About this study

Official title: Prospective, Non-Randomized, Controlled Investigation of Prostate Artery Embolization Compared to Holmium Laser Enucleation of Prostate for the Treatment of Symptomatic Benign Prostatic Hyperplasia in Prostate Glands Larger Than 80 Grams

The purpose of this research study is to evaluate prostate artery embolization (PAE) compared to Holmium laser enucleation of prostate (HoLEP) in improving a patient's overall prostate related symptoms.

Being tested
Embosphere Microspheres, HoLEP Procedure
Medical subject headings
Prostatic Hyperplasia

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Embosphere MicrospheresDevice

    The SOC PAE procedure will be performed by attempting to embolize prostatic arteries of both sides in a single session with 300-500 um Embosphere Microspheres. The microspheres will be mixed with a contrast agent and will be delivered to the arteries supplying the prostate via a microcatheter.

  • HoLEP ProcedureProcedure or surgery

    The SOC PAE procedure will be performed with the SOC HoLEP as per standard institutional guidelines. The HoLEP procedure involves passing a telescope through the urethra and removing the central part of the prostate gland using a laser.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in BPH symptoms as measured by the IPSS

    The International Prostate Symptom Score (IPSS) has a total score ranging from 0-35 with the higher score indicating more severe symptoms

    Measured: Baseline, 3 months

Secondary outcomes (13)
  1. Duration of hospitalization after the procedure

    The duration of hospitalization associated with each procedure will be calculated in hours.

    Measured: up to 48 hours

  2. Duration of urinary catheterization after the procedure

    The duration of urinary catheterization associated with each procedure will be calculated in hours.

    Measured: up to 48 hours

  3. Change in BPH symptoms as measured by IPSS

    International Prostate Symptom Score (IPSS) has a total score ranging from 0-35 with the higher score indicating more severe symptoms

    Measured: Baseline, 12 months

  4. Change in peak urine flow rate

    The peak urine flow rate (Qmax) will be measured via uroflowmetry

    Measured: Baseline, 12 months

  5. Change in post-void residual urinary volume (PVR)

    PVR will be measured using an ultrasound bladder scanner

    Measured: Baseline, 12 months

  6. Change in erectile function as measured by the IIEF

    The International Index of Erectile Function (IIEF) has a total score ranging from 0-25 with higher score indicating better erectile function

    Measured: Baseline, 12 Months

  7. Change in retrograde ejaculation as measured by the Ejaculatory questionnaire

    The Ejaculatory Questionnaire has a total score ranging from 0-20 with the higher score indicating better outcomes

    Measured: Baseline, 12 Months

  8. Change in incontinence as measured by the ICIQ - UI SF

    The International Consultation on Incontinence Questionnaire (ICIQ) -Urinary Incontinence (UI) Short Form (SF) is a 4-item self-report of urinary incontinence to document changes in bladder function. Scores range from 0-21, with greater values indicating increased severity.

    Measured: Baseline, 12 Months

  9. Change in mean prostate volume

    As measured by Magnetic Resonance Imaging (MRI) and transrectal ultrasound (TRUS)

    Measured: Baseline, 12 months

  10. Change in prostate specific antigen (PSA) levels

    As measured by serum blood samples

    Measured: Baseline, 12 Months

  11. Incidence of adverse events

    As evaluated by treating physician

    Measured: Up to 12 Months

  12. Incidence of procedure-related adverse events

    As evaluated by treating physician

    Measured: Up to 12 Months

  13. Change in medication use related to BPH-LUTS

    Change in BPH lower urinary tract symptoms (LUTS) medication use (including alpha blockers, 5-alpha reductase inhibitors and phosphodiesterase type 5 (PDE5) inhibitors) will be reported

    Measured: Baseline, 12 Months

Questions about this trial

What is this clinical trial studying?

A study testing Embosphere Microspheres and HoLEP Procedure in people with Benign Prostatic Hyperplasia, run by University of Miami at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 20 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in BPH symptoms as measured by the IPSS (time frame: Baseline, 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2026.
