BackgroundBenign prostatic hyperplasia BPH is a prevalent entity in elderly men and transurethral resection of the prostate TURP still represents the gold standard of surgical treatment despite its considerable perioperative morbidity. Recently, prostatic artery embolization PAE was described as a novel effective and less invasive treatment alternative. Despite promising first results, PAE still has to be considered experimental due to a lack of good quality studies. Prospective randomized controlled trials comparing PAE with TUR-P are highly warranted.

Methods-designThis is a single-centre, prospective, randomized, non-inferiority trial comparing treatment effects and adverse events of PAE and TURP in a tertiary referral centre. One hundred patients who are electable for both treatment options are randomized to either PAE or TURP. Changes of the International Prostate Symptom Score IPSS after 3 months are defined as primary endpoint. Changes in bladder diaries, laboratory analyses, urodynamic investigations and standardised questionnaires are assessed as secondary outcome measures. In addition contrast-enhanced magnetic resonance imaging of the pelvis before and after the interventions will provide crucial information regarding morphological changes and vascularisation of the prostate. Adverse events will be assessed on every follow-up visit in both treatment arms according to the National Cancer Institute Common Terminology Criteria for Adverse events and the Clavien classification.

DiscussionThe aim of this study is to assess whether PAE represents a valid treatment alternative to TURP in patients suffering from BPH in terms of efficacy and safety.

Trial NCT02054013.
