微创经皮肾输尿管镜术治疗肾结石508例

目的探讨微创经皮肾输尿管镜取石术治疗肾结石的疗效。方法采用经皮肾输尿管镜取石术治疗肾结石患者508例。结果468例行一期穿刺取石，40例行二期取石，补充体外冲击波碎石（ESWL）治疗31例。所有病例均为单通道取石，结石清除率91．7％，手术时间平均为87min，平均住院时间11d。未发生大出血、肾功能损害等严重并发症。结论微创经皮肾镜取石术（MPCNL）治疗肾结石安全高效，具有创伤小、恢复快、结石清除率高等优点，是治疗肾结石的一种好方法。

Minimally invasive percutaneous nephrolithotomy for renal calculi

Objective To explore the clinical effect of Minimally invasive Pereutaneous Nephrolithotomy for renal calculi. Methods To analyze retrospectively clinical data of 508 cases of renal calculi who had administered to treat by percutaneous ureterorenoscope lithotripsy. Results 468 cases were operated in first stage by percutaneous nephrolithotripsy and ureterorenoscope lithotripsy. 40 cases were operated in second stage by percutaneous nephrolithotripsy and ureterorenoscope lithotripsy. And 31 cases accepted ESWL as a supplemental treatment. All cases were underwent minimally invasive percutancous nephrolithotomy and ureterorenoscope lithotripsy by single tract. The average time for surgery was 87 minutes. The average period in hospital was l I days. The stone clearance rate was 91.7% with no severe complications, such as hemorrhage or renal function deterioration. Conclusion It is effective and safe that percutaneous nephrolithotomy and ureterorenoscope lithotripsy with a combination ultrasonic lithotripsy for renal calculi with advantage of minimal invasive, high success ratio, quick recovery and short period in hospital. It is a ideal method in the treatment of residual calculi.
