    "abstract": "Benign ureterointestinal anastomotic stricture (UIAS) is a recognized long-term complication following radical cystectomy with urinary diversion (UD). The incidence of UIAS following robotic-assisted radical cystectomy varies, with reported rates ranging from 6.5%-25.3%.\nFrom May 2020-March 2023, 6 patients underwent surgery. The mean age was 62\u00a0years (range 49-68\u00a0years). Among these, 2 patients received conduits in open technique and 4 were provided with robotic neobladders. The strictures were located as follows: 2 on the left side, 2 on the right, and 2 on both sides. The average time to stricture formation in the series was 4.5\u00a0months. The case presented involves a 49-year-old man who developed a left ureteroileal anastomotic stricture (UIAS) 6\u00a0months following robot-assisted radical cystectomy and neobladder creation. The obstruction was managed initially with nephrostomy tube drainage. The surgical technique employed is demonstrated in a step-by-step manner. Standard Da Vinci surgical instruments were used. The patient was positioned in a 30\u00b0 Trendelenburg position, with port placement similar to that in robotic prostatectomy. The pneumoperitoneum was established through a supraumbilical mini-laparotomy using the Hasson technique. Adhesions around the neobladder were carefully freed. Subsequently, the affected ureter and the stricture were identified and localized. This was achieved by intraluminal application of 10\u00a0mL of indocyanine green solution (2.5\u00a0mg/mL concentration) through the nephrostomy catheter. The ureter was mobilized as needed. The ureteral stricture was identified and then fully excised. To exclude any malignancy at the ureteral margin, a frozen section analysis was conducted. The ureter was then spatulated. Reanastomosis between the ureter and neobladder was performed using a continuous 4-0 Stratafix suture. A double-J ureteral catheter was inserted to secure the anastomosis, and the anastomosis was completed over this catheter.\nThe mean operative time at the robotic console was 122\u00a0minutes, ranging from 80-160\u00a0minutes, and the mean blood loss was 42\u00a0mL, within a range of 50-100\u00a0mL. Intraoperative frozen sections revealed no evidence of malignancy in all cases. No postoperative complications exceeding Clavien-Dindo grade 3 were observed. Two patients were treated for symptomatic urinary tract infections. The median length of stay in the hospital was 4\u00a0days, with a range of 2-7\u00a0days. Median times for cystography with transurethral catheter removal and double-J catheter removal were 15 postoperative days (range: 12-27) and 23 postoperative days (range: 17-37), respectively. No recurrence of the condition was observed during a mean follow-up period of 23\u00a0months (range 6-40\u00a0months).\nThe robotic approach represents a viable, minimally invasive alternative to conventional open surgery for the reconstruction of UIAS following urinary diversion. The surgical outcomes are comparable to those of open surgery, with the added benefits of a minimally invasive approach, including reduced blood loss and shorter hospital stays.",
