Thulium Fiber Laser En-bloc Resection vs Conventional Transurethral Resection of Non-muscle-invasive Bladder Cancer

Ongoing efforts aim at overcoming the challenges of conventional transurethral resection of bladder tumor (TURBT) such as the high recurrence rate, difficulty of pathologic interpretation and complications including wall injury. Possible advantages may have en bloc resection of bladder tumor which was previously shown to be effective and safe technique. Use of novel thulium-fiber laser may also provide additional safety and efficacy of the resection. Objective. To prospective assess the safety and efficacy of Thulium-fiber en bloc resection of bladder tumor (Tm-fiber-ERBT) compared to TURBT.
