China50 participantsStarted 2025-05-01

Plain-language summary

The purpose of this clinical study is to evaluate the safety and efficacy of the Sten® Laparoendoscopic Surgical System C1000 for benign ureteral reconstruction surgery. This is a single-arm, open-label, prospective, non-randomized cohort study. Eligibility criteria for recruitment to this study included how to include labeling: (1) patients aged ≥18 years and ≤80 years, male and female; (2) patients who need to undergo upper urinary tract repair surgery; (3) patients who are suitable for ureteral reconstruction surgery as confirmed by the investigator; (4) subjects voluntarily participating in the clinical trial and agreeing to, or their guardian agreeing to, and signing an informed consent form; (5) willingness to cooperate with and complete the trial follow-up and related examinations. The research subjects of this project were recruited openly, and the patients were enrolled after being informed of the study-related information, risks and benefits by the project participants and then screened to meet the enrollment criteria. A total of 50 patients will be enrolled. The study objectives and endpoints include the following: primary endpoints: (1) the rate of surgical non-referral (2) the success rate of surgical treatment; secondary endpoints: (1) the loading time (2) the operating time of the surgeon (3) the estimated intraoperative blood loss (4) the postoperative patient's pain scores (5) the evaluation of the physiological load of the surgeon (6) the evaluation of the mental load of the surgeon (7) the rate of intraoperative transfusion (8) the duration of the hospital stay after the operation (9) the evaluation of physician satisfaction (9) the evaluation of physician's satisfaction). (9) Physician satisfaction rating (10) Overall postoperative complication rate (11) Adverse events and serious adverse events (12) Device defects (13) Postoperative readmission rate (14) Reoperation rate (15) Mortality rate. The expected overall duration is 9 months, with an expected enrollment time of 6 months and a subject follow-up time of approximately 3 months.

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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.
