Renal Urologic Problems

Diagnostic Studies for Renal Urologic Problems
  • Importance of Diagnostic Studies: Essential for assessing kidney function and identifying conditions.
  • Serum Creatinine:
    • Indicator of kidney function.
    • Mainly derived from muscle and protein breakdown.
    • Constant in older adults unless kidney disease is present.
  • Blood Urea Nitrogen (BUN):
    • Indicates breakdown of protein in the liver.
    • Affected by factors like dehydration and medication.
    • Elevated levels suggest kidney disease.
  • Urinalysis:
    • Includes culture and sensitivity to identify bacteria.
    • Determines appropriate antibiotic treatment.
  • 24-Hour Urine Collection:
    • Measures levels of various substances (e.g., creatinine, proteins).
    • Helps assess renal function.
  • Imaging Studies (CT, Ultrasound, X-Ray):
    • Identify obstructions, calculate kidney size, detect masses.
    • KUB (Kidneys, Ureters, Bladder) x-ray visualizes structures and detects calcium deposits.
Anatomy of the Urinary Tract
  • Ureters:
    • Tubes carrying urine from kidneys to bladder via peristaltic movements.
  • Bladder:
    • Collects urine; sends signals to the brain when full.
  • Urethra:
    • Tube leading from bladder to outside of the body (length differences in males and females).
    • Related to higher UTI rates in females.
  • Urinary Tract Infections (UTIs):
    • Caused by microorganisms entering the urinary tract, leading to inflammation (Cystitis is inflammation of the bladder).
    • Severe complications include sepsis and pyelonephritis (kidney infection).
UTI Symptoms and Types
  • Common Symptoms: Pain with urination, frequency, urgency, foul odor, cloudy urine, and flank pain.
  • Pathogens:
    • Most are E. Coli and Candida (especially with Foley catheters).
  • Complicated vs Uncomplicated UTIs:
    • Uncomplicated: Usually bladder only.
    • Complicated: Structural or functional abnormalities warranting further investigation.
Assessment and Diagnosis of UTIs
  • Assessment: Use COCA (Color, Odor, Consistency, Amount) for urine assessment.
    • Urinalysis and urine cultures to confirm infection.
  • Elderly Symptoms of UTI: May present confusion, incontinence, and decreased appetite.
Management of UTIs
  • Fluids: Increase intake to 3 liters/day to help flush bacteria.
  • Antibiotics: Prescribed based on sensitivity.
    • Empirical therapy for uncomplicated UTIs.
  • Patient Education: Front-to-back wiping, avoiding irritants (e.g., citrus, bubble baths).
Kidney Problems: Pyelonephritis
  • Definition: Inflammation/infection of renal parenchyma and collecting system that often arises from a UTI.
  • Causes: Bacterial infection (e.g., E. Coli) or structural problems like vesicoureteral reflux.
  • Symptoms: Fever, chills, flank pain, malaise, vomiting, dysuria.
  • Diagnostics: Urinalysis, elevated creatinine/BUN, signs of casts in urine indicate kidney infection.
  • Treatment: Fluids, antibiotics, and managing kidney function.
Glomerulonephritis
  • Definition: Inflammation of the glomeruli due to immune responses affecting filtration.
  • Acute vs Chronic:
    • Acute: Sudden onset, potentially reversible.
    • Chronic: Prolonged, leads to renal failure.
  • Symptoms: Edema, hypertension, oliguria, dark/foamy urine.
  • Management: Symptom relief, possible fluid/sodium restriction, treat underlying causes, monitor electrolytes.
Nephrotic Syndrome
  • Definition: Increased permeability of the glomerular membrane leading to protein loss in urine.
  • Symptoms: Edema, hypoalbuminemia, hypertension, foamy urine.
  • Management: Corticosteroids, medications for cholesterol, and controlling underlying conditions.
Urinary Calculi (Kidney Stones)
  • Definition: Stones in the urinary tract that may obstruct urine flow.
  • Types: Calcium oxalate, struvite, uric acid, cystine stones.
  • Symptoms: Severe pain (renal colic), hematuria, nausea, urinary obstruction.
  • Diagnosis: Urinalysis, imaging (CT/Ultrasound), stone retrieval for analysis.
  • Management: Increase fluid intake, pain management, possible surgical intervention for larger stones.
Bladder Cancer
  • Risk Factors: Male gender, age, smoking, carcinogen exposure.
  • Symptoms: Hematuria, urgency, frequency.
  • Diagnosis: Intravenous pyelogram (IVP).
  • Treatment: Surgical tumor removal, chemotherapy, radiation as needed.
Postoperative Management and Monitoring of Urinary Diversion
  • Observations: Pain management, urinary output characteristics, stoma health.
  • Nursing Interventions: Assess for complications like infection or impaired blood flow, promote skin care, and provide emotional support.
