The dual-channel flexible ureteroscope provides similar deflection characteristics to the current single-channel scope. Deflection and flow characteristics are superior, however, when larger or multiple simultaneous instruments are used in the working channel. These benefits may facilitate the development and implementation of novel endoscopic procedures.
A cavernosal nerve-sparing robot-assisted approach to radical cystectomy allows for recovery of potency without sacrificing oncologic outcomes even with higher risk disease as compared to historical open or laparoscopic series. Further studies are required to help elucidate why some men have better recovery in this setting than others.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
