[Prenatal diagnosis of multicystic dysplastic kidney: about 18 cases].

Multicystic dysplastic kidney (MCDK) is the most common Congenital Abnormalities of Kidney and Urinary Tract (CAKUT) in clinical practice. Its etiology and pathogenesis are still controversial and obstruction is a generally accepted causative assumption. Obstetric ultrasound is the gold standard for prenatal diagnosis and for the detection of other associated malformations. Prenatal management is based on ultrasound monitoring of pregnancy, of the disease, of the occurrence of other anomalies and of the amount of amniotic fluid. This study aims to report our experience in the Department of Gynecology-Obstetrics 2 at the University Hospital Hassan II-Fez in order to clarify the epidemiology of MCDK, highlight the role of obstetric ultrasound in positive and etiological diagnosis while describing the various sonographic appearances. It is essential to schedule for screening tests during pregnancy in order to assess the evolution of the disease diagnosed in the prenatal period, to implement a strategy in postpartum care and to establish a prognosis.
