Tulsa Pro uses some of the same ultrasound technology for the ablation, but they are not alike. Tulsa Pro can handle a person with a fair amount of BPH, HIFU can not. HIFU the lesion has limited locations that it can reach so the lesion is best if it is near the rectum, as it is done that way and only reaches a limited area in the prostate. There are other limits some places put on HIFU, and some places put limits on Tulsa too. These are limits the maker of the equipment has not put on using it, as the places doing studies almost always put more limits on who they accept. So bottom line is if you go to a place that is part of a study they may not accept you, where-as private place might.
