经皮肾微造瘘输尿管镜取石术治疗肾盏憩室结石

Minimally invasive percutaneous nephrolithotomy for calyceal diverticular calculi

目的评估经皮肾微造瘘输尿管镜取石术(Minimally invasive percutaneous nephrolithotomy,MPC-NL)治疗肾盏憩室结石的临床价值。方法回顾分析该院2001年2月～2005年10月应用经皮肾微造瘘输尿管镜取石术治疗的13例肾盏憩室结石患者的临床资料。结果12例均一次碎石取石成功,1例合并肾盂结石经配合体外冲击波碎石后结石排出。11例患者均随访(13±3)个月,未发现肾盏憩室内结石再发,2例随访1个月后失访。结论MPCNL是一种值得临床广泛推广的治疗肾盏憩室结石的微创方法之一。

[Objective] To evaluate minimally invasive pereutaneous nephrolithotomy（MPCNL） in the treatment of calyceal diverticular calculi. [Methods] The records of 13 cases treated with MPCNL during February 2001 and October 2005 were reviewed and analyzed. [Results] 12 cases were treated successfully in a single procedure. But 1 of the cases complicating renal pelvis calculi was treated by extracorporeal shock wave lithotripsy after operation, eventually stones were discharged. 11 cases had followup for （13±3） months in whom there were no stone found in all calyceal diverticula. 2 patients had followup for one month and were lost. [Conclusion] MPCNL approach is the most effective and micro-invasive treatment for calyceal diverticular calculi and to be worth generalizing in clinic.
