"En Bloc" Resection of NMIBC: a Prospective， Single Centre，Randomized Study

The traditional method of choice for intravesical resection of bladder tumors is conventional transurethral resection of bladder tumor (cTURBT). However, there has long been an ambition to overcome its biggest limitation, tumor fragmentation. Possible consequences include cell seeding and poor specimen quality, including missing detrusor muscle, thermal tissue damage, and tissue fragmentation. En bloc resection of bladder tumor (ERBT) represents an alternative technique for resection of bladder tumors. There is no doubt that ERBT has huge potential. ERBT provides specimens of high quality that are easy for pathologists to read. In theory, this may sustainably change the view on secondary resection, lead to faster decisions on subsequent treatments, and influence patient prognosis. Thus, there is an urgent need to compare ERBT with cTURBT in a thoroughly planned trial.
