Urological Problems Lecture Prep and Study Guide

Topics Covered

  • Obstructive Urologic Disorders

  • Nephrolithiasis

  • Infectious Urinary Tract Disorders
      - Upper UTI

  • Related Pharmacotherapy

Study Guide/Objectives for After Class

  • Differentiate between:
      - Obstructive Urologic Disorders
      - Nephrolithiasis
      - Infectious Urinary Tract Disorders
      - Based on:
        - Pathophysiology
        - Clinical Presentation
        - Risk Factors

Nephrolithiasis

  • Describe:
      - Causes
      - Types
      - Clinical Manifestations

  • Factors contributing to stone formation

Urinary Tract Infections

  • Distinguish between:
      - Lower UTI
      - Upper UTI

  • Emphasis on recognizing signs and complications of upper UTIs, such as Pyelonephritis.

  • Identify:
      - Appropriate diagnostic tests:
        - Urinalysis
        - Urine Culture
        - Imaging
        - Labs
      - Interpret key findings

Pharmacologic Management

  • Explain:
      - Pharmacologic management of obstructive and infectious urinary tract disorders
      - Medications to include:
        - Antibiotics
        - Analgesics
        - Adjunct Medications
      - Focus on:
        - Indications
        - Adverse Effects

Clinical Features Matching Exercise

  • Match each clinical feature (A–O) with the correct condition:
    1 = Upper UTI (Pyelonephritis)
    2 = Lower UTI (Cystitis/Urethritis)
    3 = Nephrolithiasis (Kidney Stones)

Clinical Features List

  • Flank pain

  • Dysuria

  • Fever and chills

  • Hematuria

  • Costovertebral angle (CVA) tenderness

  • Urinary urgency and frequency

  • Nausea and vomiting

  • Severe, colicky pain radiating to the groin

  • Cloudy or foul-smelling urine

  • High white blood cell count

  • Pain worsens in waves

  • Suprapubic discomfort

  • Often caused by obstruction of urine flow

  • Can progress to sepsis if untreated

  • Crystals seen on urinalysis

Clinical Scenarios and Pharmacologic Needs

  1. Scenario: A patient admitted to the emergency department with severe flank pain radiating to the groin is diagnosed with acute nephrolithiasis.
       - Anticipated medication order for managing priority pharmacologic need:
         - A. Oral acetaminophen every 6 hours
         - B. IV morphine or hydromorphone
         - C. Oral allopurinol
         - D. Oral hydrochlorothiazide

  2. Scenario: A patient with a history of recurrent calcium oxalate kidney stones inquires about medication to prevent future stone formation.
       - Most appropriate response by the nurse:
         - A. “Antibiotics are prescribed long term to dissolve calcium stones.”
         - B. “Allopurinol is used to reduce calcium levels in the urine.”
         - C. “Thiazide diuretics decrease urinary calcium excretion.”
         - D. “Opioid analgesics prevent stone formation by relaxing the ureter.”

  3. Scenario: A 28-year-old female presents with dysuria, urinary frequency, and suprapubic discomfort. She is afebrile, denies flank pain, and has no significant past medical history. A urine dipstick is positive for leukocyte esterase and nitrites.
       - Most appropriate treatment for this patient:
         - A. Intravenous vancomycin for 14 days
         - B. Oral bactrim for 5 days
         - C. Oral acyclovir for 7-10 days
         - D. Immediate CT scan followed by surgical intervention
