微创经皮肾镜气压弹道碎石术与开放手术治疗复杂肾结石的疗效比较

Comparision of complicated renal stone treatment between tradional operation and MPCNL

目的比较微创经皮肾镜气压弹道碎石术（MPCNL）与开放手术治疗肾结石的疗效。方法分析MPCNL和肾切开取石的治疗效果，比较两种术式在手术时间、术中出血量、结石清除率、术后住院时间等方面的差异。结果开放手术组及MPCNL组平均手术时间、平均出血量、术后住院时间分别为（147±31）min和（299±121）min、（257±135）ml和（163±90）ml、（12．5±2．8）d和（8．2±2．6）d，差异均有统计学意义（P〈0．05）。结论MPCNL相比开放手术治疗肾结石更安全、快速、有效，是治疗肾结石的理想方法。

Objective To investigate the therapeutic effect of the minimally invisive percutaneous nephrolithotomy（MPCNL） in the treatment of kidney nephrolithiasis comparing with open surgery. Methods To analyze and compare the therapeutic effect between the operation and MPCNU The differenees in operating time, average bleeding volume during operation, stone clearance, postoperative hospital stay of the two procedures were compared. Results The mean operation time, average bleeding volume during operation, postoperative hospital stay of the PCNL and surgery group were （ 147 ± 31 ） rain vs （299 ± 121 ） rain, （257 ± 135 ） ml vs （163± 90）ml, and（ 12.5± 2.8 ）d vs （8.2 ± 2.6）d, respectively. The differences between the two groups were significant （P 〈 0.05）. Conclusions MPCNL is an excellent form of treatment for kidney nephrolithiasis. It is more reliable, highly effective, rapid and safe procedure than open surgery.
