Rezūm Water Vapor Therapy for Enlarged Prostate (BPH)

An enlarged prostate — benign prostatic hyperplasia, or BPH — causes a weak stream, frequent urination, getting up at night, and trouble emptying the bladder. For men who want relief without major surgery or a lifetime of daily pills, Rezūm offers a minimally invasive option that uses the natural energy of water vapor (steam) to shrink the tissue that is blocking urine flow.

Now offered in-office by Dr. Gheiler

Dr. Edward Gheiler, MD, FACS now performs Rezūm water vapor therapy in his Miami office — giving men another minimally invasive way to treat an enlarged prostate close to home, without the operating room.

How Rezūm works

Rezūm delivers a few seconds of sterile water vapor directly into the overgrown prostate tissue. Each treatment lasts only seconds. As the treated tissue is naturally reabsorbed over the following weeks, the prostate shrinks and the urinary channel opens up. Because the therapy targets only the excess tissue, it is designed to reduce the risk of sexual side effects compared with some other BPH treatments — a common reason men choose it. Erectile and ejaculatory outcomes still vary from man to man.

Is Rezūm right for you?

Rezūm is generally considered for bothersome, moderate-to-severe urinary symptoms from a moderately enlarged prostate. It may be a good fit if you would rather not stay on daily medication and want a minimally invasive option that is designed to reduce the risk of sexual side effects compared with some other BPH surgeries — though it is not right for every anatomy, and men with certain implanted urologic devices may need a different approach. Dr. Gheiler will evaluate your prostate size, symptoms, and overall health and explain honestly whether Rezūm — or another approach such as GreenLight Laser Therapy — is the better path for you.

What to expect

The vapor treatments take only seconds each, and the full procedure is done in a single office visit. Afterward it is normal to have temporary urinary symptoms for a few weeks while the prostate heals; some men use a catheter for a short time. Symptom relief builds gradually over the weeks that follow as the treated tissue is reabsorbed. Dr. Gheiler and his team will review aftercare with you in detail.
