Rezum Therapy

Rezum is a minimally invasive procedure that uses the natural energy stored in a few drops of water to treat benign prostatic hyperplasia (BPH).

What is BPH?

Benign prostatic hyperplasia (BPH) is an enlargement of the prostate gland. This enlargement can compress the urethra, reducing the flow of urine from the bladder and sometimes blocking it entirely.

Lower urinary tract symptoms are common in older men with benign prostatic hyperplasia (BPH). Among men between the ages of 50 and 60, the incidence increases to 90% by the age of 80.

Symptoms of BPH


Urinary frequency

Irregular flow

Weak stream


Getting up at night to urinate sometimes with a feeling of incomplete emptying.

Minimally invasive treatments

Traditionally treatment options include making lifestyle changes for mild symptoms as well as medication prior to surgery.

A minimally invasive treatment intervention for men with moderate symptoms is Rezum Steam Therapy also known as Rezum Water Therapy.

How is Rezum performed?

Rezum Therapy is usually performed as a day case procedure under local anaesthesia and sedation.

A controlled amount of water is converted into steam or vapour and delivered into the prostate tissue which causes BPH. The vapour ablates (removes) the obstructive prostate tissue.

As saline is delivered through the device, visualisation is enabled, and the urethra is kept cool to prevent thermal damage from the vapour.

Throughout the treatment saline (salty water) is running to ensure the urethra is kept cool and a clear view is maintained.

Is Rezum Therapy right for me?

Talk to your experienced consultant urologist to determine whether Rezum is right for you based on your symptoms and treatment goals.

The advantage of this treatment over bigger operations such as the TURP procedure is that it has a very favorable side effect profile and is quick to perform. It is a safe procedure where symptomatic improvement is predictable and is a safe procedure.

Typically, men aged 50 to 75, looking for symptomatic improvement and looking to maintain sexual function.

Even though the procedure just takes a few minutes, depending on the anaesthesia used, you may need to stay in hospital for a while before and after. You are very likely to be discharged on the same day.

You will be given some strong painkillers and antibiotics to take an hour prior to the therapy. The procedure will subsequently be performed in the theatre, where you will be accompanied. If a general anaesthetic is being used, you will be put to sleep. For this procedure, most men will be awake.

A local anesthetic will then be administered around the prostate gland with the use of an ultrasound probe via the back passage. This may feel a bit uncomfortable, but the more relaxed you are the easier it will be.

The Rezum technology is passed through the urethra using plenty of anaesthetic gel. After a quick inspection of the bladder, the treatment will begin.

After your procedure, you will be reviewed by a member of the urology team who will discuss the operation, any specific requirements for you at home, and a plan for your aftercare.

A date will be given to you as to when to return for the catheter removal as well as the care required whilst at home.

Some pain or discomfort is normal after operations. Painkillers will help to keep it under control.

You will be able to return to normal activities within a few days and should notice improvements within 2 weeks although it may be 3 months before the full benefit is evident. You may notice blood in your urine and ejaculation fluid for a couple of days while your urethra heals. We recommend you avoid ejaculation for 6-8 weeks.
