Rezum water vapour therapy is a minimally invasive surgical treatment for benign (noncancerous) enlargement of the prostate gland. The treatment involves the delivery of small amount of water steam into your prostate. During this treatment, a cystoscope (small tube) will be inserted into your urethra. This contains a small needle that will deliver the water vapour. The hot steam causes the prostate cells to die.

​

The treatment takes about one hour and patients are usually able to go home the same day.

​

Any discomfort is usually treated with simple pain killers which may be given as required before, during or after the procedure.

​

Over a few weeks the enlarged part of the prostate shrinks in size which improves the flow of pee when the bladder is emptying. All patients undergoing this procedure will need a catheter for around 7 days afterwards.
