Overview

Transurethral microwave thermotherapy (TUMT) is an outpatient procedure to treat urinary symptoms caused by an enlarged prostate, a condition known as benign prostatic hyperplasia (BPH). TUMT is generally considered a safe procedure with a low risk of side effects. It's generally used for men with other health conditions for whom more invasive surgery isn't recommended.

A small microwave antenna is inserted through the tip of the penis into the tube that carries urine from the bladder (urethra). Your doctor extends the antenna until it reaches the area of the urethra surrounded by the prostate. The antenna emits a dose of microwave energy that heats and destroys the excess prostate tissue that is blocking urine flow.

TUMT is one of several minimally invasive treatment options for BPH. To determine the right treatment for you, your doctor will consider the severity of your symptoms, any other health problems you have, and the size and shape of your prostate.
