Prior to HIFU, patients usually have lab work (Complete Blood Count (CBC), Complete Medical Panel, Urinary Analysis with culture if indicated by your physician) and an EKG in preparation for undergoing anesthesia. If the patient has any significant medical history, he should see his cardiologist or primary physician. The HIFU procedure itself causes no significant bleeding or swings in blood pressure, etc. A nurse will send detailed information after the procedure has been scheduled regarding diet, medications and any additional lab work or tests that may be required.
