Non-muscle-invasive bladder cancer (NMIBC) commonly recurs, requiring invasive and costly transurethral resection of bladder tumor (TURBT). A meta-analysis of seven trials published in 2004 demonstrated that intravesical chemotherapy (IVC) following TURBT reduces recurrences. Despite European Association of Urology endorsement, adoption of this practice has been modest. ⋯ Our updated meta-analysis supports that IVC prolongs RFI and reduces ERs of NMIBC when administered immediately after TURBT. However, contemporary methodology suggests low evidence quality for examined outcomes. Thus RCTs with careful randomization and blinding are still warranted to clarify the usefulness of immediate postoperative IVC in this population.
