Micturitional disturbance in pure autonomic failure

We obtained micturitional histories and performed urodynamic studies in six patients with pure autonomic failure. All patients had urinary symptoms. U rodynamic studies showed postmicturition residuals in two, small bladder ca pacities in two, detrusor hyperreflexia in four, low bladder compliance in two, detrusor-external sphincter dyssynergia in one, neurogenic sphincter e lectromyography in three, and denervation supersensitivity of the bladder i n two. Micturitional disturbance is a common feature in pure autonomic fail ure because of peripheral and central types of abnormalities.
