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 Results may not be published yet.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
The full record has not been published yet, so there is little to show here.

Summary

This study tests a new training tool for kidney stone surgery. Trainee surgeons wear augmented reality goggles that show them where an expert surgeon is looking during the operation. The goal is to help trainees learn to explore the kidney more completely, which could reduce the chance of leftover stone fragments that cause repeat surgeries. The study will enroll 110 participants, including surgeons and patients, at Vanderbilt University Medical Center.

What this could mean

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

Active substance
Augmented reality device (Microsoft HoloLens 2) that displays an expert surgeon's eye gaze to a trainee during surgery
What this could lead to
If it works, this could lead to better surgical training tools that help novice surgeons learn faster and reduce the need for repeat kidney stone surgeries.
What could go wrong
This is a small, early-stage study focused on training, not a treatment. The device may not improve skill or patient outcomes, and it could be distracting or impractical in the operating room.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 110 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jan 2025

Expected to finish

Aug 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Surgeons who are "adult" residents and attending urologists at Vanderbilt University Medical Center in the age range 18 to 65 * Patients who are adults with kidney stones scheduled for endoscopic surgery as clinically indicated. Exclusion Criteria: * Vulnerable populations, including incarceration status, pregnancy, inability to give informed consent, and serious illness likely to cause death within 5 years
