This is a multicenter, prospective, randomized comparative study in which patients are randomized to one of four different bladder volumes and a Cough Stress Test (CST) is performed in both the standing and sitting positions. The goal is to assess the agreement of each CST method with both urodynamics diagnosis of Stress Urinary Incontinence (SUI) and the 24-hour pad test. The primary outcome is to determine what CST method best correlated with either test in the diagnosis of SUI.
