目的探讨应用经尿道输尿管镜技术诊治输尿管结石的临床价值。方法对本院2004年6月~2005年6月,采用输尿管镜诊治的46例输尿管结石病例进行回顾性分析。结果经尿道输尿管镜取石术40例成功,取石治疗成功率为87.0%。发生并发症3例,占6.5%(3/46),其中输尿管撕脱1例,输尿管穿孔2例,另外术中置镜失败1例,结石上滑2例,都发生在应用输尿管镜取石的早期病例。辅以体外冲击波碎石(ESWL),3个月后随访结石均可排净,未发现肾积水、输尿管狭窄等。结论输尿管镜下取石是治疗输尿管结石尤其是中下段输尿管结石的一种安全、有效的方法,其成功率取决于操作经验、技术熟练程度及适应证的掌握。
Objective To investigate the clinical value of transurethral ureteroscopic diagnosis and treatment of ureteral calculi. Methods From June 2004 to June 2005, 46 cases of ureteral calculi treated by ureteroscopy were retrospectively analyzed. Results The transurethral ureteroscopic lithotomy was successful in 40 cases, and the success rate of stone removal was 87.0%. Complications occurred in 3 cases, accounting for 6.5% (3/46), including ureteral avulsion in 1 case, ureter perforation in 2 cases, another case failed to set the mirror in 1 case, stones in 2 cases, occurred in the application of ureteroscopic stone Early cases. Supplemented by extracorporeal shock wave lithotripsy (ESWL), after 3 months of follow-up stones can drain, did not find hydronephrosis, ureteral stricture. Conclusions Ureteroscopic lithotripsy is a safe and effective method for the treatment of ureteral calculi, especially in the lower and middle ureteral calculi. The success rate depends on the operating experience, technical proficiency and indications.
