The ability of radionuclide techniques to reveal poorly functioning kidneys has been demonstrated, primarily with 131I orthoiodohippurate. Technetium 99m chelate and iron ascorbate complex have been used with some success in similar problems. In most situations it is sufficient to ascertain the presence and size of the poorly functioning kidney, which often requires delayed images of 2 to 3 hours or more. In a 5 year old boy a large hydronephrotic sac was completely filled on delayed Tc 99m diethylenetriamine pentaacetic acid (DTPA) studies, allowing the diagnosis to be established in a child with an asymptomatic abdominal mass.
