title: [Voiding disturbance in elderly males examined by prostate mass screening. Gunma Urological Oncology Study Group].
abstract: Information about voiding disturbance was obtained from 34,140 elderly males in Gunma Aged Club Association (Q group) through a questionnaire and from 8,129 males by prostate mass screening for prostate disease (MS group) as to: (1) the characteristics of the subjects examined by the mass screening, (2) the relationship between the voiding disturbance and aging and (3) the frequency of voiding disturbance in the normal elderly males. In MS group, the percentage of young subjects, especially less than 60 years old, who complained voiding disturbance was higher than the expected percentage on the assumption that it increases with aging. The percentage of voiding disturbance in these young subjects was also higher than that of males in the same decade in Q group. In their past and present history, the percentage of benign prostatic hypertrophy (BPH) in these young subjects was higher than the expected percentage on the assumption that the incidence of BPH increases with aging. Judging from these results, it was estimated that they were not satisfied with the medical care by which they were treated or were being treated, and they received this mass screening to obtain consultation for their complains. Loss of the force was related with the prostate size estimated by digital rectal examination but not with aging. However, nocturia was well related with aging but not with the prostate size. Hesitancy, strain and dribbling were not apparently related with either the prostate size or aging. It was demonstrated that frequency of nocturia was 0 to 1 in less than 60 years old normal males, 0 to 2 in 60 to 79 years old ones and 0 to 3 in over 80 years old ones. The other symptoms studied in each decade were also analyzed and discussed.
