Open and Robotic Uretero-enteric Stricture Repair: Early Outcomes and Complications.

To characterize our single institutional experience with robotic and open uretero-enteric stricture (UES) repair. We queried our ureteral reconstructive database for UES repair between 01/2017 and 10/2023. Patients with <3 months follow-up were excluded. Prior to surgery, patients underwent ureteral rest (4 weeks) with conversion to nephrostomy tube. Clinical characteristics, complications, reconstructive success (uretero-enteric patency), need for repeat intervention, and renal function were assessed in patients undergoing open and robotic UES reconstruction. Of 50 patients undergoing UES repair during the study period, 45 were included for analysis due to complete follow-up (34 [76%] robotic and 11 [24%] open repair). UES repair was performed in 50 renal units a median of 13 months (interquartile range 7-30) from index surgery, and most often involved the left renal unit (34/50; 68%). Compared with robotic, open cases were significantly more likely to have undergone open cystectomy (100% 68%, = 0.04), have longer strictures (median 4 1 cm, < 0.001), require tissue substitution (27% 3%, = 0.04), and have lengthier postoperative hospitalization (5 2 days, < 0.001). There was no significant difference in total operative time (410 322 minutes) or 30d major complications (18% 21%). At a follow-up of 13 months, per patient reconstructive success was 100% (11/11) for open and 97% (33/34) for robotic, respectively. In select patients with short UES unlikely to require advanced reconstructive techniques, a robotic-assisted approach can be considered. Careful patient selection is associated with limited morbidity and high reconstructive success.
