[Transition from childhood to adulthood and lumbosacral dysraphism].

The diagnosis of lumbosacral dysraphism is now made during the first year of life. Although problems due to filum lipomas are solved when the patient becomes an adult, the lipomas of the lumbar spinal cord can induce late complications. It is therefore necessary to organize a neurological, urological, and obstetrical follow-up to: screen for late retethering and/or deterioration ; preserve kidney function and monitor the consequences of the different procedures performed during childhood ; support pregnancies (delivery, prenatal screening for Currarino syndromes).
