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 Results may not be published yet.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
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

Summary

Researchers compare two flexible scopes used to remove kidney or upper ureter stones through the urinary tract. One scope has built-in suction to pull out stone fragments and fluid during laser breaking; the other is the standard reusable scope without suction. The trial enrolls 70 adults with a single stone and tracks fever, inflammatory response, hospital stay, and whether stones are gone four weeks later on CT scan.

What this could mean

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

Active substance
A flexible ureterorenoscope with direct in-scope suction, a single-use camera-and-suction tube used to remove kidney stones
What this could lead to
If the suction scope works better, it could mean fewer infections and fewer repeat procedures for people having kidney stones removed.
What could go wrong
This is a small comparison of 70 patients at one hospital, so the results may not hold for other surgeons or stone types. Suction scopes are single-use and may cost more than reusable standard scopes.
