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.
