微创经皮肾镜取石术治疗上尿路结石1100例疗效观察

【目的】观察微创经皮肾镜取石术（MPCNL）治疗上尿系结石的临床疗效。【方法】对2005年1月至2009年12月1100例上尿路结石患者采用单通道MPCNL。【结果】术后d。结石清除率为99．00％，手术时间平均为（65．5±5．8）min，术后住院时间平均（5．5±1．3）d，术中出血量平均为（75．5±17．3）mL。均无穿刺失败及其他脏器损伤和不良事件，术后有7例患者出现高热（0．64％）。【结论】MPCNL治疗上尿路结石具有结石清除率高，并发症少，手术时间短，术中出血量少，术后住院时间短等优点。

Clinical Observation of the Effect of Minimally Invasive Percutaneous Nephrolithotomy for the Treatment of 1100 Cases of Upper Urinary Stones

Objective] To ohserve the clinical effect of minimally invasive percutaneous nephrolithotomy in the treatment of upper urinary stone. Methods] From January 2005 to December 2009, 1100 cases of upper urinary stone were treated with single percutaneous nephrolithotomy（CMPCNL）. Results] At 3 days after operation, the stone clearance rate was 99.00%.The mean operative time was （65.5±5.8） minutes and the mean postoperative hospital stay was （5.5±1.3） days. The average blood loss was （75.5±17.3） ml. There were no puncture failure, other organ damages and adverse events. Seven patients had postoperative fever （0.64%）. Conclusion] Minimally invasive percutaneous nephrolithotomy for the treatment of upper urinary stone has advantages such as higher clearance rate, fewer complications, shorter operative time, less blood loss and shorter postoperative hospital stay.
