To determine whether levator avulsion is a risk factor for recurrence after cystocele repair.This was an audit of women who underwent anterior colporrhaphy at tertiary hospital between 2002 and 2005, were followed up by interview, clinical examination four-dimensional translabial ultrasound 3-6 years later.Of 242 patients identified through theater records we able to contact 171 (71%). Of 83 agreed attend, 24 (29%) reported symptoms recurrent prolapse. There 33 (40%) cystoceles (ICS POP-Q ≥...
In Brief OBJECTIVE: To estimate changes in levator hiatal dimensions after childbirth women with and without ultrasonographically visible morphological abnormalities of the ani to correlate those delivery mode. METHODS: A total 296 nulliparous were recruited. They examined four-dimensional translabial ultrasonography at 36–38 weeks gestation 3–4 months postpartum. Peripartal correlated data. RESULTS: Mean postpartum follow-up was 5.3 (median 4.1, interquartile range 3.7 5.1). Of 212 who...
To study whether avulsion and ballooning are independent risk factors for symptoms and/or signs of pelvic organ prolapse.Retrospective analysis data obtained in clinical practice.Tertiary urogynecology unit.Seven hundred sixty-one consecutive women with floor dysfunction.Evaluation included history, vaginal examination four-dimensional translabial ultrasound. Ultrasound was performed off-line, blinded against data. Hiatal dimensions were measured at the plane minimal hiatal dimensions....
To determine the prevalence of obstetric anal sphincter injuries (OASIS) in a cohort primiparous women and to evaluate their association with demographic, ultrasound parameters.This was retrospective analysis volume datasets 320 women, acquired at 5 months postpartum. Tomographic imaging (TUI) used external (EAS). A significant EAS defect diagnosed if > 30° seen four or more six TUI slices bracketing EAS.Significant defects were found 69 (27.9% those delivered vaginally). In nine...
Levator avulsion, a common childbirth-related traumatic abnormality of this muscle, is characterized by widened gap between the muscle insertion and urethra. This study assessed use four-dimensional ultrasound imaging to measure levator-urethra (LUG) in order identify avulsion.In retrospective study, we reviewed records 118 women seen for clinical assessment imaging. Axial plane tomographic slices were obtained at intervals 2.5 mm. The distance center urethra levator was measured, blinded...
Tomographic ultrasound imaging has greatly simplified pelvic floor assessment. Abnormalities of the insertion levator ani can be documented in a single frame. In this study we aimed to determine which levels hiatus are associated with alterations parameters organ support.This was subanalysis conducted 296 women seen before and after their first delivery. We analyzed postpartum changes bladder neck descent hiatal area as indicators altered support. examination performed on volumes obtained at...
The levator hiatus is the largest potential hernial portal in human body. Its dimensions are measured axial plane and strongly associated with female pelvic organ prolapse. We aimed to compare two commonly used methods for measuring hiatal dimensions. performed offline analysis of 100 consecutive 4D ultrasound volume datasets women seen a tertiary urogynecological clinic. Hiatal measurements were obtained sectional planes (SP, Method A) rendered volumes 1-2 cm thickness (RV, B). A...
Levator avulsion is common after vaginal delivery and strongly associated with prolapse recurrence. The aim of this study was to compare assessment by digital palpation two ultrasound methods, one using rendered volumes the other multislice imaging, for diagnosis levator avulsion.We retrospectively analyzed randomly identified datasets 266 women seen at a tertiary urogynecology unit. Each patient had undergone an interview, examination 3D/4D translabial examination. Analysis retrieved...
Aims Female pelvic organ prolapse is a common condition. Prolapse recurrence following surgical treatment significant clinical issue. The aim of this study was to determine risk factors for recurrence, attempting improve practice by allowing better patient selection prior surgery. Methods This retrospective utilising records and ultrasound volume imaging data sets obtained in four audits anterior colporrhaphy ± mesh. diagnosed clinically ultrasound; findings were analysed against potential...
To determine the prevalence of evidence residual obstetric anal sphincter injury, to evaluate its association with incontinence (AI) and establish minimal diagnostic criteria for significant (residual) external (EAS) trauma.This was a retrospective analysis ultrasound volume datasets 501 patients attending tertiary urogynecological unit. All underwent standardized interview including determination St Mark's score those presenting AI. Tomographic imaging (TUI) used EAS internal (IAS).Among...
Abstract Objective Urethral mobility is considered an important factor in female urinary incontinence. We therefore undertook a study to correlate segmental urethral mobility, as described by the motion profile (UMP), with symptoms and urodynamic findings. Our null hypothesis was that there would be no statistically significant relationship between incontinence mobility. Methods performed retrospective 198 women who had undergone multichannel testing four‐dimensional translabial ultrasound...
To determine the prevalence of levator ani injury in patients with different types cystocele, as defined by translabial ultrasound, order to shed light on potential pathophysiological mechanisms.The datasets 222 women who had undergone a physical examination, urodynamic testing and four-dimensional (4D) pelvic floor ultrasound were evaluated offline for prolapse, hiatal dimensions trauma using tomographic imaging (TUI), blinded against all clinical data. Cystoceles reaching below symphysis...
