title: Percutaneous antegrade pyelography in small infants and neonates.
abstract: Percutaneous antegrade pyelography is a safe and useful alternative to retrograde pyelography in the investigation of urinary-tract malformations in the neonate or very young infant. It is preferred to arteriography in the infant with a loin mass. Satisfactory delineation of hydronephrosis or cysts is simply and directly accomplished by this method, so that more complex and less definitive investigations can often be avoided. In addition, a variety of ureteric abnormalities may be displayed.
