Is there an association between the length of the second stage of labour and urinary incontinence in multiparous women?

Objectives: It is unclear whether the length of the second stage of labour plays a role in the development of urinary incontinence (UI). This study aimed to investigate the association between the cumulative length of the second stage of labour in multiparous women and UI.

Methods: This was a longitudinal cohort study of women who had undergone three vaginal deliveries (VDs) between 2008 and 2017.
