Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The knowledge of prevalence and risk factors of nocturnal polyuria might be important for the treatment of women with lower urinary tract symptoms (LUTS). Thus, our aim is to describe the prevalence and risk factors of nocturnal polyuria in women with LUTS.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
