❓ What is benign prostatic hyperplasia (BPH)?
Benign prostatic hyperplasia (BPH) : also called prostate adenoma : is a non-cancerous enlargement of the prostate gland that compresses the urethra and causes urinary symptoms. It affects 2 out of 3 men over 50 and up to 90% of men over 70.
Common symptoms include: frequent urination (especially at night), weak or interrupted urine flow, urgency, difficulty starting urination, and a feeling of incomplete bladder emptying.
🔵 How does prostate artery embolization work?
PAE uses the natural pathway of the blood vessels to reach the prostate without surgery. Tiny calibrated microspheres are injected into the prostatic arteries through a catheter introduced via a small skin puncture (femoral or radial approach). The prostate gradually shrinks as its blood supply is reduced, relieving urinary symptoms.
Pre-procedure consultation : IPSS score assessment, prostate MRI, uroflowmetry, PSA
Local anaesthesia : Outpatient or 1 night hospital admission
Catheter guidance : Under X-ray fluoroscopy, the catheter is guided to the prostatic arteries
Microsphere injection : Both prostatic arteries are embolised through a single skin puncture
Same-day or next-day discharge : Progressive improvement over 1–3 months
In the international literature, prostate artery embolisation offers improvement in urinary symptoms and quality of life comparable to surgery (TURP), with far fewer complications (around 35% versus 60% for TURP) and a shorter hospital stay. Surgery remains more effective on maximum urinary flow rate and volume reduction; the choice is made on a case-by-case basis with your urologist.
