Combination of implantable and transurethral ultrasound applicators for prostate thermal therapy

Abstract

This preliminary investigation demonstrates that using implantable ultrasound applicators (with energy directed away from the rectum and nontargeted tissue) in combination with a directional transurethral ultrasound applicator have potential to provide controlled thermal coagulation and necrosis of small or large regions within the prostate gland, while sparing thermally sensitive rectal tissue.
