Rezūm, which has been featured on The Doctors and in The Wall Street Journal, is one way to alleviate BPH symptoms. Rezūm essentially utilizes steam to treat an enlarged prostate. Sterile water, which is heated into steam, is delivered in controlled doses to areas of prostate tissue. The heat eventually kills the extra tissue, which is then processed by your body. With the extra tissue gone, there is less pressure on your urethra, decreased discomfort and improved urination.
