Sonography is an extremely valuable technique for renal imaging. The congenital abnormalities of fetal kidney is subdivided in two dominant categories: those in which the fetal kidney appears hydro-nehrotic  and those in which it does not. Among this in which the kidney appears hydro-nephrotic, the major task is to assign a level of obstruction (congenital uretero-pyelo-junction ,congenital megalo-ureter, bladder outlet obstruction and posterior valves) The approach to non hydroneproic abnormalities is quite different. In this second categorie we have some devastating conditions Including renal agenesis, multicystic dysplasia kidney, which are lethal when seen bilaterally. They also include many group of disease commonly referred to polycystic disease associated or not to syndrome like Meckel Gruber syndroma or Bardet  Biedel Syndroma. On this topic  we  propose some clinical cases and demonstrate the approach to be followed to the analysis of different semiotic signs urinary and associated signs to make a diagnosis of the pathology. A  family and of pregnancy women history can help to the approach of the diagnosis. We propose the follow up and the prognosis of different pathology.
