Urinary Bladder Response to Unilateral Stimulation of Pelvic Nerves.

Abstract

By the use of a method which records photographically the activity taking place in each of several regions on the exposed surface of the bladder it is shown that unilateral stimulation of intact pelvic nerves or of their distal cut ends, with or without section of the hypogastric nerves, usually elicited a prompt, vigorous and well sustained contraction of all portions of the detrusor muscle on the corresponding side with a weaker and often slightly delayed response on the opposite side. This would indicate that the distribution of the pelvic nerves from a given side is not limited to that side of the bladder but, innervates a considerable portion of the controlateral muscle as well.
