Abstract：
OBJECTIVE: This study was performed to evaluate the outcome of complete retroperitoneal laparoscopic nephroureterectomy with bladder cuff excision (RLNU-BCE), which is performed to treat urothelial carcinomas in the renal pelvis or in the ureter higher than the crossing of the common iliac artery without patient repositioning.
METHODS: We retrospectively analyzed the clinical data of 48 patients with upper tract urothelial carcinoma who underwent complete RLNU-BCE in our institution from May 2017 to September 2019.
RESULTS: RLNU-BCE was successfully performed in all 48 patients. The median operation time was 110 minutes [interquartile range (IQR), 100-130 minutes], and the median postoperative anesthesia recovery time was 10 minutes (IQR, 7-15 minutes). The median postoperative hospitalization period was 5 days (IQR, 4-6 days). Pathologic examination revealed that the margin of all resected specimens was negative. After a median follow-up of 13 months (IQR, 7-20 months), no local recurrence or distant metastasis was found. No complications occurred during follow-up.
CONCLUSIONS: Based on our experience with this technique, RLNU-BCE deserves application and promotion in clinical practice. Long-term comparative studies are required to confirm its superiority over other techniques.

摘要：
目的：本研究旨在评估后腹腔镜下膀胱袖状切除术（RLNU-BCE）的结果，这是为了治疗肾盂或输尿管上的尿路上皮癌而不是患者重新定位。
方法：回顾性分析2017年5月至2019年9月在我院行完全RLNU-BCE的48例上尿路尿路上皮癌患者的临床资料。
结果：RLNU-BCE在所有48例患者中均成功完成。中位手术时间为110分钟[四分位距（IQR），100-130分钟]，中位术后麻醉恢复时间为10分钟(IQR，7-15分钟）。术后中位住院时间为5天(IQR，4-6天）。病理检查显示所有切除标本的边缘均为阴性。经过13个月的中位随访（IQR，7-20个月),未发现局部复发或远处转移。随访期间无并发症发生。
结论：根据我们对这种技术的经验，RLNU-BCE值得临床应用和推广。需要进行长期比较研究，以确认其优于其他技术。
