About this study

Official title: Feasibility of Water Vaporization (Rezum®) for Patients With ≥ 30 and < 80 ml With Moderate-severe LUTS to Establish the Surgical Principles for Prominent or Non-prominent Median Lobe Enlargement: A Single-center, Prospective, Pilot Study

This study was created to determine the safety and efficacy of treating prostatic hyperplasia with or without prominent median lobe enlargement with the REZUM technique. The systematic implementation of decisions for the location, vapor time, and the number of injections contributes to the Rezum procedure configuration for the median lobe treatment being safer and standardizer.

Questions about this trial

What is this clinical trial studying?

A study testing Rezum® in people with Prostatic Hyperplasia of the Medial Lobe, run by Seoul National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 19 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

age (time frame: prior to procedure). The study lists 46 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2024.
