K. Mochida et al., URODYNAMIC AND ELECTROPHYSIOLOGIC STUDY OF THE URINARY DISTURBANCES CAUSED BY CERVICAL MYELOPATHY, Journal of spinal disorders, 9(2), 1996, pp. 141-145
Urinary disturbance is one of the significant symptoms of cervical mye
lopathy. To make the diagnosis of urinary disturbance, preoperative ur
odynamic studies and evoked spinal cord potentials (ESCPs) recording w
ere performed on 60 surgical patients with cervical myelopathy. Half (
30) of this group complained of urinary disturbance, and 22 (37%) were
diagnosed as having neurogenic bladder. The presence of neurogenic bl
adder was closely correlated with severe limb symptoms and relatively
slow ESCP velocity. It was confirmed that neurogenic bladder was cause
d by severe spinal cord damage. However, for 47% of the patients with
urinary complaints, findings of urodynamic examinations were negative;
these patients probably had pathologic or psychosomatic factors other
than neurogenic bladder due to cervical myelopathy. The prognosis of
the neurogenic bladder appears to be influenced by irreversibility of
the spinal cord lesions.
