A urethral catheter (40) includes a passageway (62) for a radiating element (86). The passageway (62) is exposed through a sidewall (68) of the catheter (40) to permit the radiating element (86) to exit the catheter (40) and enter prostate tissue (14) at a preselected location. Electromagnetic energy supplied to the radiating element (86) causes localized heating of the prostate tissue (14) which surrounds the radiating element (86).
