Patients randomized to the experimental group will receive flexible ureteroscopy with the Storz Flex-XC1 disposable flexible ureteroscope.~Data will be collected and stored electronically in REDCap. Quality assurance steps will include testing of the database, including any potential data calculated by command functions within REDCap~Scope performance survey will be administered with REDcap.
This study is designed to provide an evaluation of currently available disposable flexible ureteroscopes in real-world conditions. Due to high re-processing costs associated with re-usable flexible ureteroscopes, there has been a demand for Urologic device manufacturers to provide single-use flexible ureteroscopes.
