Rezum (Water Vapor Therapy for BPH)
What This Treatment Is For
Rezūm™ water vapor therapy is a minimally invasive, office-based procedure used to treat benign prostatic hyperplasia (BPH), also known as prostate enlargement. It uses targeted water vapor (steam) energy to shrink excess prostate tissue and relieve urinary symptoms without the need for major surgery.
Who It’s For
Rezūm is ideal for men with moderate urinary symptoms such as weak urinary flow, urgency, frequent nighttime urination, or incomplete bladder emptying. It is a good option for patients who want to avoid long-term medication or more invasive procedures like TURP. Rezūm is typically suitable for prostate sizes up to 80cc.
How the Procedure Works
Performed as an outpatient procedure, Rezūm uses a small device inserted through the urethra to deliver steam injections into the prostate. Each treatment lasts just seconds. The prostate tissue gradually shrinks over the following weeks. Local anesthesia and light sedation are commonly used. A urinary catheter is often placed for 2–5 days afterward.
