The pathophysiology of stress urinary incontinence (SUI) is multifactorial. The aim of this study was to explore the factor determining the symptom severity of SUI. One hundred twenty-four women with SUI were retrospectively investigated. Clinical data for analyses included demographics, pelvic organ prolapse quantification, SUI severity using a 4-point Likert scale, ultrasound, 1-h pad tests, and urodynamic studies. Data were analyzed using the Spearman's rho test and Kruskal-Wallis test. The symptom severity was not correlated with risk factors of SUI or the morphologic manifestations representing urethral support defect, but was significantly correlated with urine loss on 1-h pad test, Valsalva leak point pressure (VLPP) grading, and maximum urethral closure pressure (MUCP). Women with higher SUI severity had greater urine loss on 1-h pad tests, worse VLPP grading, and lower MUCP. Urethral sphincter function appears to be an important determinant for the symptom severity of SUI.
