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 Results may not be published yet.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 trial asks whether routinely identifying and freeing the ureters before cutting uterine vessels during laparoscopic hysterectomy reduces the chance of ureter injury compared with doing so only when specific problems arise. It will include thousands of women having the surgery for benign conditions. The main measure is how often ureter injuries occur within 90 days after surgery, with other outcomes like operative time and complications also tracked.

What this could mean

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

Active substance
Routine bilateral ureterolysis (a surgical step to identify and protect the ureters) compared with selective ureterolysis performed only when specific safety concerns arise.
What this could lead to
If routine ureterolysis proves better, it could become the standard approach in laparoscopic hysterectomies, potentially reducing the risk of ureter injury and improving patient safety.
What could go wrong
The trial is large but the outcome depends on surgical skill and patient variability; routine dissection might increase operative time or bleeding without reducing injury risk.

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 35,000 people

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

Expected to start
