Abstract

Approximately 3 million maternal ultrasound examinations are performed each year in the United States [1]. They are commonly performed as a routine examination during pregnancy, permitting the early identification of numerous congenital anomalies in the developing fetus. Based on large population studies, the incidence of congenital anomalies detected by prenatal ultrasound examinations is 1% to 2% [2], with urinary tract malformations being the most frequently detected anomalies [3]. Dilation of the collecting system (ie, hydronephrosis), the hallmark of urinary tract obstruction, represents approximately 50% of all abnormalities detected by ultrasound examination [4].
