钬激光治疗泌尿系结石

Ureteroscopic holmium:YAG laser lithotripsy for managing urinary tract calculi

目的 探讨输尿管镜钬激光治疗输尿管结石的有效性和安全性。方法 采用输尿管镜钬激光技术治疗 16 8例输尿管结石 ,其中输尿管上段结石 2 7例 ,中段结石 33例 ,下段结石 10 8例 ;经尿道膀胱镜钬激光技术治疗膀胱结石 12例。术后 4～ 6周复查计算各自结石排净率 (排净例数 /例数 )。结果 输尿管上、中、下段结石的排净率分别为 93% (2 5 / 2 7)、94 % (31/ 33)、94 % (10 2 / 10 8) ,并发症为 5 % (8/ 16 8) ;而膀胱结石的排净率为 10 0 % ,无并发症。结论 输尿管镜钬激光是治疗输尿管结石的有效、安全方法。

Objective To evaluate the effectiveness and safty of ureteroscopic holmium:YAG laser lithotripsy for managing ureteral calculi. Methods Ureteroscopic holmium:YAG laser lithotripsy was used in 168 ureteral calculi (proximal 27 cases,middle 33 cases,distal 108 cases).Transurethral cystoscopic holmium:YAG laser lithotripsy in 12 bladder calculi. Results Four to six weeks after operation,The stone-free rate was 93%(25/27) in the proximal ureteral calculi,94%(31/33) in the middle ureteral calculi,94%(102/108) in the distal ureteral calculi,respectively.The complication rate was 5% (8 cases).the stone-free rate of bladder calculi was 100%(12/12),no complication. Conclusion Ureteroscopic holmium:YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.
