Abstract: A method and/or system are provided for improving kidney function and/or increasing Glomerular Filtration Rate (GFR) of the renal system, by applying acoustic and/or ultrasonic energy to one or more of the kidneys. The method suggests either focused or non-focused (or combined) energy delivery, optionally in a noninvasive approach, which could also be implemented invasively and/or by implantable device. Potential applications of this technique, include, but are not restricted to, treatment of renal disorders such as CKD (Chronic Kidney Disease) and/or AKI (Acute Kidney Injury), short term or long term intervention in kidney function for therapeutic or diagnostic purposes, modifying urine output in heart failure, modulating blood volume and/or pressure, and modulating clearance of compounds in the blood are typically difficult to extract from the kidneys, such as iodine, other imaging contrast media, and similar compounds.
