Rezum is a minimally invasive procedure used to treat symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH). The procedure is performed in an office setting under local anesthesia, and it uses steam to shrink the enlarged prostate tissue. The procedure is performed with the help of a specialized device called the Rezum water vapor therapy system.

The procedure is performed by inserting a small tube called a cystoscope through the urethra and into the prostate. The cystoscope is used to visualize the prostate and deliver the steam to the targeted area. The steam causes the cells in the prostate to shrink, reducing the size of the gland and relieving symptoms such as difficulty urinating and frequent urination.

Before the procedure, the patient should inform the doctor of any medications they are taking and any allergies they have. The patient may be asked to do a urinary catheterization before the procedure. During the procedure, the patient may feel some discomfort or pressure, but it should not be too painful.

After the procedure, the patient may experience some discomfort or mild pain in the lower abdomen and may have to catheterize for few days. The patient will be given instructions on how to care for themselves after the procedure, including when to return for follow-up.

It's important to note that Rezum is not recommended for patients with large prostate, prostate cancer, or urinary tract obstruction. The procedure may not be as effective in patients with large prostate or prostate cancer, and it may be less effective in patients with urinary tract obstruction. Patients should discuss the benefits and risks of Rezum with a healthcare provider to determine if the procedure is appropriate for them.
