TherMatrx® Thermotherapy (Microwave Therapy)

Men with enlarged prostate symptoms who want to stop taking medication or whose medication no longer improves symptoms may elect to have one of the minimally invasive treatments such as thermotherapy. Thermotherapy uses state-of-the-art tools and techniques to reduce or eliminate symptoms of enlarged prostate (BPH). Heat is used to destroy excess prostate tissue. Thermotherapy may help patients avoid the risks and complications of surgery.

TherMatrx® is a minimally invasive (non-surgical), thermotherapy procedure performed in the office that uses heat delivered through a microwave antenna. This outpatient procedure requires local anesthesia. A mild sedative or pain reliever may be given to help the patient relax and make him as comfortable as possible during the procedure.

A urethral catheter containing the microwave antenna is passed through the urethra and prostate gland and is secured by a balloon at the tip of the catheter that passes through the uretheral sphincter. Localized microwave energy is delivered at a temperature high enough to relieve BPH (benign prostate hyperplasia) symptoms, including difficult, frequent, or urgent urination. The procedure lasts approximately 1 hour.

Following the procedure, a catheter is inserted to drain urine from the bladder for a few days. Once the catheter is removed, the patient can resume normal activity. Symptoms improve in 4 to 6 weeks. Healing takes 6 weeks to 3 months.

Possible complications include incontinence, pain during urination, and urinary retention. Most complications resolve during the healing period without intervention.
