High-Frequency Irreversible Electroporation vs Standard of Care for Benign Prostatic Hyperplasia

Plain-language summary

The study aims to find a better surgical treatment for men with an enlarged prostate (Benign Prostatic Hyperplasia, or BPH) that effectively relieves urinary symptoms without sacrificing sexual function. Currently, standard surgeries like TURP or HoLEP are very effective at opening the blocked urinary channel. However, because they use heat or mechanical energy to remove prostate tissue, they often cause unwanted side effects, most notably the loss of normal ejaculation (retrograde ejaculation) and potential impacts on erectile function. This study is testing a novel, minimally invasive technology called High-Frequency Irreversible Electroporation (H-FIRE). Instead of using heat to burn or cut the tissue, H-FIRE delivers ultra-short electrical pulses to destroy the blocking prostate tissue. This "non-thermal" (heat-free) approach is uniquely designed to spare the delicate nerves, blood vessels, and muscles surrounding the prostate, which are critical for preserving normal sexual function and bladder control. In this clinical trial, 288 men aged 50 and older with moderate-to-severe BPH symptoms will be randomly assigned to receive either the investigational H-FIRE procedure or the Standard of Care surgery (TURP or HoLEP). The main goal of the study is to prove that H-FIRE is just as effective as standard surgery in relieving lower urinary tract symptoms over 12 months. More importantly, the study will evaluate if H-FIRE is superior in helping patients achieve the "BPH Trifecta"-meaning the patient successfully achieves significant symptom relief, maintains perfect bladder control (uses zero pads), AND fully preserves normal ejaculation. By utilizing this new tissue-sparing technology, the trial hopes to offer aging men a treatment option that restores their urinary health while fully protecting their overall quality of life.
