PAE or Aquablation:
the honest comparison
These are the two BPH treatments with no practical size limit, and the two most men with large prostates end up choosing between. Dr. Sawkar performs both, prostate artery embolization in the practice's own lab and Aquablation at the hospital, more than 250 cases in, so this comparison has no thumb on the scale.

Side by side
Two different philosophies: PAE starves the excess tissue so the gland shrinks; Aquablation removes it outright with a robotic waterjet. Both preserve sexual function far better than traditional surgery.
| PAE | Aquablation | |
|---|---|---|
| How it works | Microspheres reduce the prostate's blood supply; the gland shrinks over weeks | A heat-free robotic waterjet removes obstructing tissue in one session |
| Setting | Outpatient lab, home the same day | Hospital, usually one night |
| Anesthesia | Light sedation | Spinal or general |
| Catheter | Usually none | One to two days |
| Back to routine | About a day | One to two weeks |
| Prostate size range | No practical ceiling, 200+ cc treated | Proven 30 to 150 cc |
| Blood thinners | Usually continued | Usually paused around surgery |
| Result timeline | Builds over 4 to 12 weeks | Evident once the catheter is out |
| Durability | Strong; roughly 1 in 5 seek retreatment over years | Most definitive of the minimally invasive options |
General patterns, not a promise. Your measured anatomy, health, and goals decide, which is exactly what the consultation is for.
How men actually choose
Choose PAE when disruption is the enemy
You want to keep working, keep your blood thinners, skip the hospital, and let relief build over weeks. PAE asks almost nothing of your calendar, and it closes no doors if you ever want more later.
Choose Aquablation when you want it settled
You want the most definitive single treatment, measured in decades of tissue simply being gone, and a night in the hospital is an acceptable price. The robot protects function while the obstruction is removed outright.
Let the measurement referee
Gland size, shape, median lobe, bladder health, and your medical history all weigh in. A quick ultrasound turns this page's generalities into your specific answer.
Common questions
Which is more effective, PAE or Aquablation
Aquablation removes tissue, so its symptom relief is somewhat stronger and more durable on average. PAE shrinks the gland without surgery, with lighter recovery and no hospital stay, at the cost of a somewhat higher chance of wanting retreatment years later. Which trade is right depends on your anatomy, health, and priorities.
Which has the easier recovery
PAE, clearly. It is outpatient with light sedation, usually no catheter, and most men are back at a desk in a day or two. Aquablation involves a night in the hospital, a catheter for a day or two, and about a week before routine feels normal.
Can I have PAE first and Aquablation later
Yes. PAE removes no tissue and closes no doors, so Aquablation remains fully available afterward if you ever need more. Starting with the gentler option is a legitimate strategy for many men.
Who should choose Aquablation over PAE
Men who want the most definitive one-time result, have anatomy suited to surgical resection, and are comfortable with a hospital stay. Men prioritizing minimal disruption, avoiding general anesthesia, or staying on blood thinners usually look at PAE first. A measured prostate and a candid conversation settle it.
