微创经皮肾镜碎石取石术治疗鹿角形肾结石52例分析

目的:探讨微创经皮肾镜碎石取石术(mPCNL)治疗鹿角形肾结石的疗效和安全性。方法:应用PCNL治疗52例鹿角形肾结石,采用实时彩色多普勒超声引导穿刺、扩张建立F16微通道,钬激光粉碎结石。统计结石清除率以及手术并发症等。结果:52例均一期建立通道。一次治疗结石清除率71.2%,总清除率84.7%,术后2例出现发热,未发生脏器损伤和感染性休克病例。结论:mPCNL治疗鹿角形肾结石效率高、出血量少,是治疗鹿角形肾结石的安全、有效方法。

Minimally invasive percutaneous nephrolithotripsy in patients with staghorn calculi:an analysis of 52 cases

Objective:To investigate the efficacy and safety of ultrsonography-guided minimally invasive percutaneous nephrolithotomy(mPCNL) in management of renal staghorn calculi. Methods:52 patients with renal staghorn calculi had undergone mPCNL with holmium YAGlaser lithotripsy accessed by one steps dilation to F16 tract with ultrasound guidance.Stone-free rate and complication were assessed. Results:The stone-free rate was 71.2% after the first session,84.7% at the end of session.2 cases had high fever after surgery,no other adverse event was noted. Conclusions:Invasive percutaneous nephrolithotomy in management of renal staghorn calculi can crash calculi quickly and reduce the time of operation,efficient technique and less trauma.It is an effective and safe technique for renal staghorn calculi.
