微创经皮肾穿刺输尿管镜钬激光碎石术治疗肾结石

Treatment of renal calculi on minimally invasive percutaneous nephrolithotomy with ureteroscopic holmimium ： YAG laser lithotripsy

目的探讨微创经皮肾穿刺输尿管镜钬激光碎石术治疗肾结石的安全性、效果及优点。方法回顾性分析20例肾结石患者，在B超或C臂X线监视下建立经皮肾通道，并行输尿管镜钬激光治疗。结果结石一次取净率90％，无术后大出血及尿瘘。结论mini—PCNL术治疗肾结石具有创伤小、操作安全可靠，结石一次取净率高、术后恢复快等优点。

Objectives To assess the safety ,feasibility and superiority of minimally invasive percutaneous nephrolithotomy （ mini - PCNL） with ureteroscopic holmimium. Methods The data of 20 patients with renal calculi who had undergone mimi - PCNL from August 2004 to April 2008 were retrospectively analyzed. Build up the tract of mini - PCNL under the guide of B - ultrasound or C x - ray machine ,All of renal calculi were treated by mini - PCNL with ureteroscopic holmimium ： YAG laser lithotripsy. Results The total stone - free rate was 90%. And no complications such as severe bleeding and urinary fistula happened. Conclusions Treatment of the renal stone with mini - PCNL was a safe , effective rapid recovery and less invasive method.
