ABSTRACT
Neurogenic bladder in the neonate can be divided into three groups-primary, secondary, and idiopathic. Primary neurogenic bladder develops as a result of a lesion at any level in the central nervous system, cerebral cortex, and spinal cord, or in the peripheral nervous system. It is unusual to make a diagnosis of neurogenic bladder antenatally on the basis of the ultrasound (US) appearances of the renal tract. For the vast majority of patients, the diagnosis of neurogenic bladder is assumed following the finding of evidence of spinal dysraphism, open or closed, on antenatal scan. The autonomic and somatic nervous systems are involved in the innervations of the bladder and sphincter; the parasympathetic component of the autonomic innervations is derived from the sacral segments of the spinal cord. There are many classifications describing neurogenic bladder dysfunction. Most of these classifications are dependent on the site of the neurological lesions, well adapted to adult pathology but not to congenital spinal lesions.
