This is a prospective, non-randomized, observational, multicenter study in which urethral length is measured in women with surgically-correctable stress urinary incontinence who undergo a suburethral sling operative procedure. Data will be collected from preoperative urogynecological testing and medical histories. The urethral length will be measured intraoperatively using scaled catheters. Outcome data, including the development of postoperative complications, will be collected at several time intervals.
