[Positive diagnosis of Potter's syndrome by ultrasonography. A case report]

Potter's syndrome is a rare disorder but on which should not be overlooked. Ultrasound signs such as oligoaminos, retarded intra-uterine growth. (R.I.U.G.) and failure to detect the bladder and kidneys constitute fairly clear signs. Early and specific diagnosis leads to therapeutic pregnancy termination. This allows the parents to avoid the painful and late birth of a malformed child.
