Complete Guide to PAE for BPH in Van Nuys

Prostate artery embolization (PAE) is one of several treatment options for bothersome urinary symptoms attributed to benign prostatic hyperplasia (BPH). It is performed by an interventional radiologist through a small arterial access site rather than through the urethra.

For patients considering PAE in Van Nuys, the most important questions are whether BPH is truly causing the symptoms, whether the arterial anatomy is suitable, and how PAE compares with medication or surgery for the individual patient.

What PAE is intended to treat

PAE is intended for selected patients with lower urinary tract symptoms related to benign prostate enlargement. Common symptoms include a weak or interrupted stream, difficulty starting, urgency, frequency, nighttime urination, straining, and incomplete emptying. These symptoms can have other causes, so an enlarged prostate on imaging is not enough by itself to choose treatment.

Patients who cannot urinate, have recurrent infection, bladder stones, kidney effects, significant bleeding, or another complication may need expedited urologic evaluation. Prostate cancer evaluation should be addressed when clinically appropriate.

Evaluation before PAE

A PAE evaluation may include medical and medication history, a standardized symptom score, urinalysis, prostate-specific antigen testing when appropriate, prostate imaging, and measurement of urinary flow or urine remaining after voiding. Additional testing such as cystoscopy or urodynamics may be useful when the cause of symptoms is unclear.

Interventional-radiology review also considers kidney function, contrast allergy, vascular disease, anticoagulants, prior pelvic treatment, prostate anatomy, and the arteries supplying the prostate. Some patients benefit from coordinated urologic and interventional-radiology opinions before choosing an option.

How the procedure is performed

1. A small arterial access site is created, commonly at the wrist or groin.
2. Using x-ray guidance, the physician advances a catheter into pelvic arteries.
3. Selective angiography identifies prostate branches and nearby vessels.
4. Microscopic particles are delivered to reduce blood flow to targeted prostate tissue.
5. The catheter is removed and the access site is monitored.

The procedure is technically demanding because pelvic arterial anatomy varies. The goal is to treat prostate branches while avoiding vessels that supply the bladder, rectum, penis, skin, or other structures.

What the evidence shows

Randomized trials and cohort studies show that PAE can improve symptoms and quality of life in selected patients. A randomized sham-controlled trial supported a treatment effect beyond a sham procedure. Comparative evidence also shows important tradeoffs.

In a five-year randomized trial comparing PAE with TURP, symptoms improved after both procedures, but TURP produced greater improvement in several patient-reported and objective urinary outcomes. Patients should understand that PAE’s less invasive access does not mean it will deliver the strongest improvement for every prostate or bladder.

Potential benefits and limitations

Potential advantages include treatment through a small puncture, avoidance of transurethral tissue removal, and outpatient care in many cases. PAE may be attractive to selected patients who want to avoid or are not ideal candidates for a transurethral operation.

Limitations include variable symptom response, gradual rather than immediate improvement, technical failure or incomplete embolization, and the possibility of continued medication, repeat embolization, or later surgery. Urinary-flow improvement may be less pronounced than after tissue-removing procedures.

Risks

Potential risks include access-site bruising or bleeding, temporary pelvic pain or urinary irritation, blood in the urine or semen, acute urinary retention, infection, contrast reaction, kidney injury, radiation exposure, and rare non-target embolization that can injure nearby tissue. Erectile or ejaculatory function is often preserved, but no sexual outcome can be promised.

Recovery and follow-up

Discharge timing, activity restrictions, and medication instructions depend on the access site, sedation, medical history, and how the procedure proceeds. Temporary urinary frequency, burning, pelvic discomfort, fatigue, constipation, or a short-term symptom flare may occur. Improvement, when it occurs, is generally assessed over weeks to months.

Patients should follow the treating team’s instructions and report fever, inability to urinate, worsening pain, heavy bleeding, access-site swelling, skin changes, or other concerning symptoms. Read the detailed PAE recovery guide.

Questions to resolve before choosing PAE

• What evidence shows that BPH is causing my symptoms?
• What are my prostate size, postvoid residual, and urinary-flow findings?
• What result is realistic for me, and how quickly might it occur?
• How do PAE, TURP, HoLEP, medication, and other options compare for my anatomy?
• What risks are increased by my kidney function, arteries, medicines, or other conditions?
• What follow-up and possible retreatment should I expect?
