[Transvaginal echography in the study of urinary stress incontinence].
Hypermobility of the bladder neck in response to increased intraabdominal pressure is one cause of stress urinary incontinence in women. Vaginal ultrasound (u.s.) is reliable and minimally invasive method for demonstrating bladder neck hypermobility. The Authors studied 50 women with S.U.I. and 40 with no history of S.U.I. measuring the distance from the bladder neck to the midline of the symphysis pubis (P.V.) and the angle between the BP line and the midline of the symphysis pubis (A.I.U.). The continent women were characterized by a median A.I.U. of 70 degrees and mean B.P. of 25.6 mm, at rest, a median A.I.U. of 80 degrees and a mean B.P. of 20 mm. at stress. The incontinent women were characterized by a median A.I.U. of 80 degrees and mean P.V. of 22.5 mm. at rest, and a median A.I.U. of 95 degrees and mean P.V. of 10 mm. at stress. There is a significant difference between the two groups. The Authors recommend the vaginal u.s. as reliable, practical, economical and patient accepted method to study the bladder neck mobility.
