STUDY OBJECTIVE: To develop a model, including clinical features and ultrasound findings, to predict the need for ureterolysis (i.e., dissection of the ureter) during laparoscopy for endometriosis. DESIGN: A retrospective observational stu…

OBJECTIVE: To evaluate the diagnostic accuracy of transvaginal ultrasound (TVS) in predicting deep endometriosis (DE) following the International Deep Endometriosis Analysis (IDEA) consensus methodology. METHODS: This was an international …

STUDY OBJECTIVE: The aim of this study was to validate temporally and externally the ultrasound-based endometriosis staging system (UBESS) to predict the level of complexity of laparoscopic surgery for endometriosis. DESIGN: A multicenter,…

To evaluate the diagnostic accuracy of transvaginal ultrasound (TVS) to predict overall deep endometriosis (DE) and DE locations by applying the IDEA terminology. This was an international, multicentre prospective diagnostic accuracy study …

OBJECTIVE: It is well-established that there is a strong association between ovarian endometriomas (OE) and deep endometriosis (DE) and rectouterine pouch (RP) obliteration. We aimed to determine the prevalence of DE and RP obliteration in …

BACKGROUND: Ultrasound has been demonstrated to accurately diagnose rectal deep endometriosis (DE) and pouch of Douglas (POD) obliteration. The role of ultrasound in the assessment of patients who have undergone surgery for rectal DE and PO…

Considered an advanced surgical skill, ureterolysis is necessary to ensure safe surgical treatment of endometriosis. The objective of this study was to develop a decision tree model to predict the need for ureterolysis during laparoscopy fo…

Women with infertility are often investigated with saline-infusion sonohysterography and hysterosalpingo-contrast-sonography. The high prevalence of endometriosis in this population also warrants an evaluation with transvaginal ultrasound f…

We aim to evaluate and compare the diagnostic accuracy of deep endometriosis transvaginal ultrasound (DE TVS) in the presence and absence of ovarian endometriomas (OEs). This was a multicentre observational study of prospectively collected …

OBJECTIVES: To investigate the diagnostic accuracy and interobserver agreement among sonologists when assessing offline ultrasound (US) video sets of the "sliding sign" and among gynecologic surgeons when assessing corresponding laparoscopi…

OBJECTIVE: Evaluate whether symptoms and/or transvaginal ultrasound (TVS) 'soft markers' (ovarian immobility and/or site-specific tenderness (SST)) are associated with endometriosis type/location. STUDY DESIGN: Multicenter prospective obse…

STUDY OBJECTIVE: To validate the preoperative ultrasound-based endometriosis staging system (UBESS) for predicting the correct Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) and Australasian Gynaecolo…

OBJECTIVE: Knowledge of rectouterine cul-de-sac state and consistent classification among surgeons are important in the surgical management of women with endometriosis. The objective of this study was to determine the diagnostic accuracy an…

In the preoperative evaluation of patients, a basic pelvic transvaginal ultrasound (TVS) can reliably predict the presence or absence of ovarian endometriomas. The visualisation of an endometrioma and the known association between endometri…

INTRODUCTION: The study aim was to evaluate the transvaginal sonography (TVS) "sliding sign" alone, direct visualization of the bowel with TVS, and the combination of both methods (ie "sliding sign" and direct visualization of the bowel), t…

1. To evaluate the diagnostic accuracy of transvaginal ultrasound (TVS) direct visualisation (DV) of rectal/rectosigmoid (RS) nodules compared to the "sliding sign" (SS) to predict deep infiltrating endometriosis (DIE) of the rectum ® and t…

To develop of a logistic regression model using TVS findings to predict the presence of rectal/rectosigmoid DIE during laparoscopy. Multicentre prospective observational study undertaken between from January 2009 to February 2017 including …

A negative uterine “sliding sign” (i.e. POD obliteration/uterorectal adhesions) is known to be significantly associated with rectal deep infiltrating endometriosis (DIE). We aim to compare the performance of the “sliding sign” alone to dire…

To prospectively validate the recently developed Ultrasound Based Endometriosis Staging System (UBESS). Multicentre study of consecutive women presenting with chronic pelvic pain from July 2013 to December 2015. All women with symptoms of c…

OBJECTIVE: To develop and assess the performance of a preoperative ultrasound-based endometriosis staging system (UBESS) to predict the level of complexity of laparoscopic surgery for endometriosis. METHODS: This was a multicenter prospect…

OBJECTIVES: To examine the association between ovarian immobility and presence of endometriomas and assess the diagnostic accuracy of transvaginal sonographic (TVS) ovarian immobility in the detection of deep infiltrating endometriosis (DIE…

INTRODUCTION: A negative "sliding sign" during transvaginal sonography (TVS) is associated with pouch of Douglas (POD) obliteration at laparoscopy in women with suspected endometriosis. The aim of the current study was to develop and valida…
