The Rezum Procedure

The Rezum Procedure for Benign Prostatic Hyperplasia (BPH) is a cutting-edge procedure for treating BPH in men, using water vapor ablation.


How does Rezum work?

During the Rezum procedure, water vapor or steam is directed at the enlarged prostate gland resulting in the removal of extra prostate tissue.

Why would Rezum be performed?

The procedure is performed for the following reasons:

  • To address chronic issues of urine flow obstruction
  • To decrease or treat urination problems that include low urine output, difficulty passing urine or the inability to urinate, frequent night-time urination, and ‘dripping’ that may occur at the completion of the urination process.
  • When medications and other surgical procedures for treating BPH have not resulted in an improvement or cure

How is the Rezum Procedure Performed?

Rezum therapy is performed in the following manner:

  • Your urologist directs tiny streams of water vapor (steam) via the urethra to the targeted region of enlarged prostate gland causing the symptoms
  • Using the stored energy within steam, excess cells are destroyed and extra tissues are slowly removed from the prostate by the body
  • This results in an overall decrease to the size of the prostate gland.

Where is the Procedure Performed?

Rezum therapy is a minimally invasive procedure, it can be performed in a doctor’s office, clinic or other outpatient setting.

How long will the Procedure take?

The time taken to complete the procedure ranges from 15-30 minutes. However, the actual procedure itself may only take around 3-5 minutes to complete.

What should I inform my urologist about, prior to the procedure?

It is important to inform your urologist about the following:

  • please provide a list of all medications you are currently taking
  • if you are allergic to any specific foods or medicines
  • if you are taking anticoagulants (blood thinners) such as aspirin, warfarin, or herbal supplements (some herbal substances can act as blood thinners)
  • if you or your family members have a history of bleeding disorders, or a tendency to bleed more than normal
  • a history of diabetes, high blood pressure, chest pains, or myocardial infarction (heart attack)
  • a history of deep vein thrombosis (blood clots in the legs) or lung emboli (blood clots in the lungs)
  • a list of all previous surgical procedures you have undergone, for example: appendix removal, gallbladder removal, or any other part of your body; surgical repair to any body part, such as a hernia repair, bowel wall perforation, etc.

How painful is it? Will I need to be sedated?

Most patients report relatively minor discomfort during the procedure. Rezum therapy can be performed with oral sedatives or local anesthesia, and does not require the use of general anesthesia. Please discuss your options with your urologist for maximising your comfort during the procedure.

How quickly will I notice improvements?

Most men experience symptom relief 6 weeks after the treatment, and improvements continue for up to 3 months.

How soon can I return to regular activities?

Clinical studies show that most men return to regular activities within a few days. Your urologist will discuss this with you and make personal recommendations based on your individual health situation.

What are the risks?

Potential risks include:

  • painful or frequent urination
  • blood in urine or semen
  • decrease in ejaculatory volume
  • urinary tract infection (UTI)

During the healing phase following the procedure, patients may experience continued or worsening BPH symptoms, which may require the use of a catheter for several days. It is important to talk with your urologist about the benefits and risks associated with Rezum Therapy.

Can Rezum therapy cause erectile dysfunction?

There are no reports of new erectile dysfunction as a result of Rezum treatment; however, men with BPH are at higher risk for other potential urinary/ejaculatory issues, and there is a possibility that an underlying condition may appear following treatment with Rezum. Please discuss your individual health situation with your urologist.
