Transurethral En Bloc Versus Standard Resection of Bladder Tumour: A Multi-centre Randomised Controlled Trial (EB-StaR Study).


Condition: Bladder Cancer

Intervention:

  • Device: Bipolar transurethral standard resection
  • Device: Bipolar transurethral en bloc resection

Purpose: Conventionally, transurethral standard resection (SR) of bladder tumour is performed in a piecemeal manner. Transurethral en bloc resection (EBR) has been described as an alternate surgical technique in bladder tumour resection. By preventing tumour fragmentation and ascertaining complete tumour resection by histological assessment of the EBR specimen, we hypothesized that EBR could reduce disease recurrence as compared to SR.
