Summary

Congenital genitourinary tract anomalies are some of the most commonly identified prenatal abnormalities, being identified in between 1 in 250 and 1 in 1000 pregnancies. They consist of a wide spectrum of heterogeneous malformations. Obstructive uropathies account for the majority of these abnormalities. the second-trimester detailed scan (often at 18+0–21+6 weeks) is the examination in which the majority of genitourinary abnormalities are diagnosed. However, with the widespread use of first-trimester ultrasound screening, severe renal anomalies and “megacystis” are being noted between 11+0 and 13+6 weeks. Additionally, third-trimester ultrasound may reveal late-onset uropathies, often associated with changes in liquor volume.
