Trans-urethral needle water vapourisation of the prostate for symptomatic Benign prostatic enlargement (‘Rez̄um’)

This is a new minimally-invasive or endoscopic surgical procedure that involves using water vapour (steam) to remove obstructing prostate tissue. This improves the flow of urine from the bladder to the outside. Its unique benefits are the significantly lower risk of bleeding and sexual function side effects.

The prostate is a small gland in the pelvis only found in men. It's located between the penis and bladder and surrounds the urethra (the tube that carries urine from the bladder to the penis).

If the prostate becomes enlarged, it can place pressure on the bladder and urethra. This can cause symptoms that affect urination.



Why Rez̄um procedure is carried out

The Rez̄um procedure recommended when prostate enlargement (benign prostatic hyperplasia) causes troublesome symptoms and fails to respond to treatment with medication . It is also an option in men who wish to avoid taking long-term medication and therefore also avoiding side effects of such medication. 

We are pleased to confirm that having audited our own results of this new minimally invasive treatment, the benefits and efficacy have been confirmed and the results presented at peer reviewed local, national and international Urology conferences.

Symptoms that may improve after the Rez̄um procedure include:

  • problems starting to urinate (hesitancy)
  • a weak urine flow or stopping and starting
  • having to strain to pass urine
  • a frequent need to urinate
  • waking up frequently during the night to urinate (nocturia)
  • a sudden urge to urinate (urgency)
  • being unable to empty your bladder fully


The Rez̄um procedure is recommended when prostate enlargement (benign prostatic hyperplasia)

Key Benefits of the key benefits of the Rez̄um procedure :

  • Fast, effective and, precise BPH treatment
  • Ablates targeted tissue, which is then reabsorbed
  • Treats enlarged central zones and/or median lobes
  • Clinically proven, safe and effective
  • Reduced risk of bleeding (compared to standard Trans-urethral resection of the prostate (TURP)
  • Preserves sexual functions
  • Rapid return to normal activities


Potential Risks and Complications

As with any surgical procedure there are risks and potential complications that are associated with the Rez̄um procedure :

  • Bleeding: Risk of blood loss is minimal. The risk of bleeding requiring a blood transfusion is ≤1%
  • Infection: ≤5%. Broad-spectrum antibiotics are administered at the start of the operation to minimize the risk of a urinary infection.
  • Retrograde ejaculation: ≤2%
  • Erectile dysfunction: ≤2%.


Alternatives to the Rez̄um procedure:

  • Monopolar or Regular/Standard TURP
  • Bipolar TURP
  • Laser Prostatectomy
  • Urolift


What to Expect After Surgery

During your hospitalisation

Following your surgery, you will be transferred to the recovery room and then to your hospital room once you are fully awake.


Post-operative pain

Following surgery, pain is typically minimal and controllable with oral analgesics which will be prescribed.


Urinary Catheter

A bladder catheter is placed in the operating theatre while you are asleep and left in place for typically 3-5 days after the surgery.



Your diet will be advanced slowly from clear liquids to solid foods as tolerated once fully awake. In addition, intravenous fluids will be administered to keep your body well hydrated following surgery.



Fatigue is not uncommon and should start to subside in a few weeks following surgery.


Physical Activity

On the evening of or latest morning after surgery it is very important to get out of bed and begin walking with the supervision of your nurse or family member to help prevent blood clots from forming in your legs. During and after your hospital stay it is advised that you keep walking - The more walking you can tolerate the better.


Hospital Stay

The Rez̄um procedure is a day-case procedure – patients are discharged home with a catheter the same day.
