微通道经皮肾镜取石术联合钬激光碎石治疗多发肾盏结石临床分析

目的探讨微通道经皮肾镜取石术联合钬激光碎石治疗多发肾盏结石的临床效果及安全性。方法回顾性分析2010年5月至2013年12月手术治疗的164例多发肾盏结石患者的临床资料，按手术方式分为微通道组与标准通道组．比较两组患者手术时间、结石清除率、并发症发生率和住院时间。结果两组患者手术时间比较，差异无统计学意义（P〉0．05）。微通道组结石清除率高于标准通道组，标准通道组术后并发症发生率高于微通道组，微通道组住院时间短于标准通道组，差异均有统计学意义（P〈0．05）。结论微通道经皮肾镜取石术联合钬激光碎石治疗多发肾盏结石疗效可靠，术后并发症少，适宜于临床开展。

Clinical analysis of minimally channel percutaneous nephrolithotomy combined with laser holmium lithotripsy for multi-pie calyceal calculi

Objective To investigate the clinical effect and safety of minimally channel percutaneous nephrolithotomy （MPNL） combined with holmium laser lithotrlpsy in treating multiple ealyeeal calculus. Methods Retrospective analysis was conducted on the clinical data of 164 patients with multiple calyceal calculus ,who received operation from May 2010 to December 2013. The patients were divided into the minimal channel （MC） group and the standard channel （SC） group according to surgical op- tions to compare the operative time, clearance rate of calculus, occurrence rate of complications and hospital stays. Results The difference between the two groups on operative time was not statistically significant（P〉0.05 ） ;the clearance rate of calculus in the MC group was higher than that in SC group with statistically significant difference （P〉0.05） ; the occurrence rate of preoperative complications in the SC group was higher than that in the MC group with statistically significant difference （P〈0.05） ;the hospital stays in the MC group was shorter than that in the SC group, and the difference had statistical significance （P〈0.05）. Conclusions Curative effect of MPNL combined holmium laser lithotripsy in the treatment of multiple calyceal calculus is reliable with less postoperative complications, so MPNL combined holmium laser lithotripsy is worthy of clinical promotion.
