What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This trial tests whether removing the urinary catheter within 24 hours after a kidney transplant is as safe as keeping it longer. The goal is to see if early removal reduces urinary tract infections without increasing the risk of urine leaks or narrowing of the ureter. About 120 kidney transplant recipients will be randomly assigned to early or delayed catheter removal, and their outcomes will be compared over the following year.

What this could mean

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

Active substance
Urinary catheter removal (procedure)
What this could lead to
If early removal proves safe, it could reduce urinary tract infections and shorten recovery after kidney transplant, improving long-term graft health.
What could go wrong
Early removal might increase the risk of urine leaks or strictures, and the trial is relatively small, so results may not be definitive.
