Influence of Pelvic Floor Muscle Contraction on the Profile of Vaginal Closure Pressure in Continent and Stress Urinary Incontinent Women

Abstract

The results demonstrate that the voluntary pelvic floor muscles impose significant closure forces along the vaginal wall of continent women but not in women with stress urinary incontinence. The implication of these findings is that extrinsic urethral closure pressure is insufficiently augmented by pelvic floor muscle contraction in women with stress urinary incontinence.
