Prostate Artery Embolization (PAE): Frequently Asked Questions

Prostate Artery Embolization is a minimally invasive, image-guided procedure that shrinks an enlarged prostate by reducing its blood supply. An interventional radiologist threads a thin catheter through a small puncture in the wrist or groin, guides it to the arteries feeding the prostate, and releases tiny embolic particles that block blood flow to the gland. Over the following weeks and months, the prostate gradually shrinks, relieving pressure on the urethra and easing urinary symptoms. According to Johns Hopkins Medicine, PAE is performed entirely through the vascular system, meaning there are no surgical incisions involved.

During PAE, you’ll typically receive moderate sedation rather than general anesthesia. The interventional radiologist inserts a catheter into an artery, injects contrast dye to map the blood vessels supplying the prostate, and then delivers microscopic particles that lodge in those vessels. The entire procedure generally takes between 90 minutes and a few hours, and most patients go home the same day. Because there’s no incision to heal and no hospital stay required, recovery is significantly faster than with traditional prostate surgery.

Candidacy for PAE depends on several factors that your care team will evaluate during a consultation. Good candidates typically have moderate to severe urinary symptoms from BPH, a prostate that hasn’t responded well to medication, and anatomy suitable for catheter-based treatment. Before any treatment decision is made, it’s essential to rule out prostate cancer, since PAE is designed specifically to treat benign prostate enlargement, not cancer. You can learn more about how BPH is diagnosed and what distinguishes it from prostate cancer on our About BPH page.

Certain conditions may make PAE less suitable, including:

• Urinary symptoms caused by something other than prostate enlargement, such as urethral stricture

• Confirmed or suspected prostate cancer that hasn’t been ruled out

• Active urinary tract infection or prostatitis (often a temporary, treatable barrier)

• Significant kidney impairment, given the contrast dye used during imaging

• Severe atherosclerosis or vascular anatomy that makes catheter access difficult

• A severe allergy to iodinated contrast media

Every patient’s anatomy and health history are different, which is why a personalized evaluation with an experienced interventional radiology team matters more than any single rule of thumb.

Most men experience only mild discomfort at the catheter insertion site, along with possible bruising. Because general anesthesia isn’t used, recovery tends to be quicker than with surgical alternatives. That said, some patients experience what’s known as “post-embolization syndrome” in the days following treatment — a temporary cluster of symptoms that can include mild fever, nausea, or pelvic discomfort, as noted by Johns Hopkins Medicine. Most men return to normal daily activities within a few days, while noticeable urinary symptom improvement often continues over the following weeks to months as the prostate gradually shrinks.

One of the most common concerns men raise is whether treatment will affect erections or ejaculation. This is an area where PAE differs meaningfully from surgical options. Research published in the Journal of Vascular and Interventional Radiology found that PAE was associated with improved erectile function scores in a majority of patients studied, with no reported cases of new ejaculatory dysfunction. Because the procedure targets only the arteries supplying the prostate rather than the surrounding nerves, it carries a meaningfully lower risk of the sexual side effects associated with more invasive surgical procedures like TURP. As with any medical treatment, individual outcomes vary, so it’s worth discussing your specific risk factors during your consultation.

Clinical studies report meaningful, lasting symptom relief for the majority of patients following PAE. A large single-center analysis published in the Journal of Vascular and Interventional Radiology tracking over 1,000 patients found that most men remained free of the need for further intervention for years after treatment. Recognizing this growing body of evidence, the American Urological Association updated its official BPH management guideline in 2023 to formally include PAE as a treatment option for appropriately selected patients — a significant shift from earlier guidance.

It’s worth understanding that, like other BPH treatments, PAE isn’t necessarily a one-time, permanent fix for every patient. Because the prostate tissue is still present (just with reduced blood supply), some men may eventually need a follow-up procedure years down the road, particularly if only one side of the prostate was embolized rather than both. This is a conversation worth having candidly with your interventional radiologist so you understand the full picture of expected durability, not just the initial success rate.

Transurethral resection of the prostate (TURP) has long been considered a surgical gold standard for BPH, and it typically offers a lower chance of needing a repeat procedure. However, TURP requires general or spinal anesthesia, often involves a hospital stay, and carries a meaningfully higher risk of sexual side effects, including retrograde ejaculation. PAE trades some of that long-term durability for a substantially easier recovery, outpatient convenience, and a lower risk profile for sexual function. If your care team determines that surgery may be a better fit for your specific anatomy or symptom severity, our in-house urology care team can walk you through those options as well, so you’re choosing the treatment path that’s right for you — not just the one a single specialist happens to offer.

Coverage for PAE varies by payer and plan. According to the Centers for Medicare & Medicaid Services, Medicare Part B generally covers medically necessary embolization procedures performed on an outpatient basis, subject to the annual Part B deductible and standard 20% coinsurance. Many commercial insurance plans also cover PAE, though coverage policies differ by insurer and sometimes require prior authorization. Our team can help verify your specific benefits before your procedure. Visit our Accepted Insurance page for a full list of the plans we currently work with, or reach out to our billing team with questions about your coverage.

Your first visit typically includes a review of your symptoms and medical history, a discussion of how long you’ve been experiencing urinary issues, and diagnostic testing such as a PSA blood test and imaging to assess your prostate’s size and anatomy. This evaluation helps your care team confirm that BPH — not another condition — is the cause of your symptoms, and helps determine whether PAE, medication, or another approach is the most appropriate next step for you.
