Rezum is a procedure that helps men whose lives are bothered by urinary symptoms return to live their life more normally with no or minimal impact on erections or ejaculation. It is also called water-vapour ablation of the prostate.

How does Rezum work?

Steam is injected into the enlarged part of the prostate which then shrinks over 2 to 12 weeks.

To do this, a urologist passes a very narrow telescope though the urethra, which is the channel that carries urine from the bladder to the penis. The urologist looks at the inside of the prostate to see which parts seem to block the flow of urine. Then, he or she injects steam into those areas. The procedure is done usually under a short general anaesthetic or sedation. There can be some temporary swelling after, so a catheter is needed for several days. The catheter is removed later.


What are the advantages of Rezum?
  • Severe urinary symptoms become mild or mild-moderate and no longer interfere in daily life
  • Erections and ejaculation are usually the same after Rezum as they were before
  • The procedure is a day case and you do not need to stay overnight
  • There is almost no bleeding in most cases
  • As a very narrow telescope is used, there is little chance of damaging the urethra
  • You can still have other procedures for the prostate after if you want
Who is suitable for Rezum?
  • Men who have bothersome urinary symptoms due to the prostate
  • Men who have a new lobe of the prostate called a median lobe
  • Men who don’t want to take pills to improve their symptoms
  • Men whose prostates are between 30 and 80 cc in size
How long does it take to recover from a Rezum?

Men go home the same day with a catheter. Between two and seven days later, the catheter is removed. Urinary symptoms take two to 12 weeks to improve. Normal work can be resumed usually within a week or two.
