Sonablate HIFU will ablate any tissue that the physician targets with the device during treatment planning. After the physician reviews your diagnosis, he or she will make a recommendation on the best course of treatment. This recommendation, based on your pathology report and imaging, will include how much of the prostate should be treated.In some cases, the entire prostate will be targeted, which would include the tumor as well as any other tissue in the prostate. Think of it as having the prostate removed, without a single incision. However, some physicians, who work with advanced, MRI- guided imaging for diagnosis, can determine the exact location of the tumor in the prostate and may use HIFU to only treat the tumor leaving other tissue in the prostate intact; this is referred to as partial tissue ablation, or focal therapy.
