(UroToday.com) At the non-muscle invasive bladder cancer (NMIBC) treatment and prognosis session at the European Association of Urology 2021 annual meeting Dr. Pietro Diana presented interim results of a single-center prospective randomized trial assessing en-bloc versus conventional transurethral resection of bladder tumors (TURBT). TURBT is considered the gold standard in the diagnosis and risk stratification of bladder cancer, however, en-bloc resection of bladder tumors has been proposed to improve resection quality. Recently, the International Collaborative Consensus Statement on en-bloc resection of bladder tumor underlined the lack of high-quality prospective studies precluding the achievement of solid conclusion for en-bloc resection1. The aim of this study was to compare TURBT and en-bloc resection of bladder tumors in terms of pathological diagnosis, surgical, and oncological outcomes.
