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
