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.
膀胱颈对腹内压升高的活动过度是女性压力性尿失禁的原因之一。阴道超声是显示膀胱颈活动过度的可靠且微创的方法。作者研究了50名压力性尿失禁女性和40名无压力性尿失禁病史的女性，测量了膀胱颈到耻骨联合中线的距离（P.V.）以及膀胱压力线与耻骨联合中线之间的角度（A.I.U.）。控尿女性的特征是静息时A.I.U.中位数为70度，平均B.P.为25.6毫米，压力状态下A.I.U.中位数为80度，平均B.P.为20毫米。尿失禁女性的特征是静息时A.I.U.中位数为80度，平均P.V.为22.5毫米，压力状态下A.I.U.中位数为95度，平均P.V.为10毫米。两组之间存在显著差异。作者推荐阴道超声作为研究膀胱颈活动度的可靠、实用、经济且患者可接受的方法。
