Transurethral Microwave Therapy (TUMT)

What is a TUMT?

A TUMT is transurethral microwave therapy.

In transurethral microwave therapy (TUMT), an instrument that sends out microwave energy is inserted through the urethra to a location inside the prostate. Microwave energy is then used to heat the inside of the prostate. Cooling fluid is circulated around the microwave apparatus to prevent heat from damaging the wall of the urethra. To prevent the temperature from getting too high outside the prostate, a temperature sensor is inserted into the man's rectum during the procedure. If the temperature in the rectum increases too much, the treatment is turned off automatically until the temperature goes back down.

The temperature becomes high enough inside the prostate to kill some of the tissue. As this part of the prostate heals, it shrinks, reducing the blockage of urine flow.

This treatment is done in a single session. It can be done as an office procedure. It usually does not require an overnight stay in the hospital.

What is the purpose of a TUMT?

TUMT is done to help relieve the symptoms of benign prostatic hyperplasia (BPH). It is an option for men who want more than medicines for treatment of their symptoms.

This procedure is not recommended for men with prostate cancer or for men who are suspected of having prostate cancer.

What are common symptoms following my TUMT?

You may not be able to urinate and may require catheterization to drain your bladder. For most men, this lasts for a week or less. You may also have to take antibiotics or anti-inflammatory medicines.

Erection problems and retrograde ejaculation (ejaculation backward into the bladder) can occur but are uncommon. Other potential issues are persistent irritation of the urethra and blood in the urine.1

You can generally return to work 1 to 2 days after treatment. Sexual activity can be resumed 1 to 2 weeks after surgery.

When should I seek advice from my physician?

You should contact your physician if you develop any of the following:

  1. Fevers that are consistently above 101 degrees Fahrenheit.
  2. Drainage of pus.
  3. Large amounts of bleeding
  4. Uncontrolled pain or nausea.
  5. Inability to Urinate
