Transurethral Microwave Thermotherapy for BPH (TUMT)

Healthcare Professionals

The Prolieve® System was developed to perform Transurethral Microwave Thermotherapy for BPH. Designed for patients who are looking for an alternative to surgery or drug therapy.

A topical aqueous-based anesthetic will be applied to the opening of the urethra, a catheter will be inserted into the bladder and different methods, such as x-ray or ultrasound, may be used to verify the exact location of the equipment. A temperature monitor will be inserted to monitor the temperature surrounding the treatment area. Heat generated by microwave power and compression by the transurethral catheter balloon will be applied to the prostate gland. The catheter and temperature monitor will be removed at the conclusion of the treatment. The preparation and the procedure should take approximately 60 minutes.

The Prolieve System delivers microwave energy (heat) to the prostate for the treatment of symptomatic BPH in men with a prostate size of 20 to 80 grams, a prostatic urethra length between 1.2 cm and 5.5 cm and in whom drug therapy (e.g., Proscar® [Finasteride]) is typically used. The device uses a microwave antenna that is inside a transurethral catheter, which is placed inside the urethra to heat the prostate. At the same time, a balloon on the catheter inflates and pushes against the wall of the urethra. A heat-exchanger cartridge is responsible for warming fluid that circulates through the balloon catheter. A rectal temperature monitor is placed in the rectum near the prostate to monitor temperature surrounding the treatment area. The heating process is controlled by a computer in the machine that reads the temperature measured by the rectal temperature monitor.
