Intravenous Pyelography in the Deferential Diagnosis of Renal Masses in the Neonatal Period

Abstract

Intravenous pyelography was performed in 38 infants with palpable abdominal masses in the neonatal period. Accurate preopera tive diagnoses of a variety of renal lesions was achieved by this method in 28 of the infants. With eight of the others, retrograde pyelography proved useful. Two infants died before this procedure could be performed.
