Abstract
There has been growing interest in intracorporeal techniques to urinary diversion during cystectomy in the modern area. There is little high-quality evidence that this technique is superior to extracorporeal diversion in patients who are obtaining an orthotopic intracorporeal neobladder urinary diversion. This study describes the proposed advantages and disadvantages of intracorporeal orthotopic neobladder urinary diversion and expert opinion on preference. METHODS: We reviewed the literature for all studies discussing the outcomes and advantages of intracorporeal orthotopic neobladder urinary diversion, including those comparing the intracorporeal and extracorporeal approach. The studies were reviewed and these findings were summarized based on categories of the proposed advantages and disadvantages of the intracorporeal approach. We provided an assessment of the claims made in favor of the intracorporeal approach and discussed advantages of the extracorporeal approach that may persuade even the most experienced robotic surgeons to lean away from the former. RESULTS AND CONCLUSIONS: Herein we review the studies that propose advantages of the intracorporeal diversion, as well as the studies that do not demonstrate any advantage to this approach. Some of the proposedadvantages addressed include decreased stricture rate, lower complications and shorter hospitalization. Furthermore, we address the issues of the steep learningcurve and the impact on resident education. We conclude that the proposed benefits of an intracorporeal approach to urinary diversion are not substantiated and it is the preference of the authors to primarily perform extracorporeal urinary diversions.
