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
The trial has finished. Results may not be published yet.
Stopped early This study
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 tests whether a massage percussion device can help people pass tiny kidney stone fragments left behind after a common stone-removal surgery. After surgery, small fragments often remain in the kidney and may not pass on their own, sometimes requiring another procedure. Participants will use the massage device on their back or side to see if it helps move the fragments out. The trial focuses on whether people can tolerate the therapy and whether it improves the rate of becoming stone-free.

What this could mean

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

Active substance
Massage Percussion Therapy device
What this could lead to
If effective, this could offer a simple, non-invasive way to help people pass leftover kidney stone fragments after surgery, reducing the need for additional procedures.
What could go wrong
This is a very small, early feasibility study with only 13 participants. The therapy may not improve stone passage and could cause discomfort or be poorly tolerated.
