**8. Conclusions**

The ultrasound diagnosis of renal and urinary tract abnormalities is generally based on the exclusion criteria, by comparison with the normal imaging one. In most cases, kidney or urinary tract abnormalities are diagnosed considering the appearance of amniotic fluid abnormalities, visualization of kidney size abnormalities or dilated appearance of the urinary tract. Congenital kidney abnormalities are often associated with the urinary tract malformation, and there is a wide range of anomalies resulting from disorders in the development process. It is important to differentiate abnormalities incompatible with life (as they require interruption of pregnancy) and asymptomatic/paucisymptomatic diseases in the postnatal life.

The genitalia anomalies must be treated by a multidisciplinary team that includes neonatologists, endocrinologists, urologists, perinatologists and medical geneticists with expertise in this field.
