Pediatric neurourology.

Children with voiding disturbances or neurologic dysfunction of the lower urinary tract present challenges to the practicing clinician. With careful clinical and radiologic evaluation, many of these disturbances can be managed. Complex situations, however, generally require expert urodynamic evaluation to delineate the cause of the bladder dysfunction and to guide management. These investigations combined with long-term follow up should provide new insights for further improvement in the management of neurogenic bladders in children. Urodynamic studies also have given us insights into the pathophysiology of abnormal voiding states secondary to dysfunctional bladders in children with posterior urethral valves, the prune belly syndrome, and the Hinman syndrome.
