Abstract: Objective To review the experience with mini-percutaneous nephrolithotomy (MPC NL) in early children and discuss its safety and indications. Methods Between Dec 2005 and Apr 2009, 34 boys and 22 girls aged 7 months to 36 months underwent MPCNL for upper urinary tract calculi. Clinical data were analyzed retrospectively. Results The mini-percutaneous renal access of 12 - 16 F was successfully established in 56 patients under realtime colour ultrasound guidance and immediate lithotripsy was performed. Average accessing time was 2. 9±0. 6 min, and stone management time was 13. 9±3. 2 min. No severe complication occurred. Stone free rate was 92. 5%. Conclusions MPCNL was highly effective to treat stone disease in this population. The indications for MPCNL in early children include large upper tract stone burden ( greater than 1. 5 cm ) , multiple renal calculi, staghorn calculi, stones with high-grade obstruction, and those could not be cleared by EWSL or other treatment conservatively.
