Development of a New Two-Arm Transurethral Surgical System for En Bloc Resection of Bladder Tumor: A Preclinical Study.

To overcome the piecemeal nature of bladder tumor resection, en bloc resection of bladder tumor (ERBT) has been introduced. ERBT is difficult for surgeons to perform using the currently available system because it has only one arm. Herein, we aimed to develop a new transurethral surgical system to facilitate two-arm ERBT and to report the results of preclinical experiments using tumor phantoms.
