Prostate Artery Embolization (PAE) is a minimally invasive, image-guided procedure used to treat benign prostatic hyperplasia (BPH)—a non-cancerous enlargement of the prostate gland. BPH is a common condition in aging men and can cause urinary symptoms such as frequent urination, weak urine stream, or difficulty starting urination.
During the PAE procedure, an interventional radiologist inserts a catheter through a small incision, usually in the groin or wrist, and navigates to the arteries supplying the prostate. Tiny particles are then injected to block blood flow to specific areas of the prostate. This reduction in blood flow causes the prostate to shrink over time, relieving pressure on the urethra and improving urinary symptoms.
Benefits of PAE
- Minimally invasive: No surgical incision into the prostate
- Performed under local anesthesia with mild sedation
- Shorter recovery time compared to traditional surgery
- Lower risk of sexual side effects such as erectile dysfunction or retrograde ejaculation
- Can be a treatment option for men who are not candidates for surgery
Ideal Candidates
PAE is generally recommended for men with moderate to severe BPH symptoms who:
- Prefer a non-surgical treatment option
- Have not responded well to medications
- Wish to preserve sexual function
- Are considered high-risk for traditional surgery
Recovery and Results
Most patients return home the same day and resume normal activities within a few days. Symptom relief typically begins within a few weeks and continues to improve over several months. Clinical studies have shown significant long-term improvement in urinary symptoms and quality of life following PAE.
