Comparison of Flexible & Navigable Suction Ureteral Access Sheath vs. Antegrade Suction in Retrograde Flexible Ureteroscopy for Lower Calyceal Stones
120 participantsStarted 2025-03-30
Plain-language summary
This randomized controlled trial aims to compare the efficacy and safety of two suction techniques during retrograde flexible ureteroscopy (FURS) for lower calyceal renal stones measuring 1.5-2 cm. The study evaluates Flexible \& Navigable Suction Ureteral Access Sheath (FANS) versus Antegrade Suction (via percutaneous access) in improving stone-free rates (SFR), reducing operative time, and minimizing complications such as bleeding, ureteral injury, and infection. A total of 120 adult patients will be randomized into two groups, undergoing either flexible ureteroscopy (FURS) with Flexible \& Navigable Suction Ureteral Access Sheath (FANS) or flexible ureteroscopy (FURS) with antegrade suction, at Banha University Faculty of Medicine.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
