Indications for surgical treatment of diseases resulting from dysfunction of the sympathetic nervous system are based on the symptoms produced and the results obtained from interruption of the sympathetic pathways. The symptoms result from abnormal vasomotor stimuli and motor imbalances in the smooth musculature of the colon, sigmoid, rectum, bladder, ureters and uterus. Since afferent sensations of pain travel through fibers that may be of symppathetic origin and these fibers run parallel with the postganglionic fibers to blood vessels and visceral organs, pain also is considered a symptom resulting from dysfunction of the sympathetic nervous system.
