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 Results may not be published yet.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
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether a 3D navigation system can help surgeons remove kidney tumors more precisely during robot-assisted surgery. The system uses CT and MRI scans to create a 3D model, and a small sensor attached to the kidney tracks movement. The goal was to see if the navigation helps remove only the planned amount of tissue, sparing healthy kidney. Twenty patients participated, and the main measure was how closely the actual removed tissue matched the planned volume.

What this could mean

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

Active substance
Image-guided surgery (3D model and electromagnetic tracking)
What this could lead to
If successful, this navigation tool could help surgeons remove kidney tumors more precisely, saving more healthy kidney tissue and expanding the use of kidney-sparing surgery.
What could go wrong
This is a small, early feasibility study with only 20 patients. The navigation may not improve outcomes in real-world practice, and technical issues could limit its use.
