BACKGROUND: The relationship between frailty and nocturnal voiding is poorly understood.
AIM: To characterize the association between frailty, as defined by a frailty index (FI) based upon the Canadian Study of Health and Aging (CSHA) criteria, and nocturia, defined by measures of nocturnal urine production.
METHODS: Real-world retrospective analysis of voiding diaries from elderly males with lower urinary tract symptoms (LUTS) at an outpatient urology clinic. Males ≥ 65 years with ≥ 2 nocturnal voids were included. A modified FI was calculated from the LUTS database, which captured 39 variables from the original CSHA FI. Patients were divided into 3 groups by modified FI: low (≤ 0.077) (n = 59), intermediate (> 0.077 and < 0.179) (n = 58), and high (≥ 0.179) (n = 41). Diary parameters were compared using the Kruskal-Wallis test and pairwise comparisons with the Wilcoxon rank-sum test and Bonferroni adjustment.
RESULTS: The high frailty group was characterized by higher nocturnal urine volume (NUV), maximum voided volume (MVV), nocturnal maximum voided volume (NMVV), and nocturnal urine production (NUP). The presence of comorbid diabetes mellitus did not explain this effect.
CONCLUSION: Elderly males seeking treatment for LUTS with a high frailty burden are disproportionately affected by excess nocturnal urine production. Future research on the mechanistic relationship between urine production and functional impairment is warranted.
