超声引导多通道经皮肾镜取石术治疗复杂性肾结石

目的 评估超声引导多通道微创经皮肾镜取石术(PCNL)治疗复杂性肾结石的方法及效果.方法 对46 例接受超声引导微创多通道PCNL 的患者进行回顾性分析.其中鹿角型肾结石8 例,多发性肾结石38 例.部分残留结石行二期或三期手术取石.结果 双通道取石40 例,三通道6 例;一期取净率76.1%,总结石取尽率为95.6%;一期手术平均手术时间1.8 h.手术平均出血量240 ml.结论 超声引导多通道PCNL 治疗复杂性肾结石安全、有效.

Ultrasound guided multiple-channel percutaneous nephrolithotomy for complex renal calculi

Objective To evaluate the method and effect of ultrasound guided multiple-channel minimally invasive percutaneous nephrolithotripsy for complex renal calculi.Methods The clinical data of 46 patients who underwent ultrasound guided multiple-channel minimally invasive percutaneous nephrolithotomy were reviewed,including 38 cases with multiple renal stones and 8 cases with staghorn calculi.Results Forty cases were established two channels,and 6 cases were established three channels.The stone clearance rate in stage I was 76.1%,and the total clearance rate was 95.6%.The average operation time in stage I was 1.8 h,and the average volume of blood loss was 240 ml.Conclusions Ultrasound guided minimally invasive percutaneous nephrolithotripsy via poly-channels is a safe and effective way to treat complex renal calculi.
