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.
Drug: Hexaminolevulinate HCL
Intravesical instillation of 100 mg hexaminolevulinate HCL will be performed via foley catheter at the initiation of the procedure. Although NIRF is more sensitive than bluelight cystoscopy, the current FDA approved dose will be used. Hexaminolevulinate has a favorable safety profile at this dose.
Device: Near Infrared Fluorescence (NIRF)
NIRF is a highly sensitive multi-spectral imaging modality that speeds the detection of bladder cancer fluorescence after infusion of hexaminolevinulate.
- Minimal Dwell Time [ Time Frame: Day 1 ]The minimum time needed to observe the tumors during transurethral resection of bladder tumor (TURBT).
