Urodynamic characterization of incontinence in the elderly by bladder volume

Incontinence in the elderly patient usually is of the urgency pattern owing to inappropriate detrusor contraction often termed detrusor instability. We herein describe a bladder volume-based method of urodynamic assessment that may help to characterize subsets of incontinent patients with detrusor instability. The conventional parameters of flow, pressure and electromyography are more difficult to measure and may be less appropriate for selection of therapy.
