简要总结
This multi-center trial is being completed to compare patient outcomes related to the Imajin silicone stent in comparison to non-silicone polyurethane stents after ureteroscopy.
Eligible participants will be enrolled and randomly assigned to receive the Imajin silicone stent or a non-silicone stent. In addition, the participants will complete questionnaires and have follow-up information collected (approximately 60 days after surgery).
The trial hypothesizes that a ureteral stent made of silicone, will have superior outcomes when compared to non-silicone stents.

结局指标
主要结局
Change in Patient-Reported Outcomes Measurement Information System (PROMIS®) Scores of Pain-intensity at 7 to 10 Days
时间窗: Baseline, 7 to 10 days: Participants can fill out the survey at any time between 7 to 10 days after surgery.
This is a 3-item survey which participants select a response for each item from 1=no pain to 5=very severe for intensity of their pain. The sum of responses is then converted into a T-score that ranges from 36.3 to 81.8, with higher scores indicating worse pain intensity. Change is defined as the difference in T-score from baseline to 7-10 days after surgery.
Change in Patient-Reported Outcomes Measurement Information System (PROMIS®) Scores of Pain-interference at 7 to 10 Days
时间窗: Baseline, 7 to 10 days: Participants can fill out the survey at any time between 7 to 10 days after surgery.
This is a 6-item survey which participants select a response for each item from 1=not at all to 5=very much for how much pain interfered with their life. The sum of responses is then converted into a T-score that ranges from 41.0 to 78.3, with higher scores indicating worse pain interference. Change is defined as the difference in T-score from baseline to 7-10 days after surgery.
次要结局
- Change in National Institutes of Health (NIH) Lower Urinary Tract Dysfunction Research Network (LURN) Symptoms Index (SI)-10 Scores at 7 to 10 Days(Baseline, 7 to 10 days: Participants can fill out the survey at any time between 7 to 10 days after surgery.)
- Change in Patient-Reported Outcomes Measurement Information System (PROMIS®) Scores of Pain-intensity at 4 to 6 Weeks(Baseline, 4 to 6 weeks: Participants can fill out the survey at any time between 4 to 6 weeks after surgery.)
- Change in Patient-Reported Outcomes Measurement Information System (PROMIS®) Scores of Pain-interference at 4 to 6 Weeks(Baseline, 4 to 6 weeks: Participants can fill out the survey at any time between 4 to 6 weeks after surgery.)
- Change in NIH LURN SI-10 Scores at 4 to 6 Weeks(: Baseline, 4 to 6 weeks: Participants can fill out the survey at any time between 4 to 6 weeks after surgery. Baseline, 4 to 6 weeks: Participants can fill out the survey at any time between 4 to 6 weeks after surgery.)
- Composite Healthcare Utilization Metric Within 30 Days (WinRatio)(up to 30 days)
- Abnormal Imaging Findings Within 60 Days(up to 60 days)
- Stone-free Rates Within 60 Days(up to 60 days)
