ABSTRACT:
A method and apparatus for pharmacological control of spastic urethral sphincters, particularly in patients with spinal cord injuries, includes a special monopolar electrode
eedle (30) adapted for insertion through a cystoscope (46) in electrical isolation therewith but connection with an electromyograph (12) for precise determination of injection sites so that a toxin, such as botulinum A, can be injected directly into skeletal muscle tissue, rather than connective tissue, to denervate and thus relax the sphincter.
