输尿管镜下钬激光微创治疗输尿管下段狭窄合并结石的临床研究

摘要

Objective To investigate the effect of ureteroscopic holmium laser for the minimally invasive treat‐ment of lower ureteral stenosis complicating stone .Methods The clinical data in 29 patients with lower ureteral ste‐nosis complicating stone treated with holmium laser lithotripsy through ureteroscope in the Chongqing Cavalier Hos‐pital from August 2010 to August 2013 were retrospectively analyzed .Results 25 cases simultaneously accomplished the internal urethrotomy and lithotripsy by hard ureteroscope combined with holmium laser without the severe com‐plications of massive hemorrhage ,urinary fistula .The once clearance rate of stone was 92 .0% (23/25) .The improve‐ment rate of hydronephrosis was 78 .3% (18/23) .Conclusion Ureteroscopic holmium laser for simultaneously mini‐mally invasive treatment of lower ureteral stenosis complicating stone is safe and effective ,and has certain clinical value .%目的：探讨输尿管镜下钬激光微创治疗输尿管下段狭窄合并结石的临床疗效。方法选取2010年8月至2013年8月重庆骑士医院收治的输尿管下段狭窄合并结石的患者29例，行输尿管镜下钬激光内切开术并碎石术的临床资料。结果25例同期完成输尿管硬镜联合钬激光内切开术并碎石术，无大出血、严重感染、尿漏等严重并发症。结石一次性清除率为92．0％（23／25），肾积水改善率为78．3％（18／23）。结论输尿管镜下钬激光同期微创治疗输尿管下段狭窄合并结石是安全有效的，具有一定的临床价值。
