[Using of percutaneous nephrolithotomy in pediatric urolithiasis]

Abstract

Objective: To assess the safety and efficacy of percutaneous nephrolithotomy (PCNL) using ureteroscope and pneumatic intracorporeal lithotripsy in the pediatric age group.

Methods: Twenty-two renal units in 15 patients underwent PCNL at our institute. The patients were all under 14 years old. The average age was 9 years (range 5-14 years). There were 7 bilateral, 8 multiple, and 5 staghorn calculi. The average calculus size was 2.0 (0.9-4.5) cm. The PCNL was done with an X ray-guided peripheral puncture, a planned staged approach in some cases, and minimal tract dilatation with the use of an ureteroscope and pneumatic intracorporeal lithotripsy.

Results: Complete stone clearance was achieved in 20 renal units, giving an overall clearance rate of 91%. Minor pyrexia (< 39 degrees C, < 2 days) was seen in 14 patients, whereas serious pyrexia was seen in 1. The average fall in hemoglobin was 10 g/L, but none of the patients required blood transfusion.

Conclusions: It is safe and effective to cure pediatric urolithiasis with percutaneous nephrolithotomy using ureteroscope and pneumatic intracorporeal and pneumatic intracorporeal lithotripsy.
