
Lifestyle changes:
- High-fiber diet to prevent constipation which can worsen bladder control issues.
Incontinence products:
- Pads, adult diapers, and protective clothing to manage incontinence symptoms and maintain dignity.
Mental health and support:
- Address anxiety or depression related to urinary issues.
- Provide counseling or support groups for coping strategies.
- Caregiver support for frail or cognitively impaired individuals.
Education and support:
- Provide education and support to the individual and their caregivers about the condition and management.
- Offer psychosocial support for emotional and psychological aspects of urinary problems.

Diagnostic Tests

Urinalysis:
- Comprehensive analysis of urine to detect:
  - Infections (UTIs)
  - Kidney diseases
  - Metabolic disorders
  - Presence of blood, protein, glucose, or ketones.
Urine Culture:
- Identifies specific bacteria or fungi causing UTI.
Blood Urea Nitrogen (BUN) and Creatinine:
- Measure waste products in the blood to assess kidney function.
Ultrasound:
- Creates images of the kidneys, bladder, and urinary tract to detect abnormalities like stones, tumors, or structural issues.
Cystoscopy:
- A thin tube with a camera is inserted through the urethra into the bladder to visualize the bladder lining.
