Electrodiagnosis of striated urethral sphincter dysfunction

In many centers urethral striated sphincter electromyography has become an essential component of urodynamic testing. The urologist who uses this modality of investigation in an attempt to understand the pathophysiology of striated sphincter dysfunction must have some basic knowledge of electromyography. Attempts have been made to provide such basic information, especially relating to the methods of evaluation and interpretation. We also have incorporated our own views based on our experience with more than 200 subjects with neuropathic vesicourethral dysfunctions.
