Genitourinary system

Emphasis on the necessity of a deep understanding of renal function in nursing practice.
- Encounter renal-related content daily, regardless of a nursing specialty (e.g., pediatrics, geriatrics, adult, family).
- Knowledge extends beyond test preparation for NCLEX; practical application is crucial.

Importance of urine collection in assessing renal function.
Methods of urine collection:
  - Clean Catch Method: Starts with initiating urine stream and capturing midstream urine.
  - Catheterization:
    - Use existing catheters or perform in/out catheterization as per facility protocols.
    - Documentation is key (clarity, color, presence of any abnormalities such as redness, swelling, tenderness, burning, discharge).

Tests include:
- Detection for nitrates (indicates bacterial presence) and white blood cells (pyuria).
- Culture and Sensitivity Test: Conducted if urinalysis indicates infection to identify bacteria and appropriate antibiotics.
Urine Specific Gravity (USG):
  - Normal range: $1.005$ to $1.030$ .
  - Values above $1.030$ may indicate concentrated urine and possible dehydration.
  - Early detection of kidney dysfunction is critical for intervention and patient safety.

Avoid nephrotoxic medications in cases of elevated USG:
- NSAIDs (e.g., ibuprofen, Aleve)
- Certain antibiotics (e.g., gentamicin, vancomycin)
Vulnerable populations: pediatrics and geriatrics, requiring special attention to hydration and renal function.

Measurement of GFR: Clearance of creatinine is indicative of kidney function.
  - Normal values: Male: $107$ - $139$ , Female: $87$ - $107$
  - Purpose: Access kidney function, monitor renal disease, calculate medication dosages, identify compromised perfusion.
  - Procedure: Start timing upon collection of the initial urine, discard the first void, refrigerate collection for 24 hours, and compare with blood serum samples.

Monitors renal function and detects damage, screens for acute kidney injury, and can stage chronic kidney disease.
- Increased Levels: Indicate impaired renal function; reference normal ranges from provided materials.

KUB (Kidneys, Ureters, Bladder): X-ray to visualize anatomy; detects radio opaque structures.
CT Scan: Identifies tumors, obstructions; requires consideration of contrast allergy (e.g., iodine, shellfish).
- Post-procedure fluid intake is crucial for flushing contrast from the kidneys.
IVP (Intravenous Pyelogram): Assess the urinary tract after contrast injection.
Cystoscopy: Visual examination of the bladder using a lighted scope; potential post-procedure complications discussed.

Defined as infections affecting the bladder and urethra.
Cystitis: Inflammation of the bladder; common symptom is urgency, frequency, and bladder pain.
Urethritis: Inflammation of the urethra.
- Complicated UTIs may lead to pyelonephritis and are linked to antibiotic resistance.
Risk Factors: Aging, obesity, diabetes, underlying structural issues, and urinary catheter use;
- Additional risk increases with bubble baths, pregnancy, and poor personal hygiene.

Lower UTI: Dysuria, increased frequency and urgency, hematuria, foul-smelling urine.
Upper UTI (pyelonephritis): Includes all lower symptoms plus fever, chills, flank pain, confusion (especially in older adults).

Diagnosis via urinalysis and culture sensitivity.
First-line Treatment: Antibiotics (e.g., Bactrim); urinary analgesics (e.g., phenazopyridine can change urine color).
Educational advice for patient hygiene practices and hydration.

Inflammation of the renal parenchyma; caused primarily by bacteria.
Symptoms include fever, chills, pyuria, flank pain, nausea, and malaise.
If untreated, it can cause severe complications like urosepsis.
Treatment Protocol: Outpatient antibiotics, hydration, monitoring for complications.

Definition: Solid lumps formed from crystals in the kidneys, varying sizes.
Symptoms: Severe pain (often referred to as the "kidney stone dance"), hematuria, nausea, and vomiting.
Diagnosis: Initially via urinalysis; advanced imaging via KUB or CT scan.
Management: Most stones pass spontaneously; larger stones may require lithotripsy or surgery.

Different types of stones require specific dietary modifications:
- Calcium Oxalate Stones: Reduce intake of calcium-rich foods (milk, cheese) and oxalate sources (spinach, nuts, tea).
- Uric Acid Stones: Avoid organ meats and shellfish; increase hydration.
Importance of educating patients on hydration and dietary adjustments.

Primary risk factor: Cigarette smoking (over 50% associated).
Symptoms include painless hematuria and can lead to various complications.
Diagnosed through cystoscopy, confirmed via imaging studies.
Treatment typically involves surgical resection followed by chemotherapy/radiation.

Surgical diversions redirect urine flow in conditions where bladder function is impaired.
Common procedures include ileal conduit creation post-cystectomy; management of stoma and monitoring for complications are key post operative tasks.
- Normal findings include mucus in urine but vigilant observation for signs of infection is essential.

Surgical removal of a kidney; information on post-operative care includes monitoring urine output and educating patients on lifestyle modifications and symptom reporting.
