The extracorporeal shock-wave lithotripsy (ESWL) is still the treatment of choice for almost all stones in children. But with advances in instrumentation, endourological procedures are being performed more frequently in younger patients. Especially in the treatment of distal ureteral stones retrograde ureteroscopy now competes with ESWL. Finally, the recent literature supports percutaneous nephrolithotomy as a safe and effective treatment option for large renal calculi and staghorn calculi. This gives the clinician the opportunity to choose from a wide range of treatment alternatives. Proper treatment planning, technique and availability of appropriate instrumentation are important to achieve an optimal outcome.
