Abstract: Objective To evaluate the value of photodynamic diagnosis for early detection of bladder cancer using narrow band imaging fluorescence cystoscopy. Methods A total of 28 cases of painless hematuria underwent narrow band imaging(NBI) endoscopy and biopsy. The procedure was as follows: biopsies were taken from lesions that were either fluorescing or nonfluorescing using endoscopy by NBI system) and then TUR was performed on them. Results Of the 28 cases, 79 biopsies were taken. Histopathologic examination showed that 32 of them were of urothelial cell carcinoma. Compared with white light cystoscopy, NBI had a sensitivity of 100% (32/32) ,flat small fluorescence positive lesions were found in peritumoral or other regions, which could not be detected by white light cystoscopy. Conclusion Photodynamic diagnosis using NBI fluorescence cystoscopy is useful for detection of early bladder cancer.
