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 This study
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 Results may not be published yet.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

Summary

This study asks whether a full bladder changes the angle of the uterus in women whose uterus tilts forward. Researchers will have 30 adult women who have never given birth drink 600 mL of water, then take repeated ultrasound pictures as the bladder fills and after emptying. The goal is to see how the uterine flexion angle responds to bladder volume and what volume pushes the angle past 90 degrees. No treatment is given, and the study only observes these changes.

What this could mean

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

Active substance
Repeated pelvic ultrasound measurements of bladder volume and uterine flexion angle
What this could lead to
If bladder filling reliably shifts the uterine angle, doctors may adjust ultrasound protocols or interpret measurements with this effect in mind.
What could go wrong
This is a small observational study with no comparison group, so results may not apply to all women. Measurements depend on ultrasound technique and bladder filling patterns.

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 30 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Mar 2027
