[ Objective ] To investigate the clinical experience of retroperitoneal laparoscopic treatment of duplex kidney and uretal duplication.[Methods] We have diagnosed 2 patients suffering from renal duplication and uretal duplication. They were both confirmed by B-ultrasonic, CT, CTU. Retroperitoneal laparoscopic nephrectomy and uretereetomy was performed, and ureteral orifice cyst was held. [ Results ] Two operations were successfully carried out, and the average time was 110 minutes, the average bleeding volume was 100 mL, no post-operative complications occurred, and the hospital stay was 15 days. A post-operation check on renal function and B-ultrasonic administered 1 month after their procedures presented no obvious abnormality with them. [ Conclusions ] Retroperitoneal laparoscopic treatment for duplex kidney and uretal duplication is safe, and feasible, and with less trauma,less complications.%目的 探讨后腹腔镜治疗重复肾、重复输尿管的临床体会.方法 诊治2例左侧重复肾及重复输尿管患者,均经过超声、CT及CT尿路造影(CTU)证实.该组2例病例均行后腹腔镜左侧重复肾及重复输尿管切除术,其中1例输尿管口囊肿予以旷置.结果 2例病例手术过程顺利.手术平均时间为110 min,平均出血量为100 mL.2例病例术后均未出现并发症,平均住院时间为15d.术后1个月复查肾功、B超均未见明显异常.结论 后腹腔镜治疗重复肾及重复输尿管安全易行,创伤小,并发症少.
