Introduction Surgical intervention is the treatment of choice in patients with urachal carcinoma. Due to complications and to reduce hospital stay from open surgery, minimally invasive approaches are desirable. Nowadays, robotic‐assisted surgery has become increasingly popular, and robot‐assisted cystectomy can be performed in patients with urachal carcinoma with low complication rates. Methods We performed a systematic review to search for studies that evaluated patients who underwent robotic‐assisted surgery for urachal carcinoma. The outcomes of interest were the type of cystectomy performed, whether there was umbilicus resection, total operative time, console time, intraoperative complications, estimated blood loss, postoperative complications, time of hospitalisation, positive surgical margins and the presence of documented tumour recurrence. Results In this study, we evaluated three cohorts comprising a total of 21 patients. The median follow‐up period ranged from 8 to 40 months. Medium age was between 51 and 54 years, with a majority (63.1%) being male. One patient (5.2%) underwent a radical cystectomy, and 19 patients (94.7%) underwent to partial cystectomy. Umbilical resections were performed in all cases, and pelvic lymphadenectomy in 14 cases (73.6%). Recurrence occurred in three patients at a median of 17 months postoperation, two cases in the trocar insertion site. Additionally, there was one death, which was attributed to postoperative cardiovascular complications. Conclusion Robotic‐assisted partial cystectomy has a low incidence of adverse outcomes in patients with urachal carcinoma. Controlled studies, ideally randomised, are warranted to establish the comparative efficacy and safety of the robotic‐assisted cystectomy approach relative to open surgery.
