Over the last decades, the exact role of the serotonergic system on micturition and urinary continence in women has been investigated and discussed. Traditionally, central serotonergic pathways are considered to have a positive effect on urethral closure mechanism. However, recent clinical trials and experimental animal studies demonstrate conflicting results regarding the effect of serotonergic drugs on urethral pressure (1,2). Furthermore, observational studies suggest that exposure to selective serotonin reuptake inhibitors (SSRI) is associated with a significant increased risk of stress urinary incontinence (SUI) (3). In the light of the extensive use of SSRIs, it is relevant to investigate whether SSRI decreases urethral pressure, which potentially could worsen SUI. The aim of this study was to evaluate the effect of citalopram, a SSRI, on opening urethral pressure (OUP) in women.
