输尿管镜下钬激光碎石治疗输尿管结石160例临床分析

目的：分析输尿管镜下钬激光碎石治疗输尿管结石的临床疗效及安全性。方法回顾性分析160例输尿管结石患者的临床资料，所有患者在硬膜外或全身麻醉下手术，通过导丝引导插入输尿管镜，行钬激光碎石，在术后留置双J管2～4周。结果160例患者中，单次手术结石粉碎率为94．37％；平均手术时间为51 min；所有患者均有轻度血尿，3～4 d可消失；通过1～3个月随访，结石排净率为97．5％；手术输尿管上段结石一次碎石成功率为70．27％，中、下段结石一次性碎石成功率为99．20％。结论通过输尿管镜下钬激光碎石术治疗输尿管结石安全、高效，并且是一种微创、并发症少的碎石方法。

Analysis of holmium laser lithotripsy under ureteroscopy in the treatment of 160 patients with ureteral calculi

Objective To analyze the clinical efficacy and safety of holmium laser lithotripsy under ureteros-copy in the treatment of ureteral calculi .Methods The clinical data of 160 patients with ureteral calculi were retro-spectively analyzed .All patients received the epidural or general anesthesia surgery ,guide wire was inserted through ureteroscopy,holmium laser lithotripsy line,postoperative indwelling double J tube 2-4 weeks.Results Of 160 cases, a single stone crushing operation was 94.37%;mean operative time was 51min.All patients had mild hematuria,3 ~4d may disappear.By 1 to 3 months follow-up,stone clearance rate was 97.5%.The success rate of gravel for surgical ureteral calculi was 70.27%, and middle and lower ureteral stone gravel-time success rate was 99.20%.Conclusion Holmium laser lithotripsy under ureteroscope in the treatment of ureteral calculi is safe ,effective,and has minimally invasive,fewer complications.
