Reducing recurrence in non-muscle-invasive bladder cancer using photodynamic diagnosis and immediate post-transurethral resection of the bladder chemoprophylaxis.

Objective: The aim of this study was to evaluate the effect of fluorescence cystoscopy and immediate post-transurethral resection of the bladder (TURB) chemoprophylaxis on the risk of recurrence of non-muscle-invasive bladder cancer (NMIBC) under routine clinical conditions.

Materials And Methods: Fluorescence cystoscopy using hexyl-aminolevulinate and post-TURB chemoprophylaxis using mitomycin C were simultaneously introduced in an effort to reduce the recurrence of NMIBC. In total, 190 consecutive patients were enrolled over a 2 year period and followed as the intervention group; 216 patients treated over a 2 year period before introduction served as controls.
