Transurethral microwave therapy (TUMT) is an outpatient procedure to treat urinary symptoms caused by an enlarged prostate, also known as benign prostatic hyperplasia (BPH). It's used less often now than it was in the past and has generally been replaced by newer treatments.
During TUMT, a small microwave antenna is inserted through the tip of your penis into the tube that carries urine from your bladder (urethra). The antenna is extended until it reaches the area of the urethra surrounded by the prostate. Your doctor then uses the antenna to emit a dose of microwave energy that heats up and destroys excess prostate tissue blocking urine flow.
TUMT is one of several options for treating an enlarged prostate. To determine the best treatment choice for you, your doctor will consider how severe your symptoms are, what other health problems you have, and the size and shape of your prostate.
Before doing any enlarged prostate procedure, your doctor may want to do a test that uses a visual scope to look inside your urethra and bladder (cystoscopy). This allows the doctor to check the size of your prostate and examine your urinary system. Your doctor may also want to do other tests, such as blood tests or tests to measure urine flow.
