输尿管镜钬激光碎石术治疗输尿管结石536例报告

目的探讨输尿管镜钬激光碎石术治疗输尿管结石的效果。方法回顾性分析536例输尿管结石，直径为0．5～2．0cm，均行输尿管硬镜钬激光碎石术治疗。结石合并息肉形成153例，采用钬激光汽化切割息肉。术后放置双J管2～6周。结果491例一次性碎石成功，成功率为91．6％（491／536），手术时间为15-75min，平均32min。术后1周结石排净率为72．5％（356／491），术后住院时间为1～4d，平均2．5d。结论输尿管镜钬激光碎石术是治疗输尿管结石安全有效的方法。

A clinic alanalysis of ureteroscopic holmium laser lithotripsy for ureteral stones:report of 536 cases

Objective To evaluate the efficacy and safety of ureteroscopic holmium laser lithotripsy for ureteral stones. Methods The clinical data of 536 cases of ureteral calculi treated via ureteroscope with holmium laser lithotripsy were analyzed retrospectively. The size of the stones were 0.5-2.0 cm in diameter. Of them 113 cases had ureteral polyp and they were underwent holmium laser vaporization resection of the polyp. Double J tube was placed after operation for 2-6 weesks. Results The overall stone fragmentation rate was 91.6% （491/536） with a single procedure. The operating time was 15-75 min with a mean of 32min. The stone free rate in one-week postoperation was 72.5% （356/491）. Postoperative hospitalstay was 1 d-4 d with a mean of 2.5 d. Conclusions Holmium laser lithotripsy via ureteroscope is an effective and safe treatment option for ureteral calculi.
