[A questionnaire survey on micturition problems among institutionalized elderly].

Prevalence of micturition problems among 1,023 institutionalized elderly was surveyed by a questionnaire. The reply was obtained from 821 elderly (80.3%) including 276 males and 545 females with ages averaged 77 years (range 61 to 96 years). They had neither highly impaired performance status nor severe dementia. Micturition problems were complained by 38% of male responders, where micturition difficulty was the most common. On the other hand, 23% of female responders answered having micturition problems and urinary frequency was the most common. One hundred and twenty-four of total responders (15%) replied to have urinary incontinence; 8% in men and 19% in women. Over half of patients with marked objective incontinence denied its presence or refused to answer. Seventy-one per cent of the incontinent elderly had no intention to receive medical care. From the above facts, it seems that many elderly have micturition problems and the incidence of urinary incontinence is latently higher than complained at survey.
