Replacing Invasive Cystoscopy With Urine Testing for Non-muscle Invasive Bladder Cancer Surveillance
The purpose of this research is to determine whether bladder cancer monitoring can be improved by replacing some cystoscopy procedures with urine testing. Specifically, this study examines whether there are any differences in urinary symptoms, discomfort, number of invasive procedures, anxiety, complications, cancer recurrence or cancer progression when some cystoscopy procedures are replaced with urine testing.

⁃ recurrent low grade non-invasive urothelial carcinoma
• Stated willingness to comply with all study procedures and availability for the duration of the study
