title: Clinically occult bladder cancer diagnosis. Trial using ultraviolet cystoscopy.
abstract: Ultraviolet cystoscopy was used to demonstrate flat cancerous and precancerous bladder lesions by two techniques based on different principles: the loss of epithelium blood group antigenic expression using immunofluorescence reaction, and submucosa neoangiogenesis after fluorescein intravenous injection. The results obtained with these two techniques were disappointing, but do not preclude the use of ultraviolet cystoscopy in this type of study.
