Polycystic kidney disease is a common genetic cause of chronic kidney disease, characterized by the formation of multiple cysts in the kidneys and other organs, occurs in 1 in 20,000 live births. 30 to 50% of affected newborns die shortly after birth because of respiratory and renal insufficiency. This study reports the case of a newborn with polycystic kidney disease diagnosed by obstetric ultrasound at 26 weeks of gestation and kidneys anhidramnios due to increased volume and appearance "in sponge.
