Patients meeting eligibility criteria will be recruited from genitourinary cancer clinics at the University of Michigan Comprehensive Cancer Center. Patients undergoing initial consultation, active treatment, or surveillance after endoscopic or intravesical therapy will be identified and screened. Interested patients will be counseled by Dr. Lee or her designee, who will review the rationale and benefits of the study, the potential risks and probability of their occurrence, and the procedures to minimize these risks. Patients who wish to enter the study will be asked to sign a consent form that meets the requirements of the University of Michigan IRB. A signed copy of the patient consent will be entered into the medical record.
