Convective Radio-frequency Water Vapor Energy Verses Trans-urethral Enucleation of Prostate for Management of Benign Prostatic Hyperplasia

May 15, 2026 updated by: Hany Fathy Badawy, MD, Beni-Suef University

Prospective Study Comparing Convective Radio-frequency Water Vapor Energy With Trans-urethral Enucleation of Prostate for Management of Benign Prostatic Hyperplasia

Convective RF water vapor energy was introduced as a minimally invasive, radio-frequency thermal energy-based treatment, designed to convectively deliver sterile water vapor, or steam for targeted ablation limited to the transition and central zones in men with clinical BPH. Thus. the aim of the study is to compare Convective RF water vapor energy (Rezum) with trans-urethral enucleation of the prostate (TUEP) regarding efficacy in terms of lower urinary tract symptoms (LUTS) improvement, international prostatic symptoms score (IPSS), improving of the maximum flow rate (Qmax), worsening of erectile and ejaculatory function, and safety regarding post operative complications & hospital stay.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
International Prostate Symptom Score (IPSS)
Time Frame: 1, 6, 12 months
The total score ranges from 0 to 35, where 0 indicates no symptoms and 35 indicates the most severe symptoms. Higher scores represent worse urinary symptoms and poorer clinical status.
1, 6, 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
International Index of Erectile Function (IIEF-EF)
Time Frame: 1, 6, 12 months
The erectile function domain score ranges from 1 to 30, where lower scores indicate more severe erectile dysfunction and higher scores indicate better erectile function. Higher scores represent better clinical outcomes.
1, 6, 12 months
four-item version of Male Sexual Health Questionnaire (MSHQ-EjD Short Form)
Time Frame: 1, 6, 12 months
The total score ranges from 1 to 15 for the ejaculatory function domain, with higher scores indicating better ejaculatory function. In the bother item, scores range from 0 to 5, where higher scores indicate greater bother or distress related to ejaculatory dysfunction.
1, 6, 12 months
Qmax maximum urinary flow rate
Time Frame: 1, 6, 12 months
Maximum urinary flow rate (Qmax) will be assessed using uroflowmetry, a non-invasive urodynamic test that measures the maximum flow rate of urine during voiding. Qmax is reported in milliliters per second (mL/s). Higher values indicate better urinary flow and improved urinary function.
1, 6, 12 months
Post Void Residual volume (PVR)
Time Frame: 1, 6, 12 months
Post-Void Residual urine volume (PVR) will be assessed using bladder ultrasound immediately after voiding to determine the amount of urine remaining in the bladder. PVR is reported in milliliters (mL). Higher values indicate worse bladder emptying and poorer urinary function.
1, 6, 12 months
