Suspicious or confirmed patients with bladder cancer. 3. Age 18 or older. Exclusion Criteria: 1. Gross haematuria. (Note: Gross haematuria is defined as a heavy bladder bleed resulting in marked amounts of blood in the urine, which may visually limit cystoscopy. Where the haematuria is light, the patient should not be excluded, if in the investigator's opinion, rinsing and/or electro-cautery during cystoscopy will alleviate the possible interference with cystoscopy). 2. Patients who have received BCG immunotherapy or intravesical chemotherapy within the past 6 weeks prior to the procedure. 3. Porphyria. 4. Known allergy to hexaminolevulinate hydrochloride or a similar compound. 5.
