En Bloc Versus Conventional Resection of Primary Bladder Tumor (eBLOC): A Prospective, Multicenter, Open-label, Phase 3 Randomized Controlled Trial

We compared two techniques for removal of bladder tumors and found that tumor removal in a single piece, called en bloc resection, provides a better-quality specimen for pathology analysis and fewer complications in comparison to the conventional method. This trial is registered at ClinicalTrials.gov as NCT03718754.
