What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at why some people have a hard time tolerating a ureteral Double-J stent, a small tube placed in the ureter to help urine drain. Researchers will ask 200 adults who need this stent to fill out a questionnaire about their symptoms, both while the stent is in place and after it is removed. The goal is to identify factors that predict poor tolerance, which could help doctors offer better care to patients at higher risk.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Questionnaires (USSQ) to assess stent tolerance
What this could lead to
If successful, this could help doctors predict which patients will struggle with a Double-J stent and offer better support or alternatives.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The results depend on patients accurately completing questionnaires, and the findings may not apply to everyone.
