Percutaneous removal of renal and ureteral calculi has become an established and successful procedure in adults. Stone disease in children often is metabolic or infectious in origin and multiple surgical procedures during a long interval may be required. Therefore, percutaneous stone removal could be particularly advantageous in these patients. We have performed percutaneous stone removal successfully in 7 children, none of whom required a second procedure or were discharged from the hospital with a nephrostomy tube.
