[Ultrasonic screening of neonates]

Till june of 1990 all newborns borned in the authors' hospital were examined with ultrasound before discharge. 7582 newborns were screened during 5 years. 120 urinary abnormalities were found (1.58%). Eleven of 26 hydronephrosis were operated and one of the two multicystic kidneys. 6 unilateral agenesis of kidney, 12 unilateral hypoplasies and 30 duplex kidneys were found. 2 of the laters had hydronephrosis, too. The form of position of 37 kidneys were abnormal. 463 newborns had pyelectasy (6.1%). All were recovered spontaneously but one of them had a gross vesico-ureteric reflux. 31 cerebral malformations were found, one of them was a progressive hydrocephalus. Two of the three babies with cerebral arterio-venous malformation died because of circulatory insufficiency. There were 38 abdominal malformations: 3 hepatic and 7 splenic cysts, 3 bile stones and one neuroblastoma were the most important. 86 delivery injuries were found: 60 adrenal apoplexies, 2 hepatic ruptures and 24 intracranial hemorrhages. All healed. The ultrasound screening in the 19-20th weeks of pregnancy showed only 24% of serious renal and cerebral malformations. The authors think important to screen newborns with ultrasound.
