微创经皮肾取石术治疗幼儿上尿路结石的临床分析

Treatment of minimally invasive percutaneous nephrolithotomy in children with upper urinary tract calculi

目的探讨微创经皮肾取石术(MPCNL)治疗幼儿上尿路结石的安全性及临床疗效。方法2008年9月至2008年10月,采用MPCNL技术治疗幼儿上尿路结石7例,合并轻度积水1例,中度肾积水2例,重度肾积水4例。其中1例双侧结石。结果8侧肾脏均为16F单通道取石,术后仅1侧肾小盏残留小结石,其余结石完全清除。无严重并发症。结论MPCNL治疗幼儿上尿路结石合并肾积水安全、有效,同时具有创伤小、恢复快等优点。

Objective To evaluate the safety and clinical efficacy of minimally invasive percutaneous nephrolithotomy （MPCNL） in treating pediatric upper urinary tract calculi. Methods Seven cases with pediatric upper urinary tract calculi underwent minimally invasive percutaneous nephrolithotomy from September to October 2008. One case combined with mild hydrone Phrosis, moderate hydronephrosis two cases, severe hydronephrosis four cases. Results All cases were acheieved by one-stage MPCNL. 16F single tract was used for all cases. Only one side of the small kidney calculi was remained. No major complications occurred in these cases. Conclusions Minimally invasive percutaneous nephrolithotomy is safe and effective in treating pediatric upper urinary tract stones with less trauma and shorter convalescence.
