Purpose This study evaluated the effectiveness and quality of sleep (QoS) in adult patients with nocturnal lower urinary tract symptoms (LUTS) including nocturia and nocturnal polyuria.
Materials and Methods A total of 102 patients with nocturia and daytime LUTS were enrolled in this study. All patients completed a questionnaire that included the International Prostate Symptom Score (IPSS), quality of life score (QoL), overactive bladder questionnaire (OABq), and a sleepiness index. The sleepiness index was measured with the Korean Beck Depression Inventory (K-BDI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Berlin Questionnaire (BQ), and the International Restless Legs Syndrome Study Group (IRLSSG). Statistical analyses included the Student’s t-test and chi-square test. Differences were considered significant at a p-value of less than 0.05.
Results Nocturia during sleep was experienced by 68 (66.7%) out of 102 patients. There was no significant association between the nocturia- and the sleep-related scales, but with multiple regression analysis for sex and age, the K-BDI score (p=0.05), IPSS score (p=0.05), and OABq (p=0.02) were significantly higher in patients who woke up to void during sleep. A total of 57 (55.9%) patients diagnosed with overactive bladder with nocturia had severe daytime sleepiness on the ESS questionnaire (p=0.019) and more urgency symptoms on the IPSS questionnaire (p=0.007).
Conclusions Patients with nocturia had a greater risk of being depressive and felt sleepier during the daytime. LUTS including nocturia and sleep quality closely affected each other. Therefore, clinicians should consider patients’ LUTS and sleep problems or QoS as well to provide more satisfying outcomes.
