Ultrasound diagnosis of fetal hypospadias: Accuracy and outcomes

Our single center experience with the fetal ultrasound diagnosis of hypospadias demonstrates a high positive predictive value for a penile anomaly (21/25, 84%), and a moderately high positive predictive value for the specific diagnosis of hypospadias (18/25, 72%) when compared with the postnatal diagnosis.Table.
