Prevalence and Risk Factor of NP in Women With LUTS

Between September 2010 and January 2019, all women with LUTS visiting urogynecological department of a medical center for urodynamic evaluation were reviewed. Nocturnal polyuria was defined when the proportion of night-time voided volume over 24-hour voided volume was greater than 33% for ≥65 year-old women, and when the proportion of night-time voided volume over 24-hour voided volume was greater than 20% for \<65 year-old women. Backward stepwise multivariable logistic regression analysis was performed using all statistical variables in the univariate logistic regression analysis. P \< 0.05 was considered as statistical significant.
