Patients with a visual diagnosis of bladder cancer following cystoscopy will be approached and asked to consent for this study. Consenting participants will be provided with a urine sample collection kit and asked to provide a urine sample. Samples can be provided at home and posted to the receiving lab using the stamped addressed envelope. The urine sample must be obtained before TURBT and following TURBT, patients with NMIBC who require surveillance cystoscopy will be asked to provide a urine sample at 3 monthly intervals for up to 2 years.
