【摘要】 目的提高输尿管阴性结石的诊治水平。方法 2003年8月至2008年8月采用输尿管镜下钬激光治疗输尿管阴性结石42例。经尿道输尿管镜直视下到达结石部位,采用钬激光腔内碎石治疗,同时消融息肉。结果手术时间15～60min(20.0±3.2min)。40例均一次治疗成功,2例上段结石被冲入肾盂,留置双J管后行ESWL治疗。术中未发生输尿管黏膜撕脱、输尿管穿孔、输尿管黏膜隧道等严重并发症。术后仅有轻微血尿,无低热、肾区疼痛等不适。36例随访3～24个月,平均7个月,均未发现结石残留及输尿管狭窄。结论输尿管镜下钬激光治疗输尿管阴性结石安全,疗效满意。更多还原

【Abstract】 Objective To improve the diagnosis and treatment of the ureteral radiolucent calculi.Methods From August 2003 to August 2008,42 patients with urinary tract radiotransparent calculi had been treated by holmium laser lithotripsy via ureteroscope.After reaching the stone under direct vision of transurethral ureteroscope,the cavity holmium laser lithotripsy was introduced to fragment the intraluminal stones and melt the polyps.Results The mean operation time of this series was 20 ± 3.2min(15~60 min).40 cases were removed completely in one session except 2 patients,whose upper calculi were flushed into the renal pelvis,indwelling double J tube underwent ESWL treatment.No ureteral mucosa avulsion,perforation,false passage and other severe complications occurred.Some of the patients had mild haematuria after the operation without fever or renal pain.36 cases had been followed up for 3 to 24 months(mean 7 months),and none of them had residual stones or ureteral stricture.Conclusion Holmium laser lithotripsy via ureteroscope is a safe and effective procedure for the treatment of urinary tract radiolucent calculi.更多还原
