Clinical Trial Summary

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.

Description:

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.
