输尿管镜下钬激光治疗输尿管阴性结石

Holmium:YAG Laser Lithotripsy Under Ureteroscope for Radiolucent Ureteral Calculi

目的:提高输尿管阴性结石的诊治水平。方法:对41例B超、静脉尿路造影(IVU)、CT等明确诊断或间接诊断为输尿管阴性结石的患者,行输尿管镜检及钬激光碎石治疗。结果:41例均成功解除梗阻,取得满意疗效,其中39例为一次性碎石成功,2例结石部分逆行入肾盂,术中术发生输尿管黏膜撕脱、输尿管穿孔等严重并发症。术后随访肾积水明显改善。结论:输尿管镜下钬激光碎石术是治疗输尿管阴性结石的理想方法之。

Objective：To investigate the effect, safety, and skills of holmium laser lithotripsy by ureteroscopy for radiolucent ureteral calculi. Methods：The ureteral radiolucent calculi can be diagnosed by combining B ultrasound, IVU and spiral CT scan. 41 patients with ureteral radiolucent calculi were treated by holmium laser lithotripsy via a ureteroscope. Results：The stone was removed completely in one session in all of the cases except in 2 patients, whose upper calculi were flushed into the renal pelvis. No ureteral mucosa avulsion, perforation and other severe complications occurred, hydronephrosis improved markedly or disappeared after operation. Conclusions： Holmium ： YAG laser lithotripsy under ureteroscope is an ideal treatment for the ureteral radiolucent calcul.
