Minimally Invasive In-Office Procedure:

Rezūm™ Water Vapor Therapy is a minimally invasive in-office procedure for men looking to treat their BPH, not just the symptoms. It uses natural water vapor to reduce the size of the prostate and provide lasting symptom relief from BPH without invasive surgery or the potential side effects of prescription drugs.2

During Rezūm Therapy, which takes place during one short office visit, natural water vapor is released throughout the targeted prostate tissue. When the steam contacts the tissue and turns back into water, it releases energy, killing the excess prostate cells that squeeze the urethra. Over time, the body’s natural healing response absorbs the dead cells and shrinks the prostate. With the extra tissue removed, the urethra opens, relieving BPH symptoms while preserving sexual function.1 The procedure does not require general anesthesia and is performed under sedation.

  • Clinical studies support that Rezūm Therapy relieves BPH symptoms safely and effectively, eliminating the need for BPH medications while also preserving sexual function.It helps most men see symptom improvement within a few weeks and return to regular activities within a few days after treatment. 
  • Men with BPH who are dissatisfied with their current treatment, including prescription drugs, should consider Rezūm Therapy — a minimally invasive in-office procedure that treats the underlying condition, not just the symptoms.

All treatments have inherent and associated risks. The Rezūm System is intended to relieve symptoms and obstructions, and reduce prostate tissue associated with BPH. It is indicated for men ≥ 50 years of age with a prostate volume 30cm3 ≤ 80cm3 . The Rezūm System is also indicated for treatment of prostate with hyperplasia of the central zone and/or a median lobe. Potential risks include but are not limited to painful urination (dysuria), blood in the urine (hematuria), blood in the semen (hematospermia), decrease in ejaculatory volume, suspected urinary tract infection (UTI), and urinary frequency, retention or urgency. Patients should talk with their doctor about benefits and risks before moving forward with any treatment option.
