微创经皮肾镜术治疗复杂性肾结石

目的探讨微创经皮肾镜取石术（MPCNL）治疗复杂性肾结石的微创性、安全性、有效性。方法本组106例复杂性肾结石121次手术均采用微创经皮肾镜取石术治疗。结果121次手术中单通道取石89例，双通道29例，三通道3例，一期取石90例，二期取石11例，5例残留结石，配合体外冲击波碎石术（ESWL）。结石取净率为92．6％，平均手术时间为91min，出血100—900ml，5例输血200～400ml，无严重并发症发生。结论微创经皮肾镜取石术治疗复杂性肾结石微创、安全、高效，具有临床推广应用价值。

Minimally invasive percutaneous nephrolithotomy for the treatment of complicated renal calculi

Objective To explore the safety, feasibility and superiority of minimally invasive percutaneous nephrolithotomy(MPCNL) in treating complicated renal calculi. Methods 106 patients suffering from complicated renal calculi were treated with 121 MPCNL. Results 89 cases underwent MPCNL with single tract ,29 cases with two tracts and 3 cases with three tracts in 106 patients. Renal calculi were cleared completely in 90 patients with one-staged MPCNL, 11 patients with two-staged MPCNL but 5 patients had residual renal calculi and treated with extracorporal shock wave lithotripsy(ESWL) afterwards. 92. 6% calculi free-rate was achieved. Average operation time was 91 minutes,bleeding ranged from 100 to 900 ml and 5 patients accepted 200～400 ml blood. There were no severe complications in all patients. Conclusion MPCNL is a minmally invasive, safe and effective operation for comlicated renal calculi.
