Rezūm® Therapy

1. What is Rezūm Therapy?

Rezūm® Water Vapor Therapy is a minimally invasive treatment for benign prostatic hyperplasia (BPH), also known as an enlarged prostate. It uses natural water vapor (steam) to shrink excess prostate tissue that is blocking urine flow.

2. How does Rezūm work?

During the procedure, sterile water vapor is injected directly into the enlarged prostate tissue. As the steam condenses, it releases energy that causes the targeted prostate cells to die. Over the following weeks, the body absorbs and removes the treated tissue, relieving urinary symptoms.

3. Who is a candidate for Rezūm?

Rezūm is ideal for men who:

  • Have moderate to severe urinary symptoms from BPH

  • Prefer a non-surgical, outpatient option

  • Want to preserve sexual function, especially ejaculation

  • Are seeking an alternative to long-term medications or more invasive surgery

It is suitable for prostates up to about 80 grams in size.

4. What are the benefits of Rezūm?

  • Performed in-office with no general anesthesia required

  • Preserves sexual function in most men

  • Rapid symptom relief, often within 2–6 weeks

  • Minimal downtime and quick return to normal activities

  • Reduces or eliminates the need for BPH medications

5. What is the procedure like?

  • Takes about 10–15 minutes

  • Performed under local anesthesia or light sedation

  • A small device is inserted into the urethra to deliver the steam

  • Most patients go home the same day

  • A temporary catheter is often placed for 3–5 days after the procedure

6. What is the recovery like after Rezūm?

  • You may experience urinary urgency, frequency, or mild discomfort for a few days

  • Blood in the urine and mild burning during urination are common and temporary

  • Most men return to normal activities in a few days to a week

  • Symptom improvement is gradual, with full results typically seen by 3 months

7. Are there risks or side effects?

Possible side effects are usually mild and temporary, including:

  • Urinary discomfort or burning

  • Blood in the urine or semen

  • Urinary tract infection

  • Temporary inability to urinate (retention)

Most side effects resolve within a few weeks.

8. How effective is Rezūm Therapy?

Clinical studies show that Rezūm provides lasting relief of BPH symptoms for at least 5 years. Many men can stop taking BPH medications after treatment.
