MRI urethrovesical junction mobility is associated with global pelvic floor laxity in female stress incontinence.

Objective: To assess in a population of stress incontinent patients without genital prolapse whether urethrovesical junction mobility is associated with global pelvic floor laxity.

Methods: Dynamic MRI of 40 patients referred prior to surgery for urinary stress incontinence were reviewed retrospectively. The orientation of the urethrovesical junction was evaluated at rest and at straining in reference to the pubococcygeal line, and defined as the bladder neck pubococcygeal angle.
