PURPOSE: We objectively investigated the relationship between sleep quality/efficiency and factors associated with micturition using at-home electroencephalogram assessment. MATERIALS AND METHODS: Participants were recruited from among those enrolled in the Fujiwara-kyo Study, a community based longitudinal evaluation that began in Nara Prefecture, Japan, in 2007. Included participants were men at least 65 years old who woke up in the middle of the night/early morning at least 3 times per week with the urge to void. We evaluated lower urinary tract symptoms using the I-PSS and subjective sleep quality using the Pittsburgh Sleep Quality Index. Uroflowmetry and 3-day frequency volume charting measurements were also obtained. Electroencephalogram recordings were obtained during sleep to evaluate objective sleep quality. RESULTS: Final analysis included data from 47 participants. I-PSS-quality of life score and slow wave sleep time were independent predictors of good subjective sleep quality as determined by Pittsburgh Sleep Quality Index scores. Nocturnal urinary volume was an independent predictor of greater sleep efficiency. Maximum flow rate was an independent predictor of longer slow wave sleep time. CONCLUSIONS: In elderly men with nocturia, sleep quality is associated with lower urinary tract function. Higher subjective sleep quality is associated with longer slow wave sleep time and less severe lower urinary tract symptoms. Higher objective sleep quality is further associated with a higher urinary flow rate and lower nocturnal urinary volume.
