Urographic imaging in neonatal period: radionuclide scan and x-ray

A retrospective study of efficacy of radioisotopic renal scan intravenous urogram in 10 infants with various urologic diseases showed the scan to be more rapid and accurate in depicting the lesions. Since the radioisotopic renal scan requires less irradiation than the intravenous pyelogram, it should be used first as a screening test in infants suspected of having urologic problems.
