Common Causes of Stone Formation
Congenital anomalies of the kidneys and urinary tract causing urinary stasis;
Metabolic disorders (excess calcium, oxalate, or uric acid in the urine);
Urinary tract infections (UTIs);
Inadequate fluid intake and hot climates.
When to See a Pediatric Urologist Immediately
Sudden, severe pain in the lower back, flank, or lower abdomen;
Irritability, crying during urination, or pulling legs up to the abdomen in infants;
Visible changes in urine color (pink, brownish, or cloudy sediment);
Frequent, painful urination urges, nausea, vomiting, or unexplained fever.
Diagnostic Approach
Renal and Bladder Ultrasound (US): The safe, first-line imaging method;
Urinalysis and Urine Biochemistry: To evaluate crystals, infection, and mineral levels;
Low-Dose CT Scan: Used when precise stone size, density, and localization are needed prior to intervention.
Modern Treatment Options
Small Stones (\le 3–4 mm): Often pass spontaneously with increased hydration and medical expulsive therapy.
Larger Stones: Managed without open surgery via minimally invasive procedures, including Shock Wave Lithotripsy (SWL), flexible ureteroscopy, or mini-percutaneous nephrolithotomy (mini-PCNL) using laser fragmentation.
Key Prevention Measures include maintaining optimal daily water intake, reducing salt and ultra-processed foods, and scheduling regular follow-up ultrasound scans.
