title: The use of urodynamic studies to assess the effect of pharmacological agents with particular references to alpha-adrenergic blockade.
abstract: A method of studying the effect of drugs on the lower urinary tract is described, using cord-injured patients with detrusor hyperreflexia. In this study 19 patients received intravenous phentolamine. This alpha-adrenergic blockade produced a significant reduction in the maximum voiding detrusor pressure, voided volumes and peak flow rates with no reduction of outflow tract obstruction.
