[Electrophysiologic diagnosis of neurogenic bladder in children with myelodysplasia].

Ninety-seven children with neurogenic bladder and myelodysplasia were subjected to complex examination. The somatic innervation of the sphincter urethrae externus and sphincter ani muscles was appraised by the method of sacral guided reactions by a CT-01 electromyograph and by an original method consisting in registration of the reflex response of the named anatomical structures according to the fluctuations of the intraurethral and intraanal pressure. It was established that maintained, partly disturbed, and absolutely absent somatic innervation of the sphincters of the bladder and rectum is encountered in patients with myelodysplasia. The more the innervation of the sphincters disturbed is, the more the urinary bladder is excluded from the "accumulation-evacuation" urodynamic cycle and the lesser the probability of disorders of urodynamics of the upper urinary tract is, and vice versa. The obtained information is important in choosing the therapeutic tactics for patients with a neurogenic bladder.
