What is a TUMT?

A TUMT is transurethral microwave therapy.

Transurethral microwave therapy (TUMT) is a minimally invasive procedure done for patients who are experiencing symptoms from prostate enlargement (BPH). After oral sedation and local anesthesia, a specialized catheter with microwave energy delivery capability 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 through the catheter and 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 over a preset threshold, the treatment is turned off automatically until the temperature goes back down.

The microwave energy heats the prostate and coagulates the prostate BPH tissue, shrinking it away from the urethra and opening up the prostate channel. The heating part of the procedure takes about 30 minutes and is done in a single session in the doctor’s office. Patients are then dismissed to home with a small catheter in the bladder for about 7 days, while the swelling subsides.

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 or need something more than medicines for the treatment of their symptoms. It is 80% successful and has the advantage of an office-based procedure done with mild sedation, avoiding the risks of general anesthesia.

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?

The stream may be weak at first when the catheter is removed. On occasion, the catheter will need to be reinserted temporarily while the prostate continues to shrink. 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.

You can generally return to work 1 to 2 weeks after treatment. Sexual activity can be resumed 2 to 3 weeks after the procedure.

When should I seek advice from my physician?

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

  • Fevers that are consistently above 101 degrees Fahrenheit.
  • Blockage or difficulty with the catheter
  • Large amounts of bleeding
  • Uncontrolled pain or nausea
  • Inability to Urinate
