Item Totally intracorporeal robot-assisted urinary diversion for bladder cancer (Part 1). Review and detailed characterization of ileal conduit and modified Indiana pouch(2021) Otaola, Hugo; Coelho, Rafael; Patel, Vipul; Orvieto, MarceloObjective: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.Item Totally intracorporeal robot-assisted urinary diversion for bladder cancer (part 2). Review and detailed characterization of the existing intracorporeal orthotopic ileal neobladder(2021) Otaola, Hugo; Seetharam, Kulthe; Patel, Vipul; Covas, Marcio; Orvieto, MarceloAbstract: To review the most used intracorporeal orthotopic ileal neobladder (ICONB) after radical cystectomy for bladder cancer and create a unified compendium of the different alternatives, including new consistent images. Methods: We performed a non-systematic review of the literature with the keywords "bladder cancer", "urinary diversion", "radical cystectomy", and "neobladder". Results: Forty studies were included in the analysis. The most frequent type of ICONB was the modified Studer "U" neobladder (70%) followed by the Hautmann "W" modified neobladder (7.5%), the "Y" neobladder (5%), and the Padua neobladder (5%). The operative time to perform a urinary diversion ranged from 124 to 553 min. The total estimated blood loss ranged from 200 to 900 mL. The rate of positive surgical margins ranged from 0% to 8.1%. Early minor and major complication rates ranged from 0% to 100% and from 0% to 33%, respectively. Late minor and major complication rates ranged from 0% to 70% and from 0% to 25%, respectively. Conclusion: The most frequent types of ICONB are Studer "U" neobladder, Hautmann "W" neobladder, "Y" neobladder, and the Padua neobladder. Randomized studies comparing the performance of the different types of ICONB, the performance in an intra or extracorporeal manner, or the performance of an ICONB versus ICIC are lacking in the literature. To this day, there are not sufficient quality data to determine the supremacy of one technique. This manuscript represents a compendium of the most used ICONB with detailed descriptions of the technical aspects, operative and perioperative outcomes, and new consistent images of each technique.
