Micturitional disturbance in human T-lymphotropic virus type-1-associated myelopathy.

We reported the findings of micturitional histories and urodynamic studies in five patients with human T-lymphotropic virus type-1-associated myelopathy. Histories showed that all patients had obstructive as well as irritative micturitional symptoms, and four of their micturitional symptoms appeared from the onset of the disease. Urodynamic studies showed that four of them had residual urine (average 170 ml), all had detrusor hyperreflexia, two had detrusor-sphincter dyssynergia, and none had neurogenic changes in external urethral sphincter electromyography. Our findings of supranuclear type of voiding dysfunctions seemed to be in accordance with the known pathological lesions of this disease.
