How Does Rezm Water Vapor Therapy Work

Rezm Water Vapor Therapy is a non-surgical treatment that uses the natural energy stored in water vapor, or steam, to remove excess prostate tissue that is pressing on the urethra.

Rezm Therapy is typically performed right in your urologists office, or at an outpatient surgery facility and completed in one short appointment.

During each 9-second treatment, sterile water vapor is released throughout the targeted prostate tissue. When the steam contacts the prostate tissue, all the stored energy is released into the tissue. Your doctor will determine the amount of treatments you need, based on the size of your prostate.

Over time, your bodys natural healing response absorbs the treated tissue, shrinking the prostate. With the extra tissue removed, the urethra opens, reducing BPH symptoms.

Most patients begin to experience symptom relief in as soon as two weeks, and maximum benefit may occur within three months.*1,2 Patient responses can and do vary.

  • How Is Rezm Performed

    Water Vapor Treatment For Prostate

    Dr Clavell performs the Rezm therapy in the clinic or outpatient setting. The doctor performs a cystoscopy to evaluate the inside of the urinary channel. With a hand-held device, Rezm applies radio-frequency energy to a few drops of water to create vapor . That water vapor is then injected into the prostate tissue that is blocking the flow of urine from the bladder. The steam releases the energy into the cell membranes and will gently and immediately damage those cells by causing cell death. Over time, your body will absorb the treated prostate tissue and the urinary channel will re-open, relieving you of your urinary symptoms.

    What To Expect With Steam Therapy

    Steam therapy is performed under local anesthesia in the clinic. Most patients report mild discomfort during treatment but no pain. No incisions are needed.

    During the treatment, a physician inserts a small needle into the urethra and positions it within the prostate gland. In nine seconds, the needle produces a 2-centimeter-wide steam ball that shrinks surrounding prostate tissue. It does not carry heat outside the prostate or affect other surrounding tissues. The number of treatments increases with prostate size but can be completely treated during one visit.

    The needle is removed, and a temporary catheter is placed to drain urine from the bladder. This catheter is usually removed after three to five days.

    Most patients can return home the same day as steam therapy and resume regular activities within a few days. Initially, benign prostatic hyperplasia symptoms may worsen before they improve. This is because the treatment causes some swelling. Some patients start to experience fewer benign prostatic hyperplasia symptoms within two weeks, and most see improvements by six weeks.

A needle deployed from the device is inserted into the prostate. Steam is delivered along the needle in 9 second injections. The total number of injections is determined by the size of the prostate gland. The treatment takes approximately 30 minutes. A suprapubic catheter is left in the bladder for 2-4 weeks afterwards. The catheter allows for easy bladder emptying during the period of prostate swelling.

    Retreatment rates were between 3 and 5%, but no cases of ejaculatory dysfunction were caused by the method. In fact, the scientists reported that the ejaculatory bother to score improved by 31% compared with baseline.

    Twenty-seven percent of the patients studied achieved clinically relevant differences in erectile dysfunction in one year.
