Abstract

Antenatal hydronephrosis (ANH) is the most common pathology during fetal life. It was shown that ANH mostly resolves spontaneously; unresolved cases can be managed effectively by means of close follow-up. However, unfortunately the number of fetuses with ANH recommended for abortion is not rare in our country. Hydronephrosis does not always mean obstruction. It is the clinician’s responsibility to correctly determine in whom obstruction is present and when obstruction will eventually lead to renal damage. Prenatal intervention is experimental in cases with ANH. Therefore postnatal close follow-up of these cases is vital. The most important goal of postnatal follow-up is to select the patients who would benefit from early surgical intervention. This review was undertaken to discuss the issues in diagnostic evaluation of neonates with antenatal hydronephrosis.
