Rezūm Water Vapor Therapy

Rezūm uses a few seconds of steam to shrink an enlarged prostate — an in-office treatment that takes minutes, needs no incision, and lets most men keep their sexual function.

What is Rezūm water vapor therapy?

Rezūm is a minimally invasive, in-office treatment for an enlarged prostate (BPH). It uses a few seconds of targeted water vapor — steam — to gently shrink the prostate tissue that's blocking urine flow. There's no cutting and no removal of tissue; over the following weeks, the body naturally absorbs the treated tissue and symptoms ease.

What to expect

  • Done in the office in minutes
  • Local anesthesia, light sedation as needed
  • Home the same day
  • Symptoms improve over a few weeks

Rezūm sits in the minimally invasive middle of the BPH treatment ladder — a step up from medication, without going to the operating room.

Who it's for

Rezūm can be a good fit for men whose BPH symptoms aren't controlled by medication but who want to avoid surgery, and who'd like to preserve sexual function. Whether it's the right choice depends on your prostate size and anatomy — something we confirm at an evaluation.

Common questions

What is Rezūm?

Rezūm is an in-office treatment for an enlarged prostate that uses targeted water vapor (steam) to shrink the overgrown tissue pressing on the urethra. It's quick, minimally invasive, and doesn't require an incision.

How long does Rezūm take?

The treatment itself usually takes just a few minutes in the office. Patients typically go home the same day, with symptoms improving over the following weeks as the body absorbs the treated tissue.

Is Rezūm painful?

Rezūm is done with local anesthesia and mild sedation as needed. Most men describe only minor discomfort, and any temporary urinary symptoms afterward usually settle within a couple of weeks.

Does Rezūm preserve sexual function?

Rezūm is designed to relieve BPH symptoms while preserving sexual function for most men. We'll go over what to expect for your specific situation at your visit.
