探讨输尿管镜钬激光碎石治疗嵌顿输尿管结石的有效性和安全性

目的 探讨输尿管镜钬激光碎石治疗嵌顿输尿管结石的有效性和安全性.方法 分析2007年8月～2011年12月间某院输尿管镜下钬激光碎石治疗嵌顿输尿管结石85例患者临床资料,对碎石率、排石率和并发症等进行统计分析.结果 共行103侧输尿管镜钬激光碎石,碎石成功率为90.3％ (93/103),输尿管上段与中、下段结石碎石成功率分别为73.9％ (17/23)、95.0％ (76/80).随访3～18个月,结石排净率85.4％ (88/103).3例发现输尿管狭窄,并发症发生率2.9％ (3/103).结论 输尿管镜钬激光碎石治疗嵌顿输尿管结石安全、有效,尤其适用于中、下段输尿管结石.

Discussion of effectiveness and safety of the holmium laser lithotripsy treatment for embedded ureteral calculi

OBJECTIVE To discuss the effectiveness and safety of the holmium laser lithotripsy treatment for embedded ureteral calculi.METHODS Analysed the grind rate,removing rate and complication of 85 embedded ureteral calculi cases treated by holmium laser lithotripsy in our hospital from 2007.8-2011.12.RESULTS A total 103 side holmium laser lithotripsies were carried out,and the successful rate of lithotripsy was 90.3%(93/103);Successful rate of lithotripsy for upper,middle and low segment of ureteral were 73.9%(17/23),95.0%(76/80)respectively.All the patients were followed-up for 3-18 months,and the total stone-free rate was 85.4%(88/103).Ureterostenosis was found in 3 cases,and the complication occurrence rate was 2.9%(3/103).CONCLUSION Holmium laser lithotripsy treatment for embedded ureteral calculi is safe and effective,especially for middle and low segment of ureteral calculi.
