If no tumours are visible with "normal" white light cystoscopy but the cytology is positive, one may use photodynamic diagnosis or narrow band imaging to try to detect the tumour. One can also perform a "mapping biopsy", where biopsies are taken blindly from high predilection areas. | If no tumours are visible with "normal" white light cystoscopy but the cytology is positive, one may use photodynamic diagnosis or narrow band imaging to try to detect the tumour.

== Transurethral resection == | |||
If a bladder tumour is visible on cystoscopy, transurethral resection of bladder (TUR-B), also called transurethral resection of bladder tumour (TURBT) may be performed, which is both diagnostic and therapeutic. This involves resecting the entire visible tumour by cystoscopy. | |||
