PAE reduces prostate volume through its arterial supply and can improve urinary symptoms without transurethral surgery.
Benign prostatic hyperplasia (BPH) affects most men as they age. The growing gland squeezes the urethra, causing weak stream, difficulty starting, dribbling, urgency, incomplete emptying and waking repeatedly at night. Medication helps many men, but some experience side effects such as dizziness, fatigue or sexual dysfunction. Traditional surgery (such as TURP) works well but involves an operation through the urethra, a hospital stay, and a high rate of retrograde ejaculation.
PAE approaches the prostate from the inside of its blood vessels rather than through the urethra. Via a pinhole in the wrist or groin, a microcatheter is steered into the small arteries supplying the prostate, and microscopic particles are injected to reduce its blood supply. Over the following weeks the gland shrinks and softens, the pressure on the urethra eases, and urinary symptoms improve.
Review of your symptoms, flow studies and PSA, with CT or MRI to map the prostatic arteries and plan the procedure.
Performed under sedation through a single pinhole. Both prostatic arteries are treated. No instruments pass through the urethra and there is no cutting.
Most men walk out a few hours after the procedure. Mild burning with urination or pelvic discomfort for a few days is common and settles with simple measures.
Symptoms typically improve progressively over two weeks to three months as the gland shrinks. Follow-up confirms your progress.
The large majority of men experience meaningful, durable improvement in urinary symptoms and quality of life after PAE, and it is now supported by international guidelines as an option for selected men. Ejaculatory function is preserved in many patients, which is an important reason some men choose PAE.
Expected after-effects include a few days of urinary frequency or burning and mild pelvic discomfort. Uncommon risks include temporary urinary retention, blood in the urine or semen, and rarely non-target embolisation. Some men have a partial response or need further treatment in later years; if so, all surgical options remain open.
TURP remains a very effective operation and for some men it's the right choice. PAE can provide substantial symptom relief for selected men, without urethral instrumentation and often with same-day discharge, and may better preserve sexual function. The trade-off is a somewhat higher chance of needing repeat treatment in future years.
PAE preserves ejaculatory function in many men, and erectile function is usually unaffected. This is the key difference from TURP, where retrograde ejaculation is very common.
Often, yes. PAE has good published success at restoring spontaneous urination in men with retention, and it's a particularly good option for men who are poor surgical candidates.
Some men improve within a fortnight; for most the full benefit develops over one to three months as the prostate shrinks.
