Run by Oslo University Hospital · NCT04084938 · Data updated 2026-11-12

This study is testing whether a new procedure called prostate artery embolization works as well as traditional surgery for men with an enlarged prostate and bothersome urinary symptoms.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are men with moderate to severe LUTS due to BPH, refractory to medical treatment, and willing to undergo both PAE and surgery.

Probably not a fit

Patients with clinically significant prostate cancer, severe renal insufficiency, or previous prostate surgery may not benefit from this study.

What this trial studies

This study aims to compare prostate artery embolization (PAE) with traditional surgical treatment for benign prostatic hyperplasia (BPH) in terms of patient acceptance, complications, and functional outcomes. A total of 140 patients suffering from lower urinary tract symptoms (LUTS) will be randomized to receive either PAE or surgery. Prior to randomization, patients will undergo imaging to ensure eligibility, and both procedures will be performed in specialized departments. Follow-up assessments will be conducted at 3 months, 1 year, and 5 years to evaluate recovery and complications.

Why it matters

Potential benefit: If successful, this study could provide a less invasive treatment option for patients with benign prostatic hyperplasia, potentially reducing recovery time and complications.

How similar studies have gone: While PAE has shown promise in preliminary studies, it has not yet been widely adopted into clinical guidelines, making this approach relatively novel.
