Narrow band imaging versus white light cystoscopy alone for transurethral resection of non‐muscle invasive bladder cancer

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of white light cystoscopy (WLC)‐ and narrow band imaging (NBI)‐ guided transurethral resection of bladder tumor (TURBT) compared to WLC‐guided TURBT alone in the treatment of non‐muscle invasive bladder cancer (NMIBC)
