Rezūm Therapy is performed right in the clinic, and completed in one short appointment. The actual procedure takes only minutes; however, plan on spending approximately two hours for the entire appointment due to recovery and observation after the operation. Depending on the size of the prostate, the procedure consists of two to seven injections, each nine seconds long.

Upon arriving, the patient will be instructed to eliminate urine, and the bladder is then checked. If there is still more urine in the bladder, it is drained to avoid having to drain it during the procedure.

Here are  step-by-step instructions on what to expect from the procedure itself:

• Both the prostate and the penis are numbed. The doctor will use a hand-held device that passes through the urethra to reach the prostate. 
• A tiny amount of steam is injected into the prostate to impact part of the swollen prostate tissue that is putting pressure on the urethra and causing the bothersome symptoms of BPH.
• 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.
• Because of the initial swelling, a catheter is then inserted, which will remain for two to five days. The catheter is hooked to a bag that stays on the leg and is covered by pants. A driver is required to take the patient home.

Over time, your body’s 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. Patient responses can and do vary.
