Background: Robot-assisted repair of benign ureteroenteric anastomotic strictures (UAS) provides an alternative to the open approach. We aimed to report short-, medium-, and long-term outcomes for robotic repair of benign UAS, and to provide a detailed video demonstration of critical operative techniques in performing this procedure robotically. Materials and Methods: Between January 2013 and September 2022, 31 patients from seven institutions who previously underwent radical cystectomy and subsequently developed UAS underwent robotic repair of UAS. Perioperative variables were prospectively collected, and postoperative outcomes were assessed. The surgery starts with a lysis of adhesions after previous surgery. Ureters are dissected, and the level of the stricture is identified. The ureter is then divided, and the stricture is resected. Finally, the ureter is spatulated and reimplanted with Nesbit technique after stenting with Double-J stents. In cases where both ureters show strictures, Wallace technique for reimplantation can be applied. Results: After robotic or open cystectomy, 31 patients had a total of 43 UAS at a median (interquartile range) follow-up of 21 (9-43) months. Median stricture length was 2.0 (1.0-3.25) cm, operative duration was 141 (121-232) minutes, estimated blood loss was 100 (50-150) mL, and length of hospital stay was 5 (3-9) days. One (3.2%) case was converted to open and one (3.2%) intraoperative complication occurred. Seven (22.6%) patients experienced postoperative complications, including four (12.9%) Clavien-Dindo grade 3 complications. No Clavien-Dindo grade 4 or 5 complications occurred. Stricture recurrence occurred in 2 (6.5%) patients. Conclusions: These results demonstrate that robotic repair of UAS is feasible and effective approach with outcomes in line with prior open series. Patient Consent Statement: Authors have received and archived patient consent for video recording and publication in advance of video recording of procedure.

膀胱切除术后尿流改道的机器人辅助修复输尿管肠狭窄：欧洲机器人泌尿科科学工作组的技术描述和结果。

背景：机器人辅助修复良性输尿管肠吻合口狭窄（UAS）提供了开放手术的替代方案。我们的目的是报告机器人修复良性无人机的短期、中期和长期结果，并提供机器人执行此手术的关键手术技术的详细视频演示。材料和方法：2013 年 1 月至 2022 年 9 月期间，来自 7 个机构的 31 名既往接受根治性膀胱切除术并随后开发 UAS 的患者接受了 UAS 机器人修复术。前瞻性收集围手术期变量，并评估术后结果。手术从上次手术后的粘连松解术开始。解剖输尿管，并确定狭窄的程度。然后将输尿管分开，并切除狭窄部分。最后，在双J支架置入支架后，用Nesbit技术刮开输尿管并重新植入。如果双侧输尿管均出现狭窄，可以应用华莱士再植技术。结果：机器人或开放式膀胱切除术后，31 名患者在中位（四分位距）随访 21（9-43）个月时总共出现 43 例 UAS。中位狭窄长度为 2.0 (1.0-3.25) cm，手术持续时间为 141 (121-232) 分钟，估计失血量为 100 (50-150) mL，住院时间为 5 (3-9) 天。1 例（3.2%）转开放，1 例（3.2%）发生术中并发症。7 例 (22.6%) 患者出现术后并发症，其中 4 例 (12.9%) Clavien-Dindo 3 级并发症。没有发生 Clavien-Dindo 4 级或 5 级并发症。2 名患者（6.5%）出现狭窄复发。结论：这些结果表明，无人机的机器人修复是可行且有效的方法，其结果与之前的公开系列一致。患者同意声明：在程序视频录制之前，作者已收到并存档患者对视频录制和发布的同意。
