- Planned transurethral resection of bladder tumor in the operating room.
- Ability to give informed consent.
- Willing to spend time for the study
- Men or women (age 18 or older)
- Any racial or ethnic origin
Exclusion Criteria:

Arms of the Study
Arm 1
Experimental
Hexaminolevinulate HCL with Near Infrared Fluorescence (NIRF)
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.
