探讨选择不同能量和频率钬激光碎石术治疗输尿管结石的技巧与方法。方法:应用硬性输尿管镜和钬激光在不同频率和脉冲能量下(先由低能量高频率开始)针对96例输尿管结石患者碎石治疗。结石横径3~16mm,纵径9~33mm。单发结石58例,上段16例,中段27例,下段15例。多发结石(一侧多发或双侧输尿管结石)38例。结果:91例手术成功(94.8%)。手术时间25~113min,平均为42min。87例2~6周内结石全部排净(95.6%)。结论:输尿管镜下适当的钬激光碎石术技巧和方法治疗输尿管结石安全有效,成功率高。
To explore the selection of different energy and frequency holmium laser lithotripsy of ureteral calculi tips and methods. METHODS: A total of 96 patients with ureteral calculi underwent gravel therapy with rigid ureteroscope and holmium laser at different frequencies and pulse energies, starting with low energy and high frequency. Stone diameter 3 ~ 16mm, longitudinal diameter 9 ~ 33mm. 58 cases of single stone, the upper 16 cases, the middle 27 cases, the lower 15 cases. Multiple stones (multiple or bilateral ureteral calculi) in 38 cases. Results: 91 cases were successful (94.8%). Surgery time 25 ~ 113min, an average of 42min. 87 cases of 2 to 6 weeks all the stones row net (95.6%). Conclusion: The appropriate ureteroscopic holmium laser lithotripsy techniques and methods for the treatment of ureteral stones safe and effective, high success rate.
