Lower urinary symptoms associated with HTLV‐1‐associated myelopathy/tropical spastic paraparesis (HAM/TSF) are common, but have been regarded as ‘neurogenic’ due to spinal involvements. However, in some cases, these symptoms are persistent, progressive, and not directly correlated with the severity of other neurologic symptoms of the lower spinal cord. These findings prompted us to locate organic lesions in the lower urinary tract and to correlate them with HTLV‐1 infection. Among 35 HAM patients with lower urinary symptoms, we found 4 cases with the symptoms persistent and progressive: 3 with contracted bladder and another with persistent prostatitis. Histological or cytological examinations indicated local lymphocytic infiltrations in the lower urinary tract in all cases: 3 by the infiltration in the bladder and the other by a high concentration of lymphocytes in expressed prostatic secretions. Of 3 cases whose urinary samples were available, 2 showed significant increase in the concentration of urinary anti‐HTLV‐1 antibody of IgA class. The urinary IgA antibody of the third case was not elevated, but the sample had been obtained after resection of the affected bladder. None of the control cases showed significant anti‐HTLV‐1 IgA antibody in urine except for a case of gross hematuria due to chemotherapy directed against adult T‐cell leukemia. We suggest inclusion of these processes into the spectrum of complications for HAM/TSP. The elevated excretion of anti‐HTLV‐1 of IgA class in urine may be an indicator of these complications.
