RETRACTED: Randomized Trial of Narrow-band Versus White-light Cystoscopy for Restaging (Second-look) Transurethral Resection of Bladder Tumors

The author of this paper has requested that it be retracted because of an incorrect representation of the study methodology. Contrary to the manuscript contents, patients were randomly assigned to narrow band or white light cystoscopy in the order of their attendance, rather than in a permuted block allocation. Patients were individually consented for the clinical procedures, but not to a prospective randomized clinical trial where randomization occurred by permuted block. An appropriate waiver was obtained from the Institutional Review Board to analyze and publish anonymized data from the clinical database.
