Clinical and urodynamic assessment of nulliparous young women with and without stress incontinence symptoms : a case-control study

Objective: To assess the prevalence of stress urinary incontinence symptoms in young, nulliparous, physically fit women, evaluate their clinical and urodynamic characteristics, and compare them to a matched asymptomatic control group. Methods: All first-year physical education students (N=37) were asked to participate in a four-step study on urinary incontinence. The study included an interview, a clinical examination (incorporating an assessment of pelvic floor muscle strength), ambulatory urodynamics during exercise, and a needle electromyographic assessment of pelvic floor muscles and the striated urethral wall muscle with simultaneous urethral and bladder-pressure measurements
