title: Reflexes of the external urethral sphincter in children.
abstract: The electromyographic responses in the external urethral sphincter to electrical stimulation of the pudendal nerve and stretch of the external sphincter were analyzed in a pediatric population; the population included a group with recurrent urinary tract infections and a group with complete or almost complete upper spinal cord lesions. Electrical stimulation produced a response of reflex nature mediated in the sacral spinal cord, frequently beginning with two components that could be individually characterized and that behaved similarly to a flexor reflex. The response produced by stretch appeared to be similar to that produced by electrical stimulation.
