A method of testing the kidneys for evidence of pyelonephritis, e.g., in children suspected of having kidney damage resulting from vesicoureteral reflux. A small dose of dimercaptosuccinic acid (DMSA) linked to radioactive technetium (technetium-99m) is injected intravenously and allowed to circulate to the kidneys. Several hours later, uptake of the tracer by the kidneys is measured with a gamma camera.
