Abstract

Voiding dysfunction is one of the commonest problems among the elderly. This study aimed to elucidate the mechanisms behind the diurnal and nocturnal urine output patterns in young and elderly male volunteers. Of particular interest was bladder reservoir function during the day and night. Young males (n=25; median age 25.0 years; range 22-32 years) and elderly males (n=18; median age 61.1 years; range 55-73 years) were included in the study. Their voiding habits were assessed from a 3-day frequency-volume chart (FVC) detailing all fluid intake and urine output. Data on voided volume, voiding frequency, maximum voided volume (MVV) and average voided volume (AVV) were obtained from the FVC. The young males' average fluid intake was significantly higher than that of the elderly males. On average the elderly males had a slightly higher voiding frequency than the young males, although this was not statistically significant. There was no difference between the two groups regarding their AVVs at night (including the first morning void). The MVVs of the young and elderly males were significantly different, whereas the ratio between voided volume and MVV did not differ between the groups. The main finding was that young and elderly male...Continue Reading
