title: Bladder neck dysynergia in spinal cord injury.
abstract: Urodynamic evaluations were performed in 43 male patients with spinal cord injuries, before any therapeutic decisions, and a minimum of 5 mo following the injury. Results were subdivided according to level of injury. Mean detrusor contraction pressures, incidence of detrusor-sphincter dysynergia (DSD), and incidence of detrusor-bladder neck dysynergia (DBND) were calculated. The incidence pattern of DBND was found to follow closely the incidence pattern of DSD, with the highest incidence among the upper thoracic injuries, considerably more than among the cervical injuries. A significantly higher resting detrusor pressure differential was found among the patients with DBND. This was felt to represent sympathetic dysfunction and poor accommodation and is proposed to be secondary to adrenergic detrusor neoinnervation.
