Laser treatment for BPH is also called laser prostatectomy.
The permanent effects of laser treatment on prostate tissue are vaporization and coagulation, which occur when laser energy heats prostatic tissue to 100°C. At this temperature, proteins denature and necrosis ensues, resulting in debulking of the prostate over time. This process can initially cause edema, which may increase prostate volume and make short-term catheterization necessary.
Cooled ThermoTherapy is a non-surgical, office-based prostate therapy used to treat BPH in a 30-minute treatment. Cooled ThermoTherapy uses precisely targeted microwave energy to heat and destroy enlarged prostate tissue while a cooling mechanism protects healthy, surrounding tissue. This non-surgical BPH treatment is performed on an outpatient basis and requires local anesthesia and/or oral medications. Within weeks, the majority of men notice improvements in their symptoms and overall quality of life
