Aquablation therapy for an enlarged prostate

How Aquablation works

As the prostate enlarges it presses on the urethra and narrows the channel urine flows through. Aquablation removes the tissue that causes the blockage.

1. You receive anesthesia, so you are asleep or numb for the procedure.
2. A camera (cystoscope) and an ultrasound probe give the surgeon live images of the prostate.
3. The surgeon maps exactly which tissue to remove and which areas to avoid.
4. A robotic handpiece directs a high-pressure waterjet to remove the mapped tissue.
5. Bleeding is controlled and a catheter is placed to drain the bladder while you heal.

Who may be a candidate

• Men with moderate to severe urinary symptoms from BPH.
• Men who have not had enough relief from medication or prefer not to take it long-term.
• Men with small, medium or large prostates, since the treatment is mapped to each prostate.

Your health, prostate size and shape and your priorities all matter. Your urologist may also discuss UroLift, prostate artery embolization, ThuLEP or TURP and HoLEP.

Before the procedure

Expect a review of your symptoms and medications, a urine test, a urine flow test, an ultrasound and often a look inside the bladder (cystoscopy). You will get instructions about blood thinners, eating and drinking, and arranging a ride home.

Recovery and possible side effects

• A catheter for a short time after surgery.
• Blood in the urine, burning and urgency are common for a few weeks as you heal.
• Avoid heavy lifting and straining until your urologist says it is fine.
• Possible risks include bleeding that needs treatment, infection, temporary trouble controlling urine and changes in ejaculation.

Call the office for heavy bleeding, clots that block urine, fever or inability to urinate.

Aquablation FAQ

What is Aquablation therapy?

Aquablation is a surgical treatment for an enlarged prostate. A robotic system uses a high-pressure waterjet, guided by live ultrasound images, to remove the prostate tissue that blocks urine flow.

Does Aquablation use heat?

No. The tissue is removed with water rather than heat. Heat may be used afterward to control bleeding.

Is there an incision?

No. The instruments are passed through the urethra, so there is no cut on the skin.

Will I need a catheter?

Yes. A catheter drains the bladder for a short time after surgery while the area heals. Your urologist will tell you when it comes out.

Will I stay in the hospital?

Aquablation is done in a hospital under anesthesia, and many men stay overnight. Your care team will explain the plan for you.

Can Aquablation affect ejaculation or erections?

Any prostate surgery can affect ejaculation. Aquablation is planned to help protect the areas linked to ejaculation and erections, but your urologist will explain the risks for your situation.
