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.

What is the study measuring?

Primary Outcome Measures

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

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
