Five men have been treated for localized prostate cancer using transurethral ultrasound therapy, and whole mount pathology has been completed to assess the extent of thermal damage. For these cases, the temperature control accuracy and the treatment accuracy from comparison with histology are reported. Successful treatment to the prostate boundary has been observed, demonstrating the feasibility of this technique in prostates up to 71 cc in volume and with treatment radii up to 35 mm.
