Study summary

Benign prostatic hyperplasia (BPH) is a common non-cancerous enlargement of the prostate gland in aging men that causes bothersome lower urinary tract symptoms (LUTS), including frequent urination, weak urinary stream, and difficulty emptying the bladder. Prostatic artery embolization (PAE) is a minimally invasive, image-guided catheter procedure that blocks blood flow to the prostate, leading to gland shrinkage and symptom relief. While traditional PAE utilizes particulate agents, N-butyl cyanoacrylate (NBCA / Histoacryl) glue is a liquid embolic material that may offer advantages such as shorter procedural duration, lower radiation exposure, and permanent vascular occlusion.

The purpose of this prospective, single-arm study is to evaluate the feasibility, safety, and clinical efficacy of using Histoacryl glue mixed with Lipiodol (1:8 dilution ratio) during prostatic artery embolization in men with symptomatic BPH who have failed or cannot tolerate medical therapy.

All enrolled participants will undergo PAE with the Histoacryl glue mixture. Participants will be monitored for procedural safety and followed up at 1 month and 3 months post-procedure. Follow-up assessments include urinary symptom improvement using the International Prostate Symptom Score (IPSS), quality of life (QoL) ratings, post-void residual urine volume, prostate-specific antigen (PSA) levels, pelvic imaging to measure prostate volume reduction, and monitoring for any procedure-related complications.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male patients aged 50 years and older.
  • Moderate or severe lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH), defined by an International Prostate Symptom Score (IPSS) of 8 or greater (moderate LUTS: IPSS 8-19; severe LUTS: IPSS 20-35).
  • Documented failure or intolerance of standard medical therapy for BPH.
  • Ability and willingness to provide voluntary written .

Exclusion criteria

Exclusion Criteria:

  • Confirmed or suspected prostate carcinoma.
  • Active urinary tract infection (UTI).
  • Renal impairment.
  • Known severe allergy or to iodinated contrast media.
  • History of prior prostatic artery embolization (PAE).
  • Refusal to participate in the study or inability to provide .
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Study arms

  • Experimental
    Prostatic Artery Embolization with Histoacryl Glue

    Participants undergo transcatheter prostatic artery embolization (PAE) using N-butyl cyanoacrylate (NBCA / Histoacryl) liquid embolic glue mixed with Lipiodol at a 1:8 dilution ratio under fluoroscopic guidance. Non-ionic glucose solution is utilized for microcatheter flushing prior to glue injection to prevent premature polymerization. Clinical, laboratory, and imaging follow-up assessments are conducted at 1 and 3 months post-procedure.

    Procedure: Prostatic Artery Embolization with N-butyl Cyanoacrylate

Interventions

  • ProcedureProstatic Artery Embolization with N-butyl Cyanoacrylate

    Participants undergo transcatheter prostatic artery embolization (PAE) performed in an angiography suite. Vascular access is secured using a 5 Fr vascular sheath and diagnostic catheter (5 Fr cobra), followed by superselective catheterization of the prostatic arteries using a 2.0-2.7 Fr microcatheter with a hydrophilic microwire. After flushing the microcatheter with a non-ionic 5% glucose solution to prevent premature polymerization, embolization is performed by injecting an N-butyl cyanoacrylate (NBCA / Histoacryl) and Lipiodol mixture at an optimized 1:8 dilution ratio under real-time fluoroscopic guidance until complete vascular stasis is achieved.

What researchers measure

Primary outcomes

  1. Clinical Success Rate

    Percentage of participants achieving clinical success, defined as a reduction in the International Prostate Symptom Score (IPSS) of at least 25% (or a minimum reduction of 3 points) from baseline without requiring additional surgical intervention or re-catheterization. The IPSS is a validated 7-item questionnaire assessing urinary symptoms, scored from 0 to 35, where higher scores represent more severe symptoms (0-7 mildly symptomatic, 8-19 moderately symptomatic, and 20-35 severely symptomatic).

    Time frame: 3 months post-procedure
