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 Results may not be published yet.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.

Summary

This study tested a new miniature endoscope called the 'Aircraft Nephroscope' for removing kidney stones. 216 patients underwent surgery with this device to see if it is safe and effective. The main goal was to check how many stones were completely removed and how many complications occurred.

What this could mean

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

Active substance
Aircraft Nephroscope (miniature endoscopic system)
What this could lead to
If successful, this could provide a safer and more efficient way to remove kidney stones, potentially reducing recovery time and complications.
What could go wrong
This is an early-stage device study with no comparison group, so benefits over standard scopes are unproven. Risks include infection, bleeding, or incomplete stone removal.
