Relationship between serum estradiol and follicle-stimulating hormone levels and urodynamic results in women with stress urinary incontinence

Introduction and hypothesis: The purpose of the current study was to determine the relationship between the serum estradiol (E2) and follicle-stimulating hormone (FSH) levels and the urodynamic study results in women with stress urinary incontinence (SUI). Methods: Eighty women were selected among patients who underwent urodynamic testing for SUI. Basic demographic features were evaluated and laboratory tests were performed. Multiple linear regression analyses were performed among the serum E2 and FSH levels and urodynamic results. Results: E2 had a negative correlation with the Q-tip test in post-menopause. FSH had positive correlations with the post-void residual volume in the uroflowmetry and the voiding and flow times in the pressure-flow study in all of the patients and a negative correlation with the peak flow rate in the pressure-flow study in pre-menopause. Conclusions: E2 and FSH were associated with urodynamic parameters in female patients with SUI.
