Can ballooning of the levator hiatus be determined clinically?
OBJECTIVE The objective of the study was to determine whether genital hiatus (gh) and perineal body (pb), measured using the pelvic organ prolapse quantification system of the International Continence Society, are predictive of an abnormally distensible levator hiatus on ultrasound and of objective prolapse and/or prolapse symptoms. STUDY DESIGN The design of the study included datasets of 18...
متن کاملBiometry of the pubovisceral muscle and levator hiatus by three-dimensional pelvic floor ultrasound.
OBJECTIVE Until recently, magnetic resonance was the only imaging method capable of assessing the levator ani in vivo. Three-dimensional (3D) ultrasound has recently been shown to be able to demonstrate the pubovisceral muscle. The aim of this study was to define the anatomy of the levator hiatus in young nulliparous women with the help of 3D ultrasound. METHODS In a prospective observational...
متن کاملEnlargement of the levator hiatus in female pelvic organ prolapse: cause or effect?
AIM This study was undertaken to investigate whether female pelvic organ prolapse repair changes levator hiatal biometry. METHODS Retrospective analysis of clinical and translabial ultrasound volume data of women who underwent prolapse surgery at a tertiary urogynaecological unit between March 2005 and April 2009. Data sets of 81 women were analysed who had undergone an interview, clinical as...
متن کاملAutomatic segmentation method of pelvic floor levator hiatus in ultrasound using a self-normalizing neural network
Segmentation of the levator hiatus in ultrasound allows the extraction of biometrics, which are of importance for pelvic floor disorder assessment. We present a fully automatic method using a convolutional neural network (CNN) to outline the levator hiatus in a two-dimensional image extracted from a three-dimensional ultrasound volume. In particular, our method uses a recently developed scaled ...
متن کاملHow much does the levator hiatus have to stretch during childbirth?
OBJECTIVE This study was designed to define the degree of stretch/strain required of the levator hiatus in childbirth. There have been attempts at defining the distension required for vaginal childbirth with the help of individual data sets, but from previous work it is clear that hiatal dimensions and distensibility are likely to vary greatly between individuals. DESIGN Retrospective observa...
