<bold>Background: </bold>Aim of the study was to present the surgical techniques and the postoperative outcomes in women treated with robotic excision for deep endometriosis involving the urinary tract.<bold>Materials and Methods: </bold>We retrospectively reviewed the prospectively recorded clinical data of women consecutively undergoing minimally invasive treatment for complex endometriosis involving urinary tract in our center between January 2012 and June 2018. All the patients received a preoperative multidisciplinary evaluation with the general surgeon, the gynecologist and the urologist due to the frequent concomitant involvement of bowel and genital system. Patients undergoing robotic surgery were treated with the Si or Xi da Vinci surgical system.<bold>Results: </bold>A total of 74 consecutive patients were enrolled. Twenty-eight (37.8%) patients underwent conventional laparoscopy and 46 (62.2%) robotic surgery. Only patients treated with robotic approach were considered for the final analyses. Overall, 17 (36.9%) patients were treated with partial cystectomy, 13 (28.3%) with ureteral reimplantation, 10 (21.7%) patients were treated with ureteral lysis, 4 (8.7%) with removal of bladder endometrial node without opening the mucosa layer and 2 (4.3%) with ureteral end-to-end anastomosis. Concomitant involvement of bowel and genital system was registered in 14 (30.4%) and 32 (69.5%) patients, respectively. No conversions to laparotomy were recorded. Overall, 5 (10.9%) patients experienced postoperative complications, of which only one was a major complication (Clavien 3b). At a median follow-up of 31.3 (IQR 17.6-43.3) months, 4 (8.7%) patients experienced disease recurrence at the level of urinary tract.<bold>Conclusions: </bold>Robotic excision of urological endometriosis represents a safe and effective treatment option, since a limited rate of surgical complications was recorded even in cases of multi-organ disease.
