Role of Antenatal Ultrasonography in Early Detection of Fetal Urinary System Anomalies

Abstract

Congenital abnormalities of the urinary tract are the most common sonographically identified malformations approximately 20-30% of all ultrasound detected anomalies. In this study US has been successfully used for the evaluation of urinary tract congenital anomalies, although congenital urinary tract malformations comprise a broad range of structural and functional anomalies at the level of the kidney parenchyma, collecting system, bladder and urethra. Our study concludes that US especially 3D US offers a new promising imaging modality for detection and diagnosis of many congenital anomalies such as renal agenesis, polycystic kidney, hydroureter and posterior urethral valve.
