    Abstract:
    OBJECTIVE: To explore the Video-urodynamic characteristics of various neurogenic bladder. METHODS: A total of 1800 patients with neurogenic bladder were included in our study from December 2002 to June 2008. All patients underwent Video-urodynamic studies. Urodynamic data was collected and analyzed. RESULTS: Urodynamic study showed detrusor overactivity in 71%, of which 60% with uninhibited sphincter relaxation, and acontractile detrusor in 29% stroke patients. No upper urinary tract deterioration was found in all 42 stroke patients. Detrusor overactivity without sphincter dyssynergia was found in 70% patients with head trauma. Seven patients with Parkinson disease showed detrusor overactivity, of which 3 with delayed sphincter relaxation. Detrusor overactivity was found in 91% and detrusor sphincter dyssynergia in 83% supra-sacral spinal cord injured patients. Acontractile detrusor was found in 73% patients with conus medullaris and cauda equina injury. Overall, upper urinary tract changes were found in 12% and vesicoureteral reflux in 4% spinal cord injured patients. Urodynamic study showed acontractile detrusor in 81%, reduced compliance in 86%, upper urinary tract changes in 55% and vesicoureteral reflux in 33% patients with myelodysplasia. Most patients (92%) with protruded lumbar disc showed detrusor areflexia. Normal bladder compliance was found in 88% patients with protruded lumbar disc. Urodynamic study showed reduced bladder sensation in 81% and detrusor under-activity in 76% patients with diabetic urinary bladder disease. CONCLUSIONS: Video-urodynamic study can provide the most detailed information about the bladder dysfunction. It is the most valuable examination before treatment of patients with neurogenic bladder.
