Antenatally diagnosed hydronephrosis: current postnatal management.

Author information

Department of Urology, Stanford University, Palo Alto, CA, USA.


The issue of antenatal hydronephrosis has become a routine component for the care of a pregnant woman despite limited evidence of a clinical benefit. The genitourinary tract represents the most commonly detected organ system with identified abnormalities, with antenatal hydronephrosis (ANH), being the most notable and common finding. ANH represents a spectrum, with most cases being a trivial and inconsequential finding on maternal fetal ultrasound. However, there is a correlation with increased grades of ANH being associated with increased severity of urinary tract pathology. Most patients can be managed expectantly with appropriate evaluation commenced postnatally based on severity of ANH and proper parental counseling and education. The purpose of this review was to assess current literature and guidelines pertaining to ANH and incorporate our practical interpretations of their significance.
