Abstract
STUDY QUESTION Is there an ideal imaging modality for the detection of uterosacral ligaments/torus uterinus (USL), rectovaginal septum (RVS) and vaginal deep endometriosis (DE) in women with a clinical history of endometriosis? SUMMARY ANSWER The sensitivity for the detection of USL, RVS and vaginal DE using MRI seems to be better than transvaginal ultrasonography (TVS), whilst the specificity of both were excellent. WHAT IS KNOWN ALREADY The surgical management of women with DE can be complex and requires advanced laparoscopic skills with maximal cytoreduction being vital at the first procedure to provide the greatest symptomatic benefit. Owing to a correlation of TVS findings with surgical findings, preoperative imaging has been used to adequately consent women and plan the appropriate surgery. However, until publication of the consensus statement by the International Deep Endometriosis Analysis Group in 2016, there were significant variations within the terms and definitions used to describe DE in the pelvis. STUDY DESIGN SIZE DURATION A systematic review and meta-analysis was conducted using Embase, Google Scholar, Medline, PubMed and Scopus to identify studies published from inception to May 2020, of which only those from 2010 were included owing to the increased proficiency of the sonographers and advancements in technology. PARTICIPANTS/MATERIALS SETTING METHODS All prospective studies that preoperatively assessed any imaging modality for the detection of DE in the USL, RVS and vagina and correlated with the reference standard of surgical data were considered eligible. Study eligibility was restricted to those including a minimum of 10 unaffected and 10 affected participants. MAIN RESULTS AND THE ROLE OF CHANCE There were 1977 references identified from which 10 studies (n = 1188) were included in the final analysis. For the detection of USL DE, the overall pooled sensitivity and specificity for all TVS techniques were 60% (95% CI 32-82%) and 95% (95% CI 90-98%), respectively, and for all MRI techniques were 81% (95% CI 66-90%) and 83% (95% CI 62-94%), respectively. For the detection of RVS DE, the overall pooled sensitivity and specificity for all TVS techniques were 57% (95% CI 30-80%) and 100% (95% CI 92-100%), respectively. For the detection of vaginal DE, the overall pooled sensitivity and specificity for all TVS techniques were 52% (95% CI 29-74%) and 98% (95% CI 95-99%), respectively, and for all MRI techniques were 64% (95% CI 40-83%) and 98% (96% CI 93-99%). Pooled analyses were not possible for other imaging modalities. LIMITATIONS REASONS FOR CAUTION There was a low quality of evidence given the high risk of bias and heterogeneity in the included studies. There are also potential biases secondary to the risk of misdiagnosis at surgery owing to a lack of either histopathological findings or expertise, coupled with the surgeons not being blinded. Furthermore, the varying surgical experience and the lack of clarity regarding complete surgical clearance, thereby also contributing to the lack of histopathology, could also explain the wide range of pre-test probability of disease. WIDER IMPLICATIONS OF THE FINDINGS MRI outperformed TVS for the per-operative diagnosis of USL, RVS and vaginal DE with higher sensitivities, although the specificities for both were excellent. There were improved results with other imaging modalities, such as rectal endoscopy-sonography, as well as the addition of bowel preparation or ultrasound gel to either TVS or MRI, although these are based on individual studies. STUDY FUNDING/COMPETING INTERESTS No funding was received for this study.

Abstract
OBJECTIVES To review the accuracy of different imaging modalities for the detection of rectosigmoid deep endometriosis (DE) in women with clinical suspicion of endometriosis, and to determine the optimal modality. METHODS A search was conducted using PubMed, MEDLINE, Scopus, EMBASE and Google Scholar to identify studies using imaging to evaluate women with suspected DE, published from inception to May 2020. Studies were considered eligible if they were prospective and used any imaging modality to assess preoperatively for the presence of DE in the rectum/rectosigmoid, which was then correlated with the surgical diagnosis as the reference standard. Eligibility was restricted to studies including at least 10 affected and 10 unaffected women. The QUADAS-2 tool was used to assess the quality of the included studies. Mixed-effects diagnostic meta-analysis was used to determine the overall pooled sensitivity and specificity of each imaging modality for rectal/rectosigmoid DE, which were used to calculate the likelihood ratio of a positive (LR+) and negative (LR-) test and diagnostic odds ratio (DOR). RESULTS Of the 1979 records identified, 30 studies (3374 women) were included in the analysis. The overall pooled sensitivity and specificity, LR+, LR- and DOR for the detection of rectal/rectosigmoid DE using transvaginal sonography (TVS) were, respectively, 89% (95% CI, 83-92%), 97% (95% CI, 95-98%), 30.8 (95% CI, 17.6-54.1), 0.12 (95% CI, 0.08-0.17) and 264 (95% CI, 113-614). For magnetic resonance imaging (MRI), the respective values were 86% (95% CI, 79-91%), 96% (95% CI, 94-97%), 21.0 (95% CI, 13.4-33.1), 0.15 (95% CI, 0.09-0.23) and 144 (95% CI, 70-297). For computed tomography, the respective values were 93% (95% CI, 84-97%), 95% (95% CI, 81-99%), 20.3 (95% CI, 4.3-94.9), 0.07 (95% CI, 0.03-0.19) and 280 (95% CI, 28-2826). For rectal endoscopic sonography (RES), the respective values were 92% (95% CI, 87-95%), 98% (95% CI, 96-99%), 37.1 (95% CI, 21.1-65.4), 0.08 (95% CI, 0.05-0.14) and 455 (95% CI, 196-1054). There was significant heterogeneity and the studies were considered methodologically poor according to the QUADAS-2 tool. CONCLUSIONS The sensitivity of TVS for the detection of rectal/rectosigmoid DE seems to be slightly better than that of MRI, although RES was superior to both. The specificity of both TVS and MRI was excellent. As TVS is simpler, faster and more readily available than the other methods, we believe that it should be the first-line diagnostic tool for women with suspected DE. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVE To review the diagnostic accuracy and determine the optimum imaging modality for the detection of bladder deep endometriosis (DE) in women with a clinical suspicion of endometriosis. METHODS A systematic review of studies published from inception to May 2020 using Embase, Google Scholar, Medline, PubMed and Scopus. Prospective studies, which pre-operatively assessed any imaging modality for the presence of bladder DE, and correlated with the gold standard surgical data as a reference were included. The QUADAS-2 tool was used to assess quality. This review was prospectively registered with PROSPERO (CRD42017059872). RESULTS Of the 1,977 references identified, 8 studies (n = 1,052) were included in the analysis. The overall pooled sensitivity and specificity, from which the likelihood ratio of a positive test (LR+), likelihood ratio of a negative test (LR-) and diagnostic odds ratio (DOR) were calculated, for all transvaginal ultrasonography (TVS) techniques were 55 % (95 % CI 28-79%), 99 % (95 % CI 98-100%), 54.5 (95 % CI 18.9-157.4), 0.46 (95 % CI 0.25 - 0.85) and 119 (95 % CI 24-577), and for only two-dimensional (2D) TVS 53 % (95 % CI 23-82%), 99 % (96 % CI 97-100%), 48.8 (95 % CI 13.1-181.4), 0.47 (95 % CI 0.23 - 0.98), and 104 (95 % CI 15-711), respectively. Meta-analyses of the other modalities, namely magnetic resonance imaging (MRI) and transrectal endoscopic sonography (RES), were not possible due to the limited number of studies. There was significant heterogeneity and the studies were considered poor methodologically according to the QUADAS-2 tool. CONCLUSIONS Whilst the sensitivity of TVS was limited, the specificity was excellent. Given that there is a paucity of literature for other imaging modalities, until more studies are performed, TVS should be considered as the first-line tool given it is the only modality with sufficient evidence.

Abstract
OBJECTIVE In light of recent statements from the United States Food and Drug Administration warning against the use of power morcellation of uterine leiomyomas during laparoscopy, we sought to evaluate the use of preoperative two- (2D) and three- (3D) dimensional transvaginal ultrasound (US) assessment of uterine volume to predict the need for morcellation in women undergoing laparoscopic hysterectomy (LH). METHODS This was a prospective observational study performed between October 2008 and November 2011 in a tertiary referral laparoscopic unit. All women scheduled to undergo LH were included and underwent detailed preoperative transvaginal US. Uterine volumes were calculated using 2D-US measurements (ellipsoid formula), and using Virtual Organ Computer-aided AnaLysis (VOCAL™) having acquired 3D-US volumes of the uterus. Age, parity, need to morcellate and final uterine dry weight at histology were recorded. The estimated uterine volumes were then incorporated into a previously published logistic regression model to predict the need to morcellate for both nulliparous and parous women. The probability threshold cut-off of 0.14 (95% sensitivity) was evaluated in terms of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and likelihood ratios (LRs). The performance of the models incorporating 2D- and 3D-US calculations were compared with 2D- and 3D-US-generated volumes alone, using receiver-operating characteristics (ROC) curves. RESULTS Of 76 women who underwent LH during the study period, 79% (n = 60) had complete background and 3D-US data. Their mean age was 43.7 years, 91.7% were parous and 35% underwent morcellation. The greatest uterine volume that did not require morcellation was 404 mL estimated using 3D-US, which corresponded to a uterine volume of 688.8 mL using 2D-US. The smallest uterine volume that required morcellation was 118.9 mL using 3D-US, which corresponded to a uterine volume of 123.4 mL using 2D-US. The 3D-US uterine volume for parous women with a sensitivity of 95% based on ROC-curve analysis was approximately 120 mL, which equated to a predicted probability of morcellation cut-off of 0.14. For this cut-off, specificity was 55.00%, PPV was 51.35%, NPV was 95.65%, LR+ was 2.11 and LR- was 0.09. Areas under the ROC curves for the morcellation logistic regression model were 0.769 (95% CI, 0.653-0.886) and 0.586 (95% CI, 0.419-0.753) using uterine volumes obtained by 3D-US and by 2D-US, respectively, and they were 0.938 (95% CI, 0.879-0.996) and 0.815 (95% CI, 0.681-0.948) using 3D-US and 2D-US volumes alone. CONCLUSIONS The need to morcellate can be predicted preoperatively using 3D-US uterine volumes obtained by transvaginal US with a fair degree of accuracy. Uteri with volumes smaller than 120 mL at 3D-US are very unlikely to require morcellation. The incorporation of 3D-US-estimated uterine volume into the previously published logistic regression model does not seem to confer any significant improvement when compared with 3D-US uterine volume alone to predict the need to morcellate in women undergoing total LH.

Abstract
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). METHODS This was a multicenter prospective observational study of women presenting with chronic pelvic pain from January 2009 to March 2015. Women with or without history of endometriosis who were scheduled to undergo laparoscopic surgery for endometriosis gave a detailed history and underwent specialized TVS in a tertiary referral unit prior to laparoscopy. During TVS, ovarian mobility and the presence of endometriomas were assessed. The relationship between TVS ovarian mobility, with or without endometriomas, and DIE was correlated with the gold standard, diagnosis of endometriosis at laparoscopy. RESULTS Included in the analysis were 265 women with preoperative TVS and laparoscopic outcomes. Ovarian immobility on TVS was significantly associated with presence of endometriomas at surgery, with a prevalence of 12.2%, 10.8% and 52.7% for fixation of the left ovary only, the right ovary only and bilateral ovaries, respectively, compared with 4.2%, 3.7% and 7.3% for normal ovaries. The sensitivity, specificity, positive (PPV) and negative (NPV) predictive values and positive and negative likelihood ratios of TVS ovarian immobility for diagnosis at surgery of immobility of ovaries with endometriomas in the left ovary only were 44.4%, 92.3%, 44.4%, 92.3%, 5.8, 0.6, in the right ovary only were 50.0%, 98.5%, 80.0%, 94.2%, 33.0, 0.5 and bilaterally were 74.4%, 68.6%, 72.5%, 70.6%, 2.4, 0.4, while those for diagnosis of immobility of normal ovaries were 25.0%, 87.9%, 8.3%, 96.4%, 2.1, 0.9 for left ovary only, 14.3%, 92.9%, 7.1%, 96.6%, 2.0, 0.9 for right ovary only and 35.7%, 97.2%, 50.0%, 95.0%, 12.6, 0.7 bilaterally, respectively (P < 0.05 except for normal left and right ovaries with P = 0.2 and 0.4, respectively). The sensitivity, specificity, PPV and NPV for performance of ovarian immobility in the prediction of DIE for all women were 58.3%, 74.1%, 60.6%, 72.2% and in the prediction of need for bowel surgery were 78.2%, 71.1%, 41.3%, 92.6%, respectively. CONCLUSIONS There is a significant association between ovarian immobility and the presence of endometriomas. Ovarian immobility as a sonographic 'soft marker' of DIE performs better in the presence of endometriomas compared with in normal ovaries. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
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 prospective and retrospective cohort study on consecutive women with suspected endometriosis who underwent laparoscopy between June 2009 and July 2013. Each woman underwent a systematic transvaginal ultrasound evaluation to assess the pelvis for different phenotypes of endometriosis, and the diagnostic performance of ultrasound for these different phenotypes was evaluated relative to the gold standard, laparoscopy. A three-stage preoperative UBESS was developed to assess the severity of pelvic endometriosis, based on the histological phenotypes of endometriosis, the anatomical locations of deep infiltrating endometriosis and their sonographic markers of local invasiveness. The three stages of UBESS (I-III) were then correlated with the three levels of complexity of laparoscopic surgery for endometriosis described by the Royal College of Obstetricians and Gynaecologists (Levels 1-3). The end-points were the diagnostic performance of UBESS to predict the level of complexity of laparoscopic surgery for endometriosis, i.e. UBESS stage I to predict Level-1 laparoscopic surgery, UBESS stage II to predict Level-2 laparoscopic surgery and UBESS stage III to predict Level-3 laparoscopic surgery. RESULTS The analysis included 192 women, with a mean ± SD age at diagnosis of endometriosis of 23.7 ± 9.3 years and a mean duration of symptoms prior to presentation of 42 months. Predominant reported locations of pelvic pain were left iliac fossa (32%), right iliac fossa (29.5%) and lower abdomen (61%) and predominant symptoms included dyspareunia (57.5%), dysmenorrhea (58.5%) and dyschezia (41.5%). The accuracy, sensitivity, specificity, positive and negative predictive values and positive and negative likelihood ratios of UBESS I for predicting a requirement for Level-1 laparoscopic surgery were: 87.5%, 83.3%, 91.7%, 90.9%, 84.6%, 10 and 0.182; those of UBESS II for predicting Level-2 surgery were: 87.0%, 73.7%, 90.3%, 65.1%, 93.3%, 7.6 and 0.292; and those of UBESS III for predicting Level-3 surgery were: 95.3%, 94.8%, 95.5%, 90.2%, 97.7%, 21.2 and 0.054, respectively. CONCLUSION UBESS could be utilized to predict the level of complexity of laparoscopic surgery for endometriosis. It has the potential to facilitate the triage of women with suspected endometriosis to the most appropriate surgical expertise required for laparoscopic endometriosis surgery. UBESS needs to be validated externally in multiple centers to assess its general applicability. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVE Vaginal childbirth has a substantial effect on pelvic organ supports, which may be mediated by levator ani (LA) avulsion or hiatal overdistension. Although the impact of a first vaginal delivery on the hiatus has been investigated, little is known about the effect of subsequent births. This study was designed to evaluate the association between vaginal parity and hiatal dimension. DESIGN Retrospective observational study. SETTING A tertiary urogynaecological unit in Australia. POPULATION A total of 780 archived data sets of women seen for symptoms of lower urinary tract and pelvic floor dysfunction. METHODS Standardised in-house interview and assessment using the International Continence Society (ICS) pelvic organ prolapse quantification (POP-Q), and four-dimensional translabial ultrasound. Offline analysis for hiatal dimensions was undertaken blinded to history and clinical examination. MAIN OUTCOME MEASURES Hiatal area on maximum Valsalva. RESULTS Of 780 women, 64 were excluded because of missing ultrasound volumes, leaving 716 for analysis: 96% (n = 686) were parous, with a median parity of three (interquartile range, IQR 2-3), and 91.2% (n = 653) were vaginally parous. Levator avulsion was found in 21% (n = 148). The mean hiatal area on Valsalva was 29 cm(2) (SD 9.4 cm(2) ). On one-way anova, vaginal parity was significantly associated with hiatal area (P < 0.001). Most of the effect seems to occur with the first delivery. Subsequent deliveries do not seem to have any significant effect on hiatal dimensions. This remained true after controlling for potential confounding factors using multivariate regression analysis (P = 0.0123). CONCLUSIONS Vaginal parity was strongly associated with hiatal area on Valsalva. Most of this effect seems to be associated with the first vaginal delivery.

Abstract
Urachal anomalies occur infrequently, but may be associated with morbidity, particularly when the diagnosis has been delayed. We retrospectively reviewed our institution's experience over a 10-year and 7-month period in the investigation and management of suspected urachal anomalies. There were 25 children between November 1995 and June 2006, who presented with a suspected urachal anomaly. The mean age was 12 months (range 3 days to 13 years); 14 were male. Presentations included granulomatous polyp (16), umbilical discharge (4), umbilical sepsis (2) and abdominal pain (2). One case was diagnosed incidentally during a renal ultrasound scan (US). The main investigative tool was US (10), followed by micturating cystourethrogram (2). Of the 25 children, 12 had a patent urachus confirmed by subsequent further imaging or surgery. Our review suggests that whilst clinical examination remains important in the management of a child presenting with a possible urachal pathology, in 36% of the cases the correct diagnosis was only made with further radiological imaging or at operation. Surgical excision was effective with no morbidity or mortality.
