En bloc resection of bladder tumors: indications, techniques, and future directions.

Purpose of Review: En bloc resection of bladder tumor (ERBT) is an innovative new surgical technique, the use of which is becoming increasingly widespread. In this review, we analyze the recent literature and explore new developments, which may impact the future role of en bloc bladder surgery.
Recent Findings: ERBT increases the frequency with which detrusor muscle is present in the specimen (to 95%) and offers a significant improvement in the quality of the resection specimen, thereby helping with T1 substaging. Furthermore, the laser treatment reduces the rate of obturator nerve-related bladder perforation.
Summary: ERBT represents a considerable advancement in the surgical management of nonmuscle-invasive bladder cancer. It delivers excellent oncological results and is a well tolerated procedure.
Video: In the accompanying video, we shortly report the different modalities and energy sources used for bladder cancer resection. The three strategies are currently employed at the Fundació Puigvert (Barcelona). VIDEO ABSTRACT:.
