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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two common procedures for treating upper ureteric stones: extracorporeal shock wave lithotripsy (ESWL), which uses external shock waves to break the stone, and semirigid ureteroscopy, where a thin scope is passed through the urinary tract to fragment the stone. Adults aged 18–75 with a single stone smaller than 10 mm are randomly assigned to one of the two treatments. The main goal is to see which approach achieves complete stone clearance, as confirmed by a CT scan four weeks later, while also tracking pain relief, number of sessions needed, and complications.

What this could mean

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

Active substance
Extracorporeal shock wave lithotripsy (ESWL) or semirigid ureteroscopy
What this could lead to
If one procedure proves clearly better, it could become the preferred first-line treatment for small upper ureteric stones, improving success rates and reducing repeat procedures.
What could go wrong
This is a single trial with 100 participants, so results may not apply to everyone. Both procedures carry risks like pain, bleeding, or incomplete stone clearance, and the comparison may show no meaningful difference.
