Outline of Final Research Achievements

The relationship between urination patterns and diuretics in elderly people requiring nursing care was clarified to obtain suggestions on how to improve nocuturia polyuria. The subjects were elderly people aged 65 and over who had a nocturia index of 33% or more and use a diuretic.
For urination status, urinary incontinence was measured and continuous measurement was performed using an ultrasonic diagnostic imaging system for the bladder. Body water content was investigated using a body water composition meter.
As a result, the amount of urinary incontinence was high until 9 am after the pouring of the diuretic. The amount of urine during the day was less than the amount of water drinked during lunch. Body water content increased most before bedtime. The body water content of the trunk and both legs was lowest at 11:00, which was 5 hours after pouring of the diuretic.

Academic Significance and Societal Importance of the Research Achievements

要介護高齢者の夜間多尿は、頻度が高く尿失禁を伴うことが多い。そのため、睡眠障害やQOLの低下、失禁関連皮膚炎や褥瘡発生に影響し、介護者は夜間のおむつ交換や経済面で負担となっている。利尿剤服用中の夜間多尿の要介護高齢者の排尿パターンを明らかにすることにより、夜間多尿の改善に向けた効果的な利尿剤の内服時間の検討や行動療法の基礎資料となる。
