The technology

Powered by convective water vapour energy, the Rezūm™ System delivers targeted, controlled doses of stored thermal energy in water vapour directly to the region of the prostate gland, with the obstructive tissue causing lower urinary tract symptoms (LUTS).

Each 9-second treatment uses 0.42ml of heated sterile water vapour, which rapidly and uniformly disperses through the tissue interstices. The condensation of water vapour releases stored thermal energy. Cell membranes are denatured, thereby causing immediate cell death, the vasculature is closed, and there is denervation of the alpha-adrenergic nerves within the treatment zone providing you with an efficient, uniform, predictable treatment.

Over time, this ablated tissue is reabsorbed by the body’s natural healing response, reducing the volume of tissue, allowing the urethra to open and thus relieving LUTS.

Side effects

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)
• Urinary frequency, retention or urgency
