Microwave Therapy (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. In transurethral microwave therapy (TUMT), an instrument (called an antenna) 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 antenna 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 usually does not require an overnight stay in the hospital. A general or spinal anesthetic is needed during the procedure. Microwave therapy is also known as cooled thermal therapy or by the name of the equipment used.
You are generally able to go home after surgery. 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. You can generally return to work 1 to 2 days after treatment. Sexual activity can be resumed 1 to 2 weeks after surgery.
