Transurethral microwave therapy (TUMT) is an outpatient procedure to treat urinary symptoms caused by an enlarged prostate. It's generally used for men with small- to moderate-sized prostates.
A small microwave antenna is inserted through the tip of your penis into the tube that carries urine from your 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 excess prostate tissue blocking urine flow.
TUMT is one of several minimally invasive treatment options for an enlarged prostate, a condition known as benign prostatic hyperplasia (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.
