CALCIFIED INTRALUMINAL MECONIUM IN NEWBORN MALES WITH IMPERFORATE ANUS: ENTEROLITHIASIS IN THE NEWBORN

Five cases are reported and reference is made to 3 previous similar cases of calcified intraluminal meconium in newborn males with "imperforate anus." A rectourinary fistula was found in most of the patients; none of the cases had meconium peritonitis. The calcifications may develop in areas of prolonged stasis; the possible added role of the mixture of urine and meconium in utero is raised.
