Rezūm is a transurethral needle ablation* procedure to treat benign prostatic hyperplasia (BPH) that can be performed in a clinic or out-patient setting. Using a hand-held device, Rezūm delivers radiofrequency generated thermal therapy, in the form of water vapor, directly to the extra prostate tissue that is causing symptoms such as frequency, urgency, irregular flow, weak stream, straining and getting up at night to urinate. The radiofrequency energy transferred by the water damages the cells, causing cell death. Over time, your body will absorb the treated tissue through its natural healing response.
Inside a hand-held device, radiofrequency energy is applied to a few drops of water to create vapor (steam). The water vapor is injected into the prostate tissue that is blocking the flow of urine from the bladder, where it immediately turns back to water, releasing the energy stored in the vapor into the cell membranes. At this point, the cells are gently and immediately damaged, causing cell death. Over time, your body will absorb the treated tissue through its natural healing response.
*transurethral needle ablation describes the minimally invasive delivery of the device through your urethra, where a needle will be placed into the extra prostate tissue and this tissue will be destroyed with the radiofrequency created thermal energy.
