Group Intervention Description Hexaminolevinulate HCL with Near Infrared Fluorescence (NIRF) Hexaminolevulinate HCL During the transurethral resection of the bladder procedure, the bladder will initially be examined in a systematic meridian fashion. Suspicious tumors identified by white light only, NIRF only, and both will be identified. If intense fluorescence is observed in the initial patient(s) at 10 min, dwell duration will be reduced to 5 min for the next patient(s); if abundant fluorescence is detected there as well, dwell duration will be shortened again to 2.5 min. At least three patients will be studied at each duration to document intense fluorescence before proceeding to shorter instillation durations in subsequent patients.
