经后中组肾盏径路行微创经皮肾取石治疗复杂性肾结石

目的：评价经后中组肾盏径路行微创经皮肾取石(MPCNL)术处理复杂性肾结石的疗效。方法：从2002年6月-2004年7月采用经后中组肾盏径路行MPCNL处理复杂性肾结石患者152例。结果：术后结石清除率为86．18％(131／152例，包括一期多次取石)。一期结石完全清除率达65．28％。仅15例(9．87％)接受辅助的ESWL治疗，6例(3．95％)需要重建另一通道再行MPCNL治疗。结论：经后中组肾盏径路行MPCNL治疗复杂性肾结石安全高效，有很高的结石清除率；残留结石可联合ESWL来提高疗效。

Minimally invasive percutaneous nephrolithotomy in the management of complex urinary calculi: a middle calyx puncture approach

Objective:To evaluate the safety and efficacy of Mini-percutaneous nephrolithotomy procedure (MPCNL) in management of complex upper ureteric calcul through middle calyx puncture approach.Methods:A retrospective analysis was done of 152 consecutive patients with complex renal calculi accepted MPCNL between Jun 2002 to Jul 2004 at our center.Results:MPCNL was performed on 152 complete renal calculi. After MPCNL, the stone-free rate was 86.18 %(131/152) in 3 days post-operation. Only 15 required auxiliary Extracorporeal Shock Wave Lithotripsy, and 6 cases needed re-MPCNL through another access.Conclusions:The use of MPCNL for complex renal calculi is safe and effective, high stone-free rate can be obtained with MPCNL. For the presence of residual stones, the effect can be raised with the auxiliary ESWL.
