微创经皮肾镜取石术治疗鹿角状结石

目的评价微创经皮肾镜取石术(mini-prec／MPCNL)治疗鹿角状结石患者的疗效及并发症情况。方法回顾性分析2002年4月至2004年10月应用MPCNL治疗32例鹿角状结石患者的临床资料。结果单通道取石28例，二通道3例，三通道1例；一期取石18例，二期14例。无结石率为90．6％。平均手术时间2．3h。一期取净者住院时间为4～6d，平均4．6d。仅1例于术后第6天肾严重出血，经超选择性肾动脉栓塞后治愈。结论MPCNL治疗鹿角状结石的疗效确切，患者痛苦小、恢复快。

Mini-percutaneous nephrolithotomy in treatment of renal staghorn calculus

Objective To evaluate the feasibility and complication of mini-percutaneous nephrolithotomy in the treatment of renal staghorn calculus.Methods From April 2002-Oct 2004, the clinical data were retrospectively analysed in 32 cases of renal staghorn calculus. Results They were treated with one-stage operations in 18 cases, two-stage in 14 cases,of which single channel was used in 28 cases,two- channel in 3 and three- channel in 1. The stone-free rate reached 90.6%. The average operative duration was 2.3 h.The duration of hospitalization was 4-6 days with an average of 4.6 days in one-stage stone-free clearance patients.Only one patient was complicated with severe bleeding on the sixth day after the procedure, and was successfully treated with super-selective arterial embolization. Conclusion MPCNL has definite efficacy in the treatment of renal staghorn calculus with less suffering and shorter recovery time.
