目的:探讨改良后腹腔镜输尿管手术的技术方法以及在治疗输尿管疾病中的应用价值和效果。方法:回顾性分析2006年3月～2008年12月间应用改良后腹腔镜输尿管手术治疗的47例输尿管结石、腔静脉后输尿管、UPJ连接处梗阻、输尿管狭窄患者的临床资料。结果:47例手术均取得成功,平均手术时间96 min,术中出血20 ml,无手术相关并发症,无中转开放手术者。其中38例患者平均随访15个月,复查B超或IVU提示患侧输尿管通畅,同侧肾积水明显减轻,无吻合口狭窄、尿瘘、感染等并发症。结论:改良后腹腔镜输尿管手术简单易行,显著减少手术时间,效果确切,值得临床推广。 Objective: To explore the improved laparoscopic ureteral surgery techniques and methods in the treatment of ureteral diseases in the application of value and effectiveness. Methods: The clinical data of 47 patients with ureteral calculi, posterior vena cava ureter, UPJ junction obstruction and ureteral stricture treated with modified laparoscopic ureteral surgery between March 2006 and December 2008 were retrospectively analyzed. Results: All the 47 cases were successful. The average operation time was 96 minutes. The intraoperative blood loss was 20 ml. No operative complications were found and there were no patients undergoing open surgery. Among them, 38 patients were followed up for an average of 15 months. The review of B-ultrasound or IVU showed ipsilateral ureteral patency, ipsilateral hydronephrosis was significantly reduced, no anastomotic stenosis, urinary fistula, infection and other complications. Conclusion: The modified laparoscopic ureteral surgery is simple and easy, significantly reducing the operation time, the exact effect, worthy of clinical promotion.
