Rezūm™ Water Vapor Therapy

Understanding your treatment

RezūmTM Water Vapor Therapy treats excess prostate tissue causing benign prostatic hyperplasia (BPH), also called an enlarged prostate. It uses the natural energy stored in steam to shrink the prostate, so urine can flow freely. There are no incisions, and typically it does not require general anesthesia. It has also been shown to preserve sexual function through five years after the procedure.1

How it works

Rezūm Water Vapor Therapy can be performed in your urologist's office, or at an outpatient surgery facility, and is completed in one appointment. The procedure consists of a series of 9-second treatments, during which sterile water vapor is released throughout the targeted prostate tissue. When the steam contacts the prostate tissue, the stored energy is released into the tissue. Over time, your body's natural healing response absorbs the treated tissue, shrinking the prostate. With the extra tissue removed, the urethra opens, reducing BPH symptoms. Your doctor will determine the number of treatments you need based on the size of your prostate.


Potential Benefits of Rezūm™ Water Vapor Therapy

After therapy, patients begin to experience BPH symptom relief in as soon as 2 weeks, with a  greater benefit occurring within approximately 3 months.*2

Other potential benefits of Rezūm Therapy include:

  • Surgical retreatment rate: after 5 years, only 4.4% of patients needed another surgery for BPH symptoms1
  • Significant and sustained BPH symptom relief through 5 years¹
  • Can be done in office, under local anesthesia or conscious sedation¹
  • No permanent implant
  • Preserves sexual function1
  • FDA cleared; included in the American Urological Association guidelines for BPH treatment

Knowing the risks and side effects

Like all medical procedures, there are risks associated with Rezūm Water Vapor Therapy. The Rezum System is intended to reduce prostate tissue and relieve urinary symptoms caused by an enlarged prostate, or BPH (Benign Prostatic Hyperplasia), for men 50 years of age or older.

With all medical procedures, there are risks associated with the procedure and the use of the device. The risks include but are not limited to painful or frequent urination, blood in the urine or semen, inability to urinate or completely empty the bladder, post-op discomfort, urinary tract infection (UTI), decrease in ejaculatory volume, and an urgent need to urinate.

During the healing phase following the procedure, urinary symptoms may continue or worsen, which may require the use of a catheter for several days.

Be sure to talk with your doctor so that you thoroughly understand all the risks and benefits associated with the use of the device.


Recovering from your procedure

After your procedure, be sure to ask your doctor about returning to normal physical activities. They will guide you according to your treatment and existing health conditions.


Regular follow-up visits

You may have a follow-up scheduled with your doctor within the first few days after the procedure to remove your catheter and check your symptoms and recovery progress. 

It’s important to maintain follow-up visits, even if you’re feeling well. During these visits, your doctor can monitor your progress, evaluate your medications, check the status of your overall health and determine the outcome of your treatment.


*Dependent on individual clinical situations and healing responses. Patient responses can and do vary.
