Practical Management of Fetal Obstructive Uropathy

Urinary tract dilatation is commonly identified on antenatal ultrasound. It represents a wide range of aetiologies including obstructive uropathy. Antenatal diagnosis and a consistent, evidenced based approach to follow up is essential in reducing neonatal morbidity and mortality. We present a summary of the current literature and a practical guide to the management of obstructive uropathy, including the normal sonographic features of the developing fetal urinary tract, antenatal diagnostic criteria and the approach to postnatal investigation and management.
