Fig. 3From: Perineal ultrasound to assess the urethral spatial movement in stress urinary incontinence in womenROC curves (receiver operating curve) analyses of three parameters for predicting stress urinary incontinence by perineal ultrasonography. Point A: the mobility vector distances of A (AMVD); Point B: the mobility vector distances of B (BMVD); RVAδ: the mean variation of retrovesical angle on rest and most effectively ValsalvaBack to article page
