Study Notes on Urologic Disorders from Medical-Surgical Nursing

Overview of Urologic Disorders

Learning Objectives

  • Examine the signs and symptoms of selected urologic inflammatory disorders (e.g., cystitis, urethritis, pyelonephritis) and nursing interventions for these patients.
  • Explain nursing management for patients with acute or chronic glomerulonephritis.
  • Analyze types of patient conditions that create a risk for acute renal failure (ARF).
  • Compare the needs of patients on long-term hemodialysis with patients who use peritoneal dialysis.
  • Identify the benefits and problems associated with kidney transplantation.

Cystitis

Etiology and Pathophysiology

  • Major pathogen: Escherichia coli.
  • Associated with female urethra and often termed "honeymoon" cystitis.
  • Estrogen depletion in aging leads to:
    • Structural atrophy.
    • Urinary dysfunction, contributing to urinary stasis.

Signs and Symptoms

  • Painful urination (dysuria).
  • Frequent, urgent urination.
  • Low back pain.
  • Tendency to recur with:
    • Less acute symptoms: fatigue, anorexia, constant bladder pressure.
  • Confusion in older adults with signs of infection:
    • Cloudy urine.
    • Hematuria (blood in urine).

Treatment and Nursing Management

  • Antibiotics: Primary mode of treatment.
  • Topical estrogen for postmenopausal women to manage symptoms.
  • Encourage fluid intake: 8 to 12 large glasses unless contraindicated.
  • Dietary modifications:
    • Cranberry juice to alter urinary pH.
  • Comfort measures:
    • Sitz baths and hot water bottles.
  • Educate on prevention of urinary tract infections (UTIs).
  • Consider Vitamin C supplements to acidify urine and prevent UTIs.

Urethritis

Etiology and Pathophysiology

  • Pathogens:
    • Gonococcus (gonorrhea).
    • Herpes virus.
    • Nonspecific urethritis.
  • Causes:
    • Childbirth trauma.
    • Chemical irritation.

Signs and Symptoms

  • Burning and itching at the urethra.
  • Frequency and painful urination.
  • Purulent discharge if gonorrhea is present.

Diagnosis

  • Based on symptoms and patient history, particularly regarding sexually transmitted infections (STIs).
  • Culture and sensitivity of urine to identify organisms and rule out STIs.

Treatment and Nursing Management

  • Similar management to cystitis.
  • Monitor for potential gonorrheal infection and educate on prevention of spreading the infection.

Pyelonephritis

Etiology and Pathophysiology

  • Acute pyelonephritis: associated with urine stasis.
  • Chronic infection leads to scar tissue development.

Signs and Symptoms

  • Acute: fever, chills, headache, malaise, nausea, vomiting, flank pain radiating to the thigh and genitalia.
  • Chronic: gradual scarring, weight loss, low-grade fever, weakness.

Diagnosis

  • Conduct urine culture and sensitivity tests.
  • Perform imaging:
    • Kidneys, ureter, bladder (KUB) radiography.
    • Intravenous pyelogram (IVP) for obstruction assessment.

Treatment

  • Prompt treatment is essential with:
    • Antibiotics, analgesics, antipyretics.
    • Correct obstructions, such as stone removal.
    • Bed rest necessary for patient comfort.

Glomerulonephritis

Acute Glomerulonephritis

Etiology and Pathophysiology
  • Commonly associated with beta-hemolytic streptococcal infection leading to an antigen-antibody reaction.
Signs and Symptoms
  • Sudden onset of fever, chills, flank pain.
  • Swelling (edema) around the eyes and hypertension.
  • Urinalysis reflects:
    • Smoky urine, presence of red blood cells, protein, and increased specific gravity.
Treatment
  • Initial therapy includes IV methylprednisolone and cyclophosphamide.
  • Dietary instructions:
    • Sodium-restricted and low-protein, high-carbohydrate diet.
  • Plasmapheresis may be necessary for autoimmune disorders.
Nursing Management
  • Assess for edema signs indicative of cardiac failure.
  • Ensure bed rest until resolved hematuria and hypertension.
  • Administration of antihypertensives and diuretics as necessary.

Chronic Glomerulonephritis

Etiology and Pathophysiology
  • Can develop rapidly or progress slowly.
  • Associated with renal atrophy leading to decreased functional nephrons and eventual renal failure.
Signs and Symptoms
  • Generalized edema, headache (often hypertension-related), fatigue, weight loss, irritability, nocturia.
  • Urinalysis shows proteinuria and urinary casts.
Diagnosis
  • Utilize routine examinations:
    • Retinal hemorrhage assessment, tests for BUN, creatinine, electrolytes.
Treatment
  • Involves management of symptoms and may require dialysis or kidney transplant in advanced stages.

Nephrotic Syndrome

Signs and Symptoms

  • Characterized by:
    • Proteinuria, hyperlipidemia, hypoalbuminemia.
    • Severe edema, especially around the eyes (facial and periorbital) and lower extremities.

Diagnostic Tests

  • Urinalysis to monitor proteins and lipids.
  • Renal biopsy may be necessary for definitive diagnosis.

Treatment

  • Dietary management includes adequate protein intake with low-fat, low-sodium diet.
  • Medications: diuretics, antibiotics, corticosteroids, and cyclophosphamide.

Nursing Management

  • Monitor intake and output, daily weights, and provide skin care.
  • Encourage compliance with diet and medication regimens.

Renal Stones

Etiology and Pathophysiology

  • Formation due to:
    • Urinary stasis, dehydration, and certain metabolic conditions like obesity and gout.
  • Types:
    • Calcium oxalate (most common), calcium phosphate, uric acid, struvite, cystine stones.
Signs and Symptoms
  • Severe flank pain that radiates to the groin.
  • Nausea and vomiting accompanying obstruction.
Diagnosis
  • Conduct urinalysis, KUB, and IVP, along with serum levels of calcium, uric acid, and cystine.
Treatment
  • Manage pain with opioids or NSAIDs.
  • Increase fluid intake to flush stones, consider procedures like extracorporeal shockwave lithotripsy (ESWL) or surgical options for removal.
Nursing Management
  • Monitor for infection, maintain fluid intake, and support ambulation post-treatment.

Trauma to Kidneys and Ureters

Etiology and Pathophysiology

  • Caused by blunt trauma (e.g., from vehicles) or penetrating injuries.

Signs and Symptoms

  • Massive hemorrhage, hematuria, abdominal and flank pain, may indicate kidney damage.

Diagnosis and Tests

  • Use urinalysis, hemoglobin levels, BUN, and imaging studies (KUB, CT) to assess damage.

Treatment

  • Bed rest for minor injuries; nephrectomy for severe damage.

Nursing Management

  • Pre- and postoperative care focused on monitoring for shock, urinary output, and signs of bleeding.

Bladder Trauma

Etiology and Pathophysiology

  • Resulting from violent injuries, particularly when the bladder is distended.

Signs and Symptoms

  • Painful hematuria, inability to void, abdominal tenderness.

Diagnosis and Treatment

  • Cystography or CT for diagnosis; suprapubic cystostomy for ruptured bladders.

Nursing Management

  • Emphasize careful monitoring post-surgery, including attention to drains, skin integrity, and prevention of complications.

Cancer of the Bladder

Etiology and Pathophysiology

  • Associated with risk factors: smoking, urban living, occupational exposure.

Signs and Symptoms

  • Hematuria and voiding difficulties.

Diagnosis

  • Utilize IVP, cystoscopy, or biopsy of tumors for definitive diagnosis.

Treatment

  • May involve surgery (cystectomy) and chemotherapy treatments.

Kidney Cancer

Etiology and Pathophysiology

  • Risk factors include smoking and environmental exposure.

Symptoms and Diagnosis

  • Hematuria, abdominal mass, flank pain; diagnosis via renal angiogram or imaging.

Treatment

  • Nephrectomy and chemotherapy for advanced cases.

Acute Renal Failure (ARF)

Etiology

  • Common causes include prerenal conditions like hypovolemic shock, intrarenal causes like acute tubular necrosis, and postrenal obstructions.

Signs and Symptoms

  • Changes in urine output; electrolytic, fluid, and acid-base imbalances.

Diagnosis

  • Urinalysis, serum tests (creatinine, BUN), and imaging.

Treatment

  • Address underlying causes, manage complications, consider dialysis as necessary.

Chronic Renal Failure (CRF)

Etiology

  • Progressive loss of kidney function due to conditions like hypertension and diabetes.

Signs and Symptoms

  • Uremia with polyuria, then oliguria/anuria; systemic effects emerge as renal impairment worsens.

Diagnosis and Treatment

  • Diagnosed through laboratory tests (creatinine, electrolytes); treatment includes dialysis or renal transplantation.

Nursing Considerations

  • Promote care and adherence to treatment regimens to optimize patient health outcomes during chronic disease management.
