人工肾积水下MPCNL治疗无积水肾盏憩室结石的疗效观察

目的：探讨微创经皮肾镜碎石术（MPCNL）治疗肾盏憩室结石的可行性与有效性。方法：回顾性分析2011年3月～2013年3月应用MPCNI。治疗肾盏憩室结石患者58例的临床资料：采用c臂X线机辅助穿刺建立经皮肾通道，应用气压弹道碎石并取出，同时术中视具体情况采用电凝憩室囊壁或扩张憩室盏颈。结果：手术时间（107±43）min，一次性取尽无残石49例，占84．5％。平均住院7天，出院时症状缓解53例，症状减轻5例。结论：MPCNI。治疗合并临床症状的肾盏憩室结石疗效确切，创伤小，恢复快，可反复操作，可作为临床选择的治疗方式之一。

Application of artificial hydronephrosis with minimally invasive percutaneous nephrolithotripsy in management of calyceal diverticular calculi without hydronephrosis

Objective：To investigate the feasibility and efficacy of MPCNL for the treatment of calyceal diver- ticular calculi. Method：Clinical data of 58 cases from March 2011 to March 2013 who underwent minimally invasive percutaneous nephrolithotripsy （MPCNI.） were summarized and analyzed retrospectively. Under the guide of C- arm X-ray apparatus, we performed pneumatic lithotripsy and the diverticulum was managed by electrically coagu- lating the diverticular wall or dilating the diverticular neck. Result： Mean operative time of all patients was （107±43） mins. Stone-free rate was 84.5% （49/58）. Mean hospital stay was 7 days. The symptoms of fifty-three cases vanished and five cases decreased. Conclusion： According to our study, MPCNL is effective in treating calyceal di- verticular calculi. It could be offered as an alternative therapy for symptomatic ealyceal divertieular calculi because of its high stone-free rate, less invasion and satisfied recovery.
