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 Results may not be published yet.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.

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.

Summary

This study compares two ways to use a laser to break up bladder stones in children: dusting (turning stones into fine dust) and fragmentation (breaking them into small pieces for removal). About 110 children with a single stone smaller than 3 cm will be randomly assigned to one method. The main goal is to see which technique is faster overall, while also checking for safety and how well it clears the stones.

What this could mean

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

Active substance
Holmium:YAG laser
What this could lead to
If successful, this could identify the faster and safer laser technique for treating bladder stones in children, improving surgical outcomes.
What could go wrong
This is a small, early-stage trial with only 110 children. Results may not apply to larger stones or other hospitals. Both techniques are already used, so no major breakthrough is expected.
