PURPOSE We determined whether the sensitivity of detecting dysplasia or early bladder cancer can be improved by 5-aminolevulinic acid induced porphyrin fluorescence. MATERIALS AND METHODS A 3% 5-aminolevulinic acid solution was instilled intravesically before cystoscopy in 104 patients. The 5-aminolevulinic acid induced porphyrin fluorescence was excited by violet light from a krypton ion laser (wavelength 406.7 nm.). RESULTS The sensitivity of the fluorescence cystoscopy (96.9%) was… CONTINUE READING
