Investigators from the Federal University of Minas Geraos (UFMG), Belo Horizonte, Brazil, and Rady Children’s Hospital, San Diego, CA, conducted a study to assess the accuracy of multiple classification systems for urinary tract dilatation (UTD) on postnatal ultrasound (US) in predicting future need for surgical intervention and/or kidney injury among neonates diagnosed with antenatal hydronephrosis (ANH). Study participants were infants with isolated ANH, defined as anteroposterior renal pelvis diameter ≥5 mm on a third trimester ultrasound, who were seen at the Pediatric Nephrology Unit at UFMG and followed prospectively from 1989 to 2019. The initial postnatal US was performed at approximately 14 days of age. A standard protocol was used...
