Transurethral Microwave Thermotherapy
Transurethral microwave thermotherapy (TUMT) is a treatment for benign prostatic hyperplasia (BPH), an enlargement of the prostate gland. It is an alternative to transurethral resection of the prostate (TURP) and other surgical procedures.
TUMT works by inserting a special catheter through the tip of the penis into the urethra. A special microwave antenna is positioned in the portion of the urethra surrounded by the prostate. Microwave energy is then emitted which heats and destroys the prostate tissue that is obstructing the urethra and causing the symptoms of BPH.
TUMT has a lower risk of complications and sexual side effects than prostate surgery, but does not offer a high patient satisfaction rate for all men. The best candidates are those with a minimally to moderately enlarged prostate of a certain shape. TUMT is generally done as an outpatient procedure with local anesthesia while the patient is awake, but sedated. Side effects include temporary urinary tract discomfort and blood in the urine and tend to resolve within a short period of time.
