Abstract
Malformations of the fetal kidneys and urinary system are common and easily visualized
and diagnosed on ultrasound. This article presents the typical sonographic findings
of these abnormalities during the various stages of pregnancy. Because malformations
of the urogenital tract often have an association with genetic diseases/ciliopathies,
these are also discussed. To complete the article, we provide a brief overview of
the normal anatomy of the kidneys and urinary system. The normal anatomy and malformations
of the genitalia will not be discussed in this article due to their complexity.
