Rezum water vapor therapy is a minimally invasive option for urinary symptoms caused by benign prostate enlargement (BPH). During the procedure, a urologist delivers controlled doses of water vapor into selected prostate tissue. The body gradually absorbs the treated tissue, which may reduce blockage of the urinary channel. Symptom improvement can take time, and a urologist will assess whether the procedure is suitable for you.
A small instrument is passed through the urethra. The urologist releases controlled doses of water vapor into selected prostate tissue. The body's healing response gradually absorbs the treated tissue, which can open the urinary channel over time.
Your symptoms, prostate anatomy, health and treatment goals help determine whether Rezum may be an option. Ask about the expected timeline for symptom changes, catheter use, alternatives and follow-up care.
Urinary discomfort, urgency, blood in the urine or temporary difficulty passing urine may occur during recovery; some patients need a catheter for a period after treatment. Infection and other complications are also possible. Your urologist will explain the risks and recovery plan for you.
