Selective Percutaneous Sacral Root Blockade with Phenol in Neurovesical Dysfunction

H. D. WESTGATE M.D.1

1 Anesthesiology Department, University of Minnesota Health Sciences Center, Minneapolis, Minnesota

Normal urinary bladder function and micturition are the result of well integrated somatic and visceral nervous activity. Micturition requires complex reciprocal actions between detrusor force and outflow resistance, and abnormalities in this reciprocal activity can be demonstrated by percutaneous stimulation of the sacral roots while simultaneously measuring changes in intravesical pressure. When an abnormal sacral innervation is demonstrated by electrocystometry, selective root blockade with phenol may restore normal bladder function and micturition in some patients. Because of his knowledge of regional anatomy and neurophysiology the anaesthesiologist, acting as a member of a team, can contribute greatly to the overall care of patients with neurovesical dysfunction.
