The authors have newly devised a fluorescence cystoscope assembly. This fluorescence assembly is able to 1) confirm lesions in the bladder mucosa by fluorescence, 2) mark and cut the lesion with accuracy for histological survey. Moreover, this assembly is characterized by its exactness in cutting out the appropriate amount of specimen (bladder mucosa) and by its convenience in performing biopsy especially around the bladder neck.
