Rezum Therapy is a minimally invasive treatment that uses water vapour (steam) to relieve the symptoms of benign prostatic hyperplasia (BPH), or enlarged prostate. Using natural thermal energy, this therapy reduces excess prostate tissue that causes urinary blockage—without cutting or removal of tissue.

The procedure is performed using a handheld device inserted via a small telescope (cystoscope) into the urethra. The radiofrequency-generated steam targets the enlarged prostate, and over time, your body naturally absorbs the treated tissue, restoring urinary flow.

At Urology SA, Dr Jehan Titus and Dr Jimmy Lam are highly skilled in Rezum therapy and offer the full range of modern BPH treatments. They provide personalised consultations to help determine the best option for each patient.

Who is Suitable for Rezum Therapy?

Rezum Therapy is appropriate for men who:

• Experience urinary symptoms due to BPH:
  • Weak urine stream
  • Stop–start urination
  • Straining to begin urination
  • Frequent urination or urgency
  • Incomplete bladder emptying
  • Night-time urination (nocturia)
• Want to avoid long-term medications (due to side effects or cost)
• Prefer a minimally invasive, low-risk treatment
• Want to preserve sexual function

Advantages of Rezum Therapy

• Minimally invasive – no cutting, no tissue removal
• Clinically proven and endorsed by the American Urological Association
• Durable symptom relief, with over 4 years of positive clinical data
• Faster recovery and return to normal activities (within 24–48 hours)
• Short procedure time – often under 10 minutes
• Preservation of sexual function (low risk of retrograde ejaculation)

How is the Procedure Performed?

• Performed under general anaesthetic
• No skin incisions required
• A cystoscope guides a handheld device into the urethra
• Radiofrequency-generated steam is delivered to the prostate
• The procedure takes 10–15 minutes in most cases
• Usually performed as day surgery, though an overnight stay may be required

What to Expect After Rezum Treatment

• A catheter is typically needed for 3–5 days to allow swelling to subside
• Discomfort, urinary urgency, and blood in urine or semen are common for 4–6 weeks
• Light activities can resume in 24–48 hours
• Maximum benefit may take 8–12 weeks as the body clears treated tissue

Outcomes of Rezum Therapy

• Improved flow, pressure, and bladder emptying within 2–4 weeks
• Frequency and urgency symptoms typically improve within 3 months
• Sexual function is preserved in the majority of patients

Post-Operative Care 

What to Expect

• You will go home with a urethral catheter for several days
• Only your urologist should advise on catheter removal
• After catheter removal, you may experience:
  • Burning with urination
  • Increased urinary frequency
  • Blood in urine or semen
