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 Results may not be published yet.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

Summary

This study tracks 1,400 men with an enlarged prostate who receive Rezūm, a procedure that uses steam to shrink excess tissue. Researchers aim to identify which patients are most likely to have lasting symptom relief, avoid repeat treatments, and preserve sexual function. The goal is to develop clearer guidelines for who benefits most from this minimally invasive option.

What this could mean

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

Active substance
Rezūm therapy (convective water vapor thermal ablation using steam)
What this could lead to
If successful, this study could help doctors better predict which men will benefit most from steam therapy for an enlarged prostate and reduce the need for repeat treatments.
What could go wrong
This is an observational registry, not a controlled trial, so results may not prove cause and effect. Some men may still experience temporary urinary retention or need additional treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Participants

About 1,400 people

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

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Sep 2027

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.
