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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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

Details not published

Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether a laser imaging technique, called laser speckle contrast imaging, can predict how well a new kidney will work after a transplant. The technique measures blood flow in the tiny blood vessels of the kidney during surgery. Researchers will compare these images with the kidney's function in the days after the operation to see if the imaging can spot early signs of problems.

What this could mean

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

Active substance
laser speckle contrast imaging (LSCI) device
What this could lead to
If successful, this imaging technique could help doctors predict early kidney function after transplant, potentially improving patient care.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The results may not apply to all transplant patients, and the imaging technique's predictive value is still uncertain.
