经皮肾镜与开放手术在复杂性肾结石治疗效果的对比研究

目的：探讨B超引导下经皮肾镜在复杂性肾结石治疗的安全性和有效性。方法：对复杂性肾结石经皮肾镜手术的31例（微创组）与开放手术52例患者（开放组），进行了手术安全性和有效性的比较。结果：两组比较，微创组在手术时间、肾造瘘留管时间及术后下床活动开始时间明显短于开放组，而且平均输血量和术后并发症也明显少于开放组（P〈0．05）；在结石清除率及复发率上两组间比较，差异无统计学意义（P〉0．05）。结论：经皮肾镜气压弹道碎石联合超声碎石法，简便、安全、有效、价廉，值得临床推广应用。

Therapeutic efficacy comparison between percutaneous nephrolithotomy and open surgery for nephrolithiasis

Objective To investigate the safety and effects of percutaneous nephrolithotomy under B ultrasound guidance for complex nephrolithiasis.MethodThe safety and effects of 31 nephrolithiasis patients treated by percutaneous nephrolithotomy (the minimally group) were compared with 52 nephrolithiasis patients subjected to open surgery (the open group) in our hospital from Jan 2000 to Apr 2008.ResultsThe minimally invasive group were all significantly less than the open group in operation time,detaining time of draining tube of stoma,the time needed for starting ambulation,the average amount of blood transfusion and complications after operation(P<0.05).But there were no marked discrepancy in the stone clearance and recrudescence.ConclusionPercutaneous nephrolithotomy supersonic barometric pressure trajectory crushed stone treatment is a handy,safety,effective and low-cost technique.It is worth generalizing in minority-region.
