Water vapour therapy

Urological procedure for benign prostatic hyperplasia (enlarged prostate)

Steam treatment for treating non-cancerous enlarged prostates, with fewer side-effects compared to other traditional procedures

What is water vapour therapy for the prostate?

Water vapour treatment, also known as Rezum, for benign prostatic hyperplasia (BPH) uses natural steam energy to ablate (shrink) enlarged prostate tissue. It uses a portable generator with a delivery device which is inserted into the urethra and guided to the affected prostate tissue.

The generator then heats up a reservoir of water (located outside of the body) producing steam or vapour. This is passed along the delivery device to a tiny needle with holes to ablate the targeted prostate area causing the effected tissue to shrink.

The procedure also reduces the risk of common side-effects associated with BPH treatments including erectile dysfunction, retrograde ejaculation and urinary incontinence.

What happens during water vapour therapy?

  • About the treatment icon plus

    The procedure is carried out under local or general anaesthetic, depending on your medical history.

    A generator heats up a reservoir of water, producing steam which passes through the delivery system (usually a telescope) which is inserted into your urethra. The surgeon guides this steam as it is released onto the effected prostate tissue through a tiny needle to the targeted tissue area. The affected prostate cells are destroyed, which over time will shrink naturally.

    The process takes between five and 10 minutes and is usually carried out as a day case procedure. This may differ depending on the severity of your condition. The procedure requires you to have a post-operative catheter for approximately one week.
  • How to prepare icon plus

    Your consultant will be able to provide you with exact details on how to prepare for the procedure, which is usually performed in a day case setting. As with all surgical procedures there are some risks and other side-effects involved. Your consultant will discuss these with you.
  • After treatment icon plus

    This procedure allows patients to leave hospital without an overnight stay. However, there is always a risk associated with any surgery so it is advisable to bring an overnight bag with you.

    Once your surgery is complete your consultant and nursing teams will tell you how the procedure went, the next steps and what to do when you go home. They will also advise you of any possible side effects.
     
  • Physical activity after surgery icon plus

    Where possible, we suggest someone accompanies you during your stay so they can assist your journey home. We generally advise you do not immediately commence physical activity which may compromise your surgery. For example, refrain from driving a vehicle, riding a bicycle or going for a run.
