输尿管镜下钬激光碎石术治疗输尿管结石66例疗效分析

目的：观察研究输尿管镜下钬激光碎石术治疗输尿管结石的临床疗效。方法：选取本院收治的66例输尿管结石患者作为研究对象，其中输尿管上段结石26例，中、下段40例。结石大小0.6~1.9 cm，结石周围合并息肉14例。均经过尿道、膀胱置入输尿管镜，到达结石处后，将连接钬激光机的光纤进行碎石治疗，设定碎石功率15~30 W，频率10~20 Hz。观察研究输尿管镜下钬激光碎石术的有效性和安全性。结果：66例患者中有63例一次性碎石成功，总成功率为95.45%，结石排净率为98.48%（65/66），其中2例患者改行经皮肾镜碎石术，1例患者改留置双J管后行体外冲击波碎石术。结论：输尿管镜下钬激光碎石术治疗输尿管结石具有微创、安全、效果好、恢复快等优点，可作为首选治疗方法，值得临床广泛推广使用。

The Efficacy Of 66 Cases Of Ureteroscopic Holmium Laser Lithotripsy For Ureteral Calculi

Objective：To observe the clinical efficacy of ureteroscope holmium laser lithotripsy for ureteral calculi. Method：66 cases in our hospital with ureteral stones were selected as research subjects,included 26 cases of upper ureteral stones,40 cases of middle and lower sections. The stone size was about 0.6-1.9cm. There were 14 cases of stones surrounding polyps. Both of 66 cases were used ureteroscopy through the urethra,bladder arrived stones department. The ureteroscopy was connected with holmium laser fiber for lithotripsy. Rubble power was set 15-30 W. Frequency was set 10-20 Hz. The effectiveness and safety of ureteroscopic holmium laser lithotripsy was observed. Result：63 cases were disposable gravel success,with a total success rate of 95.45%,stone free rate of 98.48%. Conclusion：Ureteroscope holmium laser lithotripsy for ureteral calculi with advantage of minimally invasive,safe,effective,quick recovery,etc. It can be used as the preferred treatment method.It’s worthy of clinical widely used.
