Cystometry of 15 cases in cervical myelopathy was examined. Mild loss of controll and stress incontinence were complained of only 3 cases but cystometric results were obtained of the unhibited neurogenic bladder in a case and the hypotonic bladder in 5 cases.
It was suggested that the incidence of cervical myelopathy with urinary disturbance contained of subclinical bladder dysfunction was relatively higher.
These 6 patients who revealed bladder dysfunction were more severe than other cases with normal bladder function in neurological impairment but they got improvement postopeaiively of both neurological deficit and bladder dysfunction.
We presume that the presence of urinary disturbance in cervical myelopathy might not be the factor influencing to postoperative results.
