Plain-language summary
Flexible ureteroscopy is characterized as first-line therapy for renal stones \< 2 cm in size. Stones are commonly treated with dusting or fragmentation techniques which requires passage of stone fragments after surgery. Quoted stone free rate after flexible ureteroscopy is approximately 40-60% with a dusting technique. Residual fragments are often under 1mm in size and can layer in the lower pole of the kidney, complicating spontaneous stone passage. Improving the stone free rate after surgery decreases the need for secondary surgeries and decreases risk of future stone events.
Numerous techniques have been proposed to increase stone passage including positional changes and percussion therapy. To date, there is overall limited data a lack of techniques that can be readily available in the outpatient setting, easily added to scheduled appointments, reproducible results and well tolerated by patients.

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
