Spinal dysraphisms are defined as a congenital malformation characterized by a defect in the closure of the neural tube in the caudal region. They are divided into two groups: open dysraphisms, where the skin covering is absent; and closed dysraphisms, where the skin abnormality is less obvious and diagnosis is sometimes more difficult. Both open and closed dysraphisms can cause a variety of neurological disorders, including urinary and fecal dysfunction, which is often more severe in open dysraphisms than in closed dysraphisms, which sometimes go unnoticed and may only become symptomatic during growth. As a result, urinary and fecal repercussions in closed dysraphisms are sometimes overlooked, and the literature on this subject remains scarce. The hypothesis is that a better understanding of the urinary and fecal repercussions of closed dysraphisms would allow for more appropriate and standardized follow-up of these children. The main objective of the study is to describe the urinary impact on children with spinal dysraphism, as well as how they are managed.
