目的:探讨钬激光腔内治疗泌尿系结石的有效性及安全性。方法:2005年10月至2006年2月采用钬激光治疗泌尿系结石36例,其中输尿管结石28例,膀胱结石8例。对钬激光的有效性及安全性与气压弹道碎石术进行分析比较。结果:36例中33例单次手术碎石成功,单次手术结石粉碎率达92%(33/36)。2例结石在钬激光碎石过程中移位于肾盏,术后行体外冲击波碎石术治疗。1例因输尿管狭窄进镜失败改为开放手术。结论:钬激光碎石术治疗泌尿系结石安全、有效,尤其适用于输尿管上段结石、结石合并息肉形成以及体外冲击波碎石无效的患者,效果明显优于气压弹道碎石法。
Objective: To investigate the efficacy and safety of holmium laser in the treatment of urinary calculi. Methods: From October 2005 to February 2006, 36 cases of urolithiasis were treated with holmium laser, including 28 cases of ureteral stones and 8 cases of bladder stones. The effectiveness and safety of holmium laser were compared with pneumatic lithotripsy. Results: Thirty-three cases of single operation in 36 cases were successful. The rate of single operation was 92% (33/36). 2 cases of stones in the holmium laser lithotripsy shift in the calyx, postoperative extracorporeal shock wave lithotripsy. A case of ureteral stricture into the mirror failed to open surgery. Conclusion: Holmium laser lithotripsy is safe and effective for the treatment of urinary calculi. It is especially suitable for patients with upper ureteral calculi, polyp formation of stones and invalid extracorporeal shock wave lithotripsy. The effect is superior to that of pneumatic lithotripsy.
