Nephrolithiasis

Nephrolithiasis is a common urological disorder characterized by the formation of crystalline mineral deposits (calculi) within the renal pelvis and tubular system. These stones can cause severe pain, urinary obstruction, and infection.

Nephrolithiasis is caused by the supersaturation of urine with stone-forming salts. Contributing factors include:

• Dehydration: Low fluid intake increases solute concentration.


• Dietary factors: High sodium, animal protein, and oxalate intake.


• Metabolic disorders: Primary hyperparathyroidism, gout, renal tubular acidosis.


• Genetic mutations: Cystinuria (SLC3A1/SLC7A9 mutations).

The process initiates with urinary supersaturation, leading to solute precipitation and crystal nucleation. Crystals grow, aggregate, and deposit on the renal papillary epithelium (Randall's plaques). Over time, these calcifications grow into calculi that can detach, causing mechanical obstruction and spasms within the ureter.

• Prevalence: Lifetime risk is approximately 12% for men and 6% for women.
• Age/Gender: Peak incidence occurs between 20 and 50 years; historically males are more affected, though the gender gap is closing.

• Chronic dehydration
• Family history of urolithiasis
• Obesity and metabolic syndrome
• Inflammatory bowel disease (causes hyperoxaluria)
• Anatomical renal abnormalities (e.g., horseshoe kidney)

• Vital Signs: Tachycardia and hypertension due to severe pain; fever indicates infection.
• Inspection: Patient is typically pacing, unable to find a comfortable position.
• Palpation: Costovertebral angle (CVA) tenderness (Lloyd's sign); abdominal guarding is usually absent.

• A. Clinical Assessment: History of sudden-onset unilateral renal colic and CVA tenderness.
• B. Laboratory Testing: Urinalysis, serum chemistries, and metabolic workup.
• C. Imaging Studies: Primary modalities include non-contrast CT and ultrasound.
• D. Functional Tests: 24-hour urine collection to assess metabolic risk factors.
• E. Biopsy Findings: Not clinically indicated unless evaluating underlying nephrocalcinosis.
• F. Genetic Testing: Indicated for suspected cystinuria or primary hyperoxaluria.
• G. Differential Diagnosis: Diverticulitis, appendicitis, pyelonephritis, ruptured abdominal aortic aneurysm (AAA).

Urinalysis

• Type: Urine Test


• Purpose: Evaluate for hematuria, crystalluria, and infection.


• Expected Findings: Microscopic or macroscopic hematuria, elevated pH (struvite) or low pH (uric acid).


• Interpretation: Confirms urinary tract involvement; presence of nitrites or white blood cells suggests co-existing infection.

Non-Contrast Helical CT Abdomen and Pelvis: Purpose: Confirm presence, size, location, and density of the stone.

• Typical Findings: Hyperdense focus within the renal parenchyma, collecting system, or ureter.


• Clinical Importance: Gold standard diagnostic tool with >95% sensitivity and specificity.

• Typical Findings: Echogenic focus with posterior acoustic shadowing and hydronephrosis.


• Clinical Importance: Safe, repeatable, but less sensitive for small ureteral stones.

• Acute Appendicitis: Right lower quadrant pain; lacks hematuria; presents with localized peritoneal signs.
• Ruptured Abdominal Aortic Aneurysm (AAA): Severe back pain, hypotension, and pulsatile abdominal mass in older patients.
• Acute Pyelonephritis: Flank pain accompanied by high fever, pyuria, and leukocytosis; lacks spasmodic colic.

• Urosepsis (medical emergency)
• Persistent hydronephrosis leading to renal atrophy
• Ureteral stricture
• Chronic kidney disease (CKD) from recurrent obstruction

• Most stones <5 mm pass spontaneously.
• Recurrence rate is 50% within 5-10 years without metabolic prevention.

• Hydration targeting urine output >2.0 L/day.
• Limit high-oxalate foods (spinach, nuts, tea) for calcium oxalate stone formers.
