Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will compare the time required for a cystoscopy procedure in adult participants using the Redpine® Rflex endo(trademark) High-Definition Cystoscope or the site's standard of care reusable flexible cystoscope in participants requiring urethral stent removal.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This randomized study will compare the cumulative procedure time between cystoscopy performed with the Redpine® Rflex endo(trademark) High-Definition Cystoscope and the site's standard of care reusable flexible cystoscope in adult study participants requiring cystoscopy for visualization of and/or intervention on the urinary bladder. The study will evaluate the user experience and product performance during cystoscopic procedures. Participant experience, tolerance to the procedure, and any differences in adverse events between disposable and reusable scope will be evaluated. The hypothesis is that the RedPine cystoscope will perform as well as reusable scopes and will have a shorter cumulative procedure time.
