微创经皮肾镜取石术治疗开放性手术后复发肾结石的效果观察

目的观察微创经皮肾镜取石术治疗开放手术后的复发肾结石的疗效。方法回顾性分析2006年5月到2010年5月45例开放手术后的复发肾结石患者的临床资料,并与同期开展的86例初治肾结石患者的微创经皮肾取石术作对照研究。结果 45例观察组患者单通道取石17例,双通道取石25例,三通道取石3例;结石总取净率86.7%;平均手术时间121±41min;平均住院时间8.2d。对照组采用单通道取石54例,二通道取石28例,三通道手术4例;手术时间113±47min,平均住院时间7.5d;结石清除率90.7%。两组患者手术时间、住院时间及结石总取净率均无显著性差异(P>0.05),对照组采用单通道取石比例高于观察组(P<0.05)。结论微创经皮肾镜取石术是治疗复发性肾结石的有效方法。

Treatment of recurrent stone after open nephrolithotomy with mini -percutaneous nephrolithotomy

Objective To investigate the efficacy of mini-percutaneous nephrolithotomy for the treatment of recurrent stone after open nephrolithotomy.Methods From May 2006 to May 2010,the clinical data were retrospectively analyzed in 45 cases with recurrent stone after open nephrolithotomy and 86 naive patients with renal calculus as control.Results The patients with recurrent stone were treated with one-channel operations in 17 cases,two-channel in 25 cases and three-channel in 3 cases.The stone-free rate reached 86.7%.The average operative duration was 121±41 min and the average duration of hospitalization was 8.2 days.The patients of control group were treated with one-channel operations in 54 cases,two-channel in 28 cases and three-channel in 4 cases.The stone-free rate was 90.7%.The average operative duration was 113±47 min and the average duration of hospitalization was 7.5 days.There was no significant difference between the two groups in operative duration,duration of hospitalization and the stone-free rate(P>0.05).The patients with recurrent stone treated with one-channel were more than that in control group(P<0.05).Conclusions Mini-percutaneous nephrolithotomy is an effective method in the treatment of recurrent renal calculus.
