Progresses of translabial ultrasound in evaluation of postpartum anal sphincter complex / 中国介入影像与治疗学

ABSTRACT

The injury of anal sphincter complex during childbirth can result in long-term anal incontinence problems.Recently,several new techniques in ultrasound have been used to evaluate the function and injury of anal sphincter,such as tomographic ultrasound imaging,volume contrast imaging and speckle reduction imaging.The diagnosis rate of the injury of anal sphincter complex has been improved rapidly.The development of 2D and 3D ultrasound in evaluating function and injury of postpartum anal sphincter complex were reviewed in this article.
