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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial is testing whether a minimally invasive procedure called flexible ureteroscopy can safely and effectively break up and remove large kidney stones (2 cm or larger) in children under 14. Using a thin, flexible scope and a laser, doctors aim to fragment the stones into smaller pieces that can pass naturally. The study will measure how many children become completely stone-free and how long the procedure takes, to see if this approach is a good alternative to more invasive surgery.

What this could mean

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

Active substance
Flexible ureteroscopic stone disintegration using a single-use flexible ureteroscope and Holmium laser
What this could lead to
If successful, this could establish a minimally invasive option for treating large kidney stones in children, potentially reducing the need for more invasive surgery.
What could go wrong
This is a single-arm study without a comparison group, so results may not be definitive. Risks include incomplete stone clearance, bleeding, infection, or injury to the urinary tract.
