微创经皮肾镜碎石取石术治疗输尿管上段结石

Minimally invasive percutaneous nephrolithotomy for the treatment of upper ureteral stone

目的探讨微创经皮肾镜碎石取石术MPCNL治疗输尿管上段结石的疗效及安全性。方法回顾性分析2004年9月至2010年3月83例采用微创经皮肾镜碎石取石术治疗输尿管上段结石的患者资料。男51例,女32例。年龄20~68岁。结石大小1.0cm×0.6cm^2.5cm×1.3cm。其中合并同侧肾轻度积水24例、中度积水43例、重度积水12例、无积水4例。结果 83例均一期取石,结石清除率100%,平均手术时间30~70min,术中无穿刺致周围脏器损伤,无输血病例及严重并发症发生,术后平均住院时间7d。结论微创经皮肾镜碎石取石术治疗输尿管上段结石高效、微创、安全。

Objectives To explore the efficiency and safety of treatment of upper ureteral stone using minimally invasive per-cutaneous nephrolithotomy（MPCNL）.Methods From September 2004 to March 2010,83 patients（aged from 20 to 68 years old）with upper ureteral stone underwent MPCNL in our hospital were enrolled the study.The characteristics regarding operation and compli-cations were recorded and analysed retrospectively.Results All of the procedures were successful.No residual stone after the first procedure were observed.The rate of clear of stone was 100%.The mean operative time is 30~70 min.No renal hemorrhage or kid-ney damage caused by the operation were determined.No transfusion was needed.The mean hospital time was 7 days.Conclusions MPCNL is a mini-invasive operation.It is safety and efficiency in treatment of upper ureteral calculi.
