Etiologic Possibilities for Increased Pelvic Floor Electromyography Activity During Cystometry

True detrasor-striated sphincter dyssynergia is seen most characteristically in patients with suprasacral spinal cord transection after a period of spinal shock has passed. Routine cystometry-electromyography records can better define this entity. However, several additional etiologic possibilities may produce cystometry-electromyography records that could be diagnosed erroneously as representing detrusor-sphincter dyssynergia.
