Abstract

Objective: To review the most used robot-assisted cutaneous urinary diversion (CUD) after radical cystectomy for bladder cancer and create a unified compendium of the different alternatives, including new consistent images. Methods: A non-systematic review of the literature with the keywords "bladder cancer", "cutaneous urinary diversion", and "radical cystectomy" was performed. Results: Twenty-four studies of intracorporeal ileal conduit (ICIC) and two of intracorporeal Indiana pouch (ICIP) were included in the analysis. Regarding ICIC, the patients' age ranged from 60 to 76 years. The operative time to perform a urinary diversion ranged from 60 to 133 min. The total estimated blood loss ranged from 200 to 1 117 mL. The rate of positive surgical margins ranged from 0% to 14.3%. Early minor and major complication rates ranged from 0% to 71.4% and from 0% to 53.4%, respectively. Late minor and major complication rates ranged from 0% to 66% and from 0% to 32%, respectively. Totally ICIP data are limited to one case report and one clinical series. Conclusion: The most frequent type of CUD is ICIC. Randomized studies comparing the performance of the different types of CUD, the performance in an intra- or extracorporeal manner, or the performance of a CUD versus orthotopic ileal neobladder are lacking in the literature. To this day, there are not enough quality data to determine the supremacy of one technique. This manuscript represents a compendium of the most used CUD with detailed descriptions of the technical aspects, operative and perioperative outcomes, and new consistent images for each technique.
