Rezum is a Minimally Invasive Surgical Treatment (aka MIST) for BPH or enlarged prostate that is performed in the office setting or as an outpatient surgery. Rezum uses heat energy stored in steam to treat enlarged prostate tissue that is obstructing urine flow and causing bothersome symptoms such as urinary frequency, urgency, weak flow, hesitancy and waking at night to urinate.
Rezum uses a hand-held device introduced into the urethra through a cystoscope. Radiofrequency energy is used to heat up a small amount of water into steam that is then injected through the device directly and precisely into the enlarged or obstructing prostate tissue. The steam is immediately converted back into a water state and the energy is released into the cell membranes of the prostate tissue causing a gentle cell death. Over time, the obstructing prostate tissue will be absorbed through a natural healing process allowing the bladder to empty better and improving urinary symptoms.
