经皮肾微造瘘输尿管镜取石术治疗肾结石12例报告

Treatment of renal calculus with minimally invasive percutaneous nephrolithotomy in 12 patients

目的探讨经皮肾微造瘘输尿管镜取石术治疗肾结石的疗效。方法选择2004年8月至2005年3月经皮肾微造瘘输尿管镜取石治疗肾结石者12例,男7例,女5例;年龄32～69岁,平均45岁。结石长径为0.7～2.5cm,单发性结石4例,多发性结石8例。其中鹿角状结石3例,双肾结石2例,孤立肾并肾结石1例,有开放手术史2例。结果12例均行一期穿刺取石,1次取石11例,2次取石1例;单通道取石10例,双通道取石2例。结石清除率为83%;平均手术时间135min;术中明显出血1例;平均住院12d。结论经皮肾微造瘘输尿管镜取石术具有创伤小、恢复时间短、并发症少等优点,是治疗肾结石的一种有效方式。

Objective To evaluate the efficiency of minimal invasive pereutaneous nephrolithotomy in treating renal calculus. Methods 12 patients with renal calculus were treated with minimal invasive pereutaneous nephrolithotomy in our hospital from August 2004 to March 2005. Of the 12 cases, 7 were male, 5 were female and their age ranged from 32 to 69. The diameter of the stone of these patients ranged from 0.7cm to 2.5cm. Sole calculus were found in 4 cases, multiple calculi in 8 cases respectively. Simutaneously, staghorn calculi in 3, bilateral renal calculi in 2, solitary kidney calculi in 1, and 2 cases had ever received open nephrolithotomy. Results All cases were underwent stage one procedure, one session procedure in 11, two sessions in 1. Single tract procedure in 10, multiple tract in 2. The stone-free rate was 83%. Average operative time was 135 minutes. The mean hospitalization time was 12 days. Conclusions Minimal invasive pereutaneous nephrolithotomy is an effective technique in treating renal calculi owing to less morbidity and quickly return to preoperative activity and less complication.
