The RELIEF™ Ureteral Stent - Assessment of Retrograde Urinary Reflux and Distal Coil Bladder Position
United States24 participantsStarted 2021-06-15
Plain-language summary
Traditional ureteral stents are commonly used in renal and ureteral procedures, and their use is associated with many morbidities which can affect patients' quality of life. However, replacement of the distal portion of the stent with a thin material may reduce bladder irritative symptoms and allow the ureterovesical junction to coapt---thereby, reducing urinary reflux. The hypothesis is that the RELIEF stent will offer the same function of traditional ureteral stents with the added benefits of minimizing urinary reflux and reducing irritative bladder symptoms.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Ureteral stone of 5-25 mm measured on plain abdomen X-ray KUB (Kidney Ureter Bladder) or CT (computed tomography).
* Upper or middle third ureteral stricture.
Exclusion Criteria:
* Patients with distal ureteral obstruction
* Patients with urinary reflux
* Patients requiring bilateral surgical stone management procedure
* Intraoperative exclusion: Based on the urologist's discretion, if trauma has been induced to the distal ureter due to ureteroscopy maneuvers, these patients will be excluded.
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.
1This trial tested something called the RELIEF ureteral stent and looked specifically at bladder irritation symptoms like urgency, frequency, nocturia, and urine leakage — how do these side effects compare to what I might expect with a standard ureteral stent?
2The study also tracked changes in loin pain from a baseline score — based on the completed results, did the RELIEF stent actually reduce flank or back pain compared to conventional stents, and is that relevant to my specific type of ureteral obstruction?
3Since this trial is already completed, have the results been published or shared anywhere, and can you review the findings with me so I understand whether this stent design showed a real-world benefit for patients like me?
4The trial focused on bladder position of the stent's distal coil and urinary reflux — can you explain in plain terms what that means for day-to-day comfort, and whether that design consideration matters for my particular situation?
5Before considering whether this stent type is even an option for me, is there a standard treatment approach for my ureteral obstruction that I should try first, and how would that compare in terms of these same side effects the trial was measuring?

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.
