目的探讨微创经皮肾取石术(MPCNL)治疗输尿管上段结石的疗效和安全性。方法我院于2004年4月～2009年5月期间,采用微创经皮肾取石治疗输尿管上段结石121例。结果所有病例均一次穿刺取石,取石时间为30～100min(平均70min),肾造瘘管留置时间为4～7d(平均5d),双J管于术后1～4周拨除,术后第3d复查X线摄片,无石率为97.5%,术后住院时间6～10d(平均7.8d)。结论微创经皮肾取石术治疗输尿管上段结石,具有创伤小、手术成功率高、结石清除率高、并发症少等优点,是治疗输尿管上段结石的理想方法。值得在有条件的基层医院推荐开展。
Objective To investigate the efficacy and safety of minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of upper ureteral calculi. Methods From April 2004 to May 2009, our hospital treated 121 cases of upper ureteral calculi with minimally invasive percutaneous nephrolithotomy. Results All cases were punctured by a single puncture. The time of stone retrieval was 30-100min (average 70min), the length of renal fistula was 4 ~ 7d (average 5d), double J tube was removed 1 ~ 4 weeks after operation, 3d Review X-ray, stone-free rate was 97.5%, postoperative hospital stay 6 ~ 10d (average 7.8d). Conclusion Minimally invasive percutaneous nephrolithotomy for the treatment of upper ureteral calculi has the advantages of small trauma, high operation success rate, high stone clearance rate and few complications. It is an ideal method for the treatment of upper ureteral calculi. Worthy of recommendation in the grassroots hospitals with conditions.
