Abstract
Birthing mechanics are poorly understood, though many injuries during childbirth are mechanical, like fetal and maternal tissue damage. Several biomechanical simulation models of parturition have been proposed to investigate birth, but many do not include the uterus. Additionally, most solid models rely on segmenting anatomical structures from clinical images to generate patient geometry, which can be time-consuming. This work presents two new parametric solid modeling methods for generating patient-specific, at-term uterine three-dimensional geometry. Building from an established method of modeling the sagittal uterine shape, this work improves the uterine coronal shape, especially where the fetal head joins the lower uterine wall. Solid models of the uterus and cervix were built from five at-term patients' magnetic resonance imaging (MRI) sets. Using anatomy measurements from MRI-segmented models, two parametric models were created-one that employs an averaged coronal uterine shape and one with multiple axial measurements of the coronal uterus. Through finite element analysis, the two new parametric methods were compared to the MRI-segmented high-fidelity method and a previously published elliptical low-fidelity method. A clear improvement in the at-term uterine shape was found using the two new parametric methods, and agreement in principal Lagrange strain directions was observed across all modeling methods. These methods provide an effective and efficient way to generate three-dimensional solid models of patient-specific maternal uterine anatomy, advancing possibilities for future research in computational birthing biomechanics.

Abstract
PURPOSE To compare the image quality of multiplexed sensitivity-encoding diffusion-weighted imaging (MUSE-DWI) and single-shot echo-planar imaging (SS-EPI-DWI) techniques in uterine MRI. METHODS Eighty-eight eligible patients underwent MUSE-DWI and SS-EPI-DWI examinations simultaneously using a 3.0 T MRI system. Two radiologists independently performed quantitative and qualitative analysis of the two groups of images using a double-blind method. The weighted Kappa test was used to evaluate the interobserver agreement. Wilcoxon's rank sum test was used for qualitative parameters, and paired t-test was used for quantitative parameters. Spearman rank correlation analysis was used to obtained correlation between pathological results and mean apparent diffusion coefficient (ADC) value. RESULTS The qualitative and quantitative analysis of the images by the two radiologists were in good or excellent agreement, with weighted kappa value ranging from 0.636 to 0.981. The scores of total subjective image quality (15.4 ± 0.99) and signal-to-noise ratio (158.99 ± 60.71) of MUSE-DWI were significantly higher than those of SS-EPI-DWI (12.93 ± 1.62 P < 0.001; 130.23 ± 48.29 P < 0.05). It effectively reduced image distortion and artifact, and had better lesion conspicuity. There was no significant difference in contrast-to-noise ratio score and average ADC values between the two DWI sequences. The average ADC values of the two DWI sequences were highest in the normal uterus group and lowest in the endometrial cancer group, with statistically significant differences among groups (P < 0.01). In addition, the average ADC values of the two DWI sequences were negatively correlated with the type of lesions, decreasing with the malignancy of the lesions (r = -0.805 P < 0.01, r = -0.815 P < 0.01). CONCLUSION Compared to SS-EPI-DWI, MUSE-DWI can significantly reduce distortion, artifacts, and fuzziness in MRI of uterine lesions, which is more conducive to lesion detection.

Abstract
PURPOSE OF REVIEW This article reviews recent advances in ultrasound elastography in diagnosing and evaluating the normal nongravid uterus and the infertile uterus in the gynecologic patient. RECENT FINDINGS Focusing on the most recent primary literature, studies have demonstrated new findings among a breadth of gynecologic clinical settings. Studies in the nongravid uterus have found that menopausal status, age, and menstrual phase have not been associated with changes in uterine tissue stiffness. Focusing on myometrial disease, there have been conflicting data regarding the ability to distinguish uterine fibroids from adenomyosis. One area of expanding research surrounding uterine elastography includes the infertile population, where ongoing studies attempt to provide a predictive model using shear wave elastography (SWE) in patients undergoing in-vitro fertilization. SUMMARY Ultrasound elastography has become an increasingly studied and utilized tool in assessing physiologic and pathologic processes in the field of gynecology. Evaluating tissue stiffness through strain and SWE can serve to improve diagnosis of various uterine and cervical lesions, as well as prognosticate outcomes after fertility treatments. This growing area of research will continue to establish the role and application of ultrasound elastography into clinical practice.

Abstract
PURPOSE The PENTEC (Pediatric Normal Tissue Effects in the Clinic) task force aimed to quantify effects of radiation therapy (RT) dose to the female reproductive organs after treatment for childhood cancer. METHODS AND MATERIALS Relevant studies published 1970 to 2017 were identified systematically through PubMed, Medline, and Cochrane databases with additional articles before 2021 identified by the group. Two large studies reported sufficient data to allow modeling of acute ovarian failure (AOF; loss of function ≤5 year from diagnosis) and premature ovarian insufficiency (POI; loss of function at attained age <40 years) based on maximum dose to least affected ovary. Although normal tissue complication probability modeling was not feasible for the uterus due to limited data, the relationship between ultrasound-measured uterine volume and estimated amount of RT was plotted. Limited data regarding vaginal toxicity were available. RESULTS The risk of AOF increases with RT dose to least affected ovary, alkylating agent cumulative dose (cyclophosphamide equivalent dose [CED] in g/m2), age at RT, and stem cell transplantation: Two Gy to the least affected ovary resulted in AOF risk of 1% to 5% (CED = 0, risk increasing with age), 4% to 7% (CED = 10 g/m2, risk increasing with age), and 6% to 13% (CED = 30 g/m2, risk increasing with age). For patients aged 1 and 20 years at time of RT, AOF risk was ≥50% at doses of 24 Gy and 20 Gy with no alkylating chemotherapy, 22.5 Gy and 17 Gy with intermediate alkylator dose (10 g/m2), and 17 Gy and 13 Gy with high alkylator dose (30 g/m2). Risk of POI increases with survivor (attained) age (rather than age at time of RT), radiation dose to least affected ovary, and alkylator dose. Data review suggested that higher radiation doses to the uterus are associated with uterine toxicity, with uterine size considerably restricted after 12 Gy. Vaginal radiation in children is associated with high toxicity risk, although dose-volume data are not available for quantification. CONCLUSIONS Risk of AOF increases with age at RT, CED exposure, and RT dose; risk of POI likewise increases with RT dose, CED exposure, and survivor age. Both AOF and POI are expected to affect fertility and estrogen production. Data suggest that RT uterine dose >12 Gy may be associated with uterine size restriction. Adult literature suggests that maintaining vaginal dose <5 Gy may limit toxicity. Treatment of life-threatening malignancy remains a priority over reproductive preservation; however, when possible, radiation and surgical techniques should be considered to minimize dose to least affected ovary, uterus, and vagina. Survivors should receive endocrine and gynecologic support; those desiring pregnancy should be counseled early to maximize reproductive options.

Abstract
OBJECTIVE To predict spontaneous preterm birth (sPTB) (labor before 37 weeks of pregnancy) in low-risk singleton pregnancies during the second trimester, using ultrasound markers: uterocervical angle (UCA) and cervical length (CL). METHODS In a prospective observational cohort study, we followed primigravid women with singleton pregnancies without known risk factors for sPTB from 16+0-23+6 weeks of pregnancy until birth. Transvaginal ultrasonography on admission revealed the UCA and CL, and maternal history was obtained from submitted patient profiles. Logistic regression models disclosed significant predictive variables, and receiver operating curves (ROCs) demonstrated optimal cut-offs and test accuracy indices. Predictive functions of variables were compared using positive and negative likelihood ratios. RESULTS In a sample of 357 participants, 41 (11.5%) experienced sPTB. UCA and CL were significantly associated with sPTB when adjusting for other variables (adjusted odds ratio: UCA 1.05, 95% confidence interval [CI] 1.02-1.07 and CL 0.82, 95% CI 0.75-0.90). Optimal cut-offs were estimated to be 106° and 33 mm for UCA and CL, respectively. We devised the novel index UCA/CL with an area under the ROC of 0.781 (95% CI 0.734-0.823), cut-off = 3.09°/mm, and improved likelihood ratios (positive: 3.18, 2.47, and 4.22; negative: 0.63, 0.52, and 0.51 for UCA, CL, and UCA/CL, respectively). CONCLUSION The second-trimester UCA/CL was found to be a promising index to predict sPTB in low-risk singleton pregnancies. Further multicenter studies may generalize this conclusion to other gestational ages or risk groups and make it more comprehensive by considering other risk factors.

Abstract
OBJECTIVES We sought to determine the association between intrauterine device (IUD) malposition and previous cesarean delivery (CD) and related uterine anatomical changes. METHODS A retrospective cohort of all persons with an IUD presenting for two- and three-dimensional pelvic ultrasonography over 2 years, for any gynecologic indication, was compiled. IUD malposition was defined as IUD partially or completely positioned outside the endometrial cavity. Uterine position, uterine flexion, and cesarean scar defect (CSD) size were assessed. Patient characteristics and sonographic findings were compared between those with normally positioned and malpositioned IUD. Primary outcome was the rate of IUD malposition in persons with and without a history of CD. Logistic regression analysis was used to control for potential confounders. RESULTS Two hundred ninety-six persons with an IUD had a pelvic ultrasound, 240 (81.1%) had a normally positioned IUD, and 56 (18.9%) had a malpositioned IUD. The most common location of IUD malposition was low uterine segment and cervix (67.9%). Malpositioned IUD was associated with referral for evaluation of pelvic pain (P = .001). Prior CD was significantly associated with a malpositioned IUD, after adjusting for confounders (aOR 3.50, 95% CI 1.31-9.35, P = .01). Among persons with prior CD, uterine retroflexion and a large CSD were independent risk factors for IUD malposition (aOR 4.1, 95% CI 1.1-15.9, P = .04 and aOR 5.4, 95% CI 1.4-20.9, P = .01, respectively). CONCLUSIONS Prior CD is associated with significantly increased risk of IUD malposition. Among persons with previous CD, those with a retroflexed uterus and a large CSD are more likely to have a malpositioned IUD.

Abstract
OBJECTIVE This study aimed to establish the first-ever MRI classification of uterosacral ligament (USL) involvement in deep infiltrating endometriosis (DIE), based on reliable preoperative MRI features correlated with positive predictive values (PPVs) determined through histopathological analysis. METHODS Twenty-two women underwent surgery with histopathology due to symptoms highly suggestive of endometriosis. The 22 preoperative MRIs were analysed retrospectively, blinded to histopathology, and a classification of the preoperative aspect of USLs linked to PPVs was designed. RESULTS According to their aspects, 6 radiological types of USL were identified. The "L-category" corresponded to linear types with regular or irregular margins, including types 1, 2, 3A, and 3B. The "N-category" corresponded to haemorrhagic or nodular types, including types 4, 5A, 5B, and 6. For the L-category, PPVs ranged from 75% to 88%, depending on the USL radiological type. For the N-category, PPVs were 100% for each type. In women with endometriosis symptoms, MRI underestimated USL involvement, especially for type 1. Among the 6 uteri with lateral deviation, only one false-positive result concerning the stretched USL was induced. CONCLUSIONS In women with endometriosis symptoms, our MRI classification identified 2 USL categories, corresponding to 2 kinds of PPV; in these symptomatic patients, a normal MRI does not rule out a DIE diagnosis. ADVANCES IN KNOWLEDGE Our MRI classification of USL involvement in endometriosis may be used as a non-invasive staging of the disease, making it much clearer for clinicians and patients. Hence, we are able to propose a suitable diagnostic and therapeutic procedure for each radiological type.

Abstract
STUDY QUESTION Is morphologic development of the first-trimester utero-placental vasculature associated with embryonic growth and development, fetal growth, and birth weight percentiles? SUMMARY ANSWER Using the utero-placental vascular skeleton (uPVS) as a new imaging marker, this study reveals morphologic development of the first-trimester utero-placental vasculature is positively associated with embryonic growth and development, fetal growth, and birth weight percentiles. WHAT IS KNOWN ALREADY First-trimester development of the utero-placental vasculature is associated with placental function, which subsequently impacts embryonic and fetal ability to reach their full growth potential. The attribution of morphologic variations in the utero-placental vascular development, including the vascular structure and branching density, on prenatal growth remains unknown. STUDY DESIGN, SIZE, DURATION This study was conducted in the VIRTUAL Placental study, a subcohort of 214 ongoing pregnancies, embedded in the prospective observational Rotterdam Periconception Cohort (Predict study). Women were included before 10 weeks gestational age (GA) at a tertiary referral hospital in The Netherlands between January 2017 and March 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS We obtained three-dimensional power Doppler volumes of the gestational sac including the embryo and the placenta at 7, 9, and 11 weeks of gestation. Virtual Reality-based segmentation and a recently developed skeletonization algorithm were applied to the power Doppler volumes to generate the uPVS and to measure utero-placental vascular volume (uPVV). Absolute vascular morphology was quantified by assigning a morphologic characteristic to each voxel in the uPVS (i.e. end-, bifurcation-crossing-, or vessel point). Additionally, total vascular length (mm) was calculated. The ratios of the uPVS characteristics to the uPVV were calculated to determine the density of vascular branching. Embryonic growth was estimated by crown-rump length and embryonic volume. Embryonic development was estimated by Carnegie stages. Fetal growth was measured by estimated fetal weight in the second and third trimester and birth weight percentiles. Linear mixed models were used to estimate trajectories of longitudinal measurements. Linear regression analysis with adjustments for confounders was used to evaluate associations between trajectories of the uPVS and prenatal growth. Groups were stratified for conception method (natural/IVF-ICSI conceptions), fetal sex (male/female), and the occurrence of placenta-related complications (yes/no). MAIN RESULTS AND THE ROLE OF CHANCE Increased absolute vascular morphologic development, estimated by positive random intercepts of the uPVS characteristics, is associated with increased embryonic growth, reflected by crown-rump length (endpoints β = 0.017, 95% CI [0.009; 0.025], bifurcation points β = 0.012, 95% CI [0.006; 0.018], crossing points β = 0.017, 95% CI [0.008; 0.025], vessel points β = 0.01, 95% CI [0.002; 0.008], and total vascular length β = 0.007, 95% CI [0.003; 0.010], and similarly with embryonic volume and Carnegie stage, all P-values ≤ 0.01. Density of vascular branching was negatively associated with estimated fetal weight in the third trimester (endpoints: uPVV β = -94.972, 95% CI [-185.245; -3.698], bifurcation points: uPVV β = -192.601 95% CI [-360.532; -24.670]) and birth weight percentiles (endpoints: uPVV β = -20.727, 95% CI [-32.771; -8.683], bifurcation points: uPVV β -51.097 95% CI [-72.257; -29.937], and crossing points: uPVV β = -48.604 95% CI [-74.246; -22.961])), all P-values < 0.05. After stratification, the associations were observed in natural conceptions specifically. LIMITATION, REASONS FOR CAUTION Although the results of this prospective observational study clearly demonstrate associations between first-trimester utero-placental vascular morphologic development and prenatal growth, further research is required before we can draw firm conclusions about a causal relationship. WIDER IMPLICATIONS OF THE FINDINGS Our findings support the hypothesis that morphologic variations in utero-placental vascular development play a role in the vascular mechanisms involved in embryonic and fetal growth and development. Application of the uPVS could benefit our understanding of the pathophysiology underlying placenta-related complications. Future research should focus on the clinical applicability of the uPVS as an imaging marker for the early detection of fetal growth restriction.

Abstract
PURPOSE The surgical technique for uterine closure following cesarean section influences the healing of the cesarean scar; however, there is still no consensus on the optimal technique regarding the closure of the endometrium layer. The aim of this study was to compare the effect of closure versus non-closure of the endometrium during cesarean section on the risk to develop uterine scar defect and associated symptoms. METHODS A randomized prospective study was conducted of women undergoing first elective cesarean section at a single tertiary medical center. Exclusion criteria included previous uterine scar, preterm delivery and dysmorphic uterus. Women were randomized for endometrial layer closure versus non-closure. Six months following surgery, women were invited to the ambulatory gynecological clinic for follow-up visit. 2-D transvaginal ultrasound examination was performed to evaluate the cesarean scar characteristics. In addition, women were evaluated for symptoms that might be associated with uterine scar defect. Primary outcome was defined as the residual myometrial thickness (RMT) at the uterine cesarean scar. Data are presented as median and interquartile range. RESULTS 130 women were recruited to the study, of them follow-up was achieved in 113 (86.9%). 61 (54%) vs. 52 (46%) of the women were included in the endometrial closure vs. non-closure groups, respectively. Groups were comparable for patient's demographic, clinical characteristics and follow-up time for postoperative evaluation. Median RMT was 5.3 (3.0-7.7) vs. 4.6 (3.0-6.5) mm for the endometrial closure and non-closure groups, respectively (p = 0.38). Substantially low RMT (< 2.5 mm) was measured in four (6.6%) women in the endometrial closure group and three (5.8%) of the women in the non-closure group (p = 0.86). All other uterine scar sonographic measurements, as well as dysmenorrhea, pelvic pain and intermenstrual bleeding rates were comparable between the groups. CONCLUSION Closure versus non-closure of the endometrial layer during cesarean uterine incision repair has no significant difference in cesarean scar characteristics and symptom rates at 6 months follow-up.

Abstract
OBJECTIVE To demonstrate the surgical techniques for improving safety in robotic-assisted abdominal cerclage in patients with bicornuate uteri complicated by recurrent pregnancy loss and cervical insufficiency. DESIGN Stepwise demonstration with narrated video footage. SETTING An academic tertiary care hospital. PATIENTS Our patient is a 22-year-old G2P0020 with a history of recurrent pregnancy loss. During her first pregnancy, she was asymptomatic until 19 weeks and delivered because of a preterm premature rupture of membranes. A transvaginal cerclage was performed for her second pregnancy at 14 weeks, which ended at 16 weeks because of preterm premature rupture of membranes. The final magnetic resonance imaging report noted a "bicorporeal uterus with duplication of the uterine body, resulting in two markedly divergent uterine horns that are fused at the isthmus... unlike a typical didelphic uterus, a single, non septated cervix is noted, which shows normal appearances, measuring 3.8 cm in length." Given her history of a uterine anomaly and recurrent pregnancy loss in the absence of other biochemical factors, her maternal-fetal medicine specialist referred her to us as the patient strongly desired future viable pregnancies. The patient was counseled on multiple alternatives, including different methods of performing the cerclage, and ultimately decided on the robotic-assisted (Da Vinci Xi) prophylactic abdominal cerclage. INTERVENTIONS The bicornuate uterus is a rare class IV mullerian duct anomaly caused by the impaired fusion of the mullerian ducts in the uterus, classically appearing in imaging studies as a heart-shaped uterus. This patient demographic reports a high incidence of obstetric complications. Pregnancy in such a uterus causes complications like first- and second-trimester pregnancy loss, preterm labor, low-birthweight infants, and malpresentation at delivery.1 Researchers have postulated that there is an abnormal ratio of muscle fibers to connective tissue in a congenitally abnormal cervix. During pregnancy, an inadequate uterine volume may lead to increased intrauterine pressure and stress on the lower uterine segment, which can lead to cervical incompetence.2 To address cervical incompetence, cervical cerclages are a commonly utilized procedure, as recent studies demonstrate that the incidence of term pregnancies in the group with documented cervical incompetence treated with cerclage placement increased from 26% to 63%.3 One observational study noted improved obstetrical outcomes occurred with interval placement, a cerclage placed in between pregnancies in the nongravid uterus, compared with cerclage placement between 9 and 10 weeks gestation, with the mean gestational age for delivery at 32.9 weeks and 34.5 weeks when a cerclage was placed in gravid and nongravid women, respectively.4 In addition, another retrospective study was done, which demonstrated a lower incidence of neonatal death with prophylactic cerclages.5 Operating on a nonpregnant uterus offers several benefits, including its reduced size, fewer and smaller blood vessels, and simplified handling. Moreover, there are clearly no concerns regarding the fetus. In the decision to use a robotic-assisted platform vs. laparoscopic, a systematic review showed the rates of third-trimester delivery and live birth (LB) using laparoscopy during pregnancy were found to be 70% and 70%-100%, respectively. The same review demonstrated slightly improved outcomes via the robotic route regarding gestational age at delivery (median, 37 weeks), rates of LB (90%), and third-trimester delivery (90%).6 Additional factors contributing to the preference for robotics in surgical procedures include incorporating advanced tools, which can enhance the robotic system's advantages compared with traditional laparoscopy. An invaluable tool in this context is the simultaneous utilization of Firefly mode, which employs a near-infrared camera system, achieved through injecting indocyanine green dye or integrating other light sources concurrently. The intravenous administration of indocyanine green is acknowledged widely for its safety and efficacy as a contrast agent in the evaluation of microvascular circulation and organ vascularization. This property equips surgeons with heightened precision when guiding the needle, proving especially advantageous when faced with challenges in visualizing vascular anatomy. In our specific case, we harnessed the capabilities of Firefly mode in conjunction with hysteroscopic light, enabling us to vividly illustrate the contours of a bicornuate uterus from both external and internal perspectives. We demonstrate a simplified technique of the abdominal cerclage, one cerclage around the internal cervical os of the uterus, using a robotic-assisted platform in a nongravid patient. The surgery began with the eversion of the umbilicus, and a 15-mm skin incision was made in the umbilicus. A Gelpoint mini advanced access site laparoscopy device was inserted into the incision, and CO2 was allowed to insufflate the abdominal cavity with careful attention given to intraabdominal pressure. Once the DaVinci was docked, the surgeon began the creation of a bladder flap. The bladder was carefully dissected from the lower uterine segment and both uteri using monopolar scissors. The anatomical differences of a bicornuate uterus prompted the surgeon to dissect a wider circumference for safety reasons, where a wider dissection offers a better view of the uterine vessels and ease of introducing the Mersilene tape later on. Bilateral uterine vessels were further skeletonized and exposed anteriorly using blunt dissection and monopolar scissors. After further dissection and lateralization, the final result creates a landmark medial to the right uterine vessels at the level of the internal cervical os with which the needle of the Mersilene tape will be able to pass through. The Mersilene tape was guided from anterior to posterior via a previously straightened needle. Similarly, a landmark was created on the left, and the Mersilene tape was directed from anterior to posterior. The Mersilene tape was placed circumferentially around the internal cervical os of the bicornuate uterus, medial to the uterine vessels. Both ends of the Mersilene tape were then gently pulled, ensuring that the tape was lying flat on the anterior of the internal cervical os with no bowels or uterine vessels within it. The tape was then tied posteriorly at the 6 o'clock position with appropriate tension. A 2-0 silk was then sutured to the tails of the tape using the purse-string technique to ensure that it would remain securely tied and in the correct position. Hemostasis was assured. Both a hysteroscopy and a cystoscopy were done after the completion of the cerclage to ensure that no tape or sutures were seen within the cervical canal or the uterine cavity. None were observed. MAIN OUTCOMES MEASURES The success criteria for the surgery were identified as the patient's ability to attain a viable pregnancy after the cerclage placement, along with achieving LB. RESULTS Subsequently, a spontaneous pregnancy was achieved. An infant weighing 3 pounds and 16 ounces was delivered by cesarean section at 36 weeks because of an oligohydramnios. The infant is currently healthy at 13 pounds. CONCLUSION Robotic-assisted abdominal cerclage around the internal cervical os in a bicornuate uterus offers a possibly feasible and straightforward technique for surgeons seeking to reduce risks, although further research is needed.

Abstract
OBJECTIVE The non-pregnant uterus shows an intrinsic contractility pattern, actively involved in early reproductive processes. Uterine contractility is characterized by endometrial waves that originate from the junctional zone and varies throughout the menstrual cycle due to fluctuations in the concentrations of hormones. The aim of this study was to compare the uterine contractility patterns in the periovulatory phase in a group of patients with isolated adenomyosis and a group of healthy women using transvaginal ultrasound (TVUS). METHODS From March 2019 to March 2021, we enrolled consecutive nulliparous patients in the periovulatory phase of the menstrual cycle, divided in patients with isolated adenomyosis (group A, n = 18) and healthy patients in the control group (group B, n = 18). Patients who met the inclusion criteria underwent TVUS for the study of uterine contractility: the uterus was scanned on sagittal plane for 3 min and all the movies were recorded. Then, static images and video were evaluated offline and the uterine contractility patterns were defined. RESULTS The patients belonging to the study group had a higher incidence of painful symptoms (dysmenorrhea, 6.11 ± 2.81 vs 1.39 ± 2.17; chronic pelvic pain, 2.56 ± 3.01 vs 0.39 ± 1.04) and a larger uterine volume (137.48 ± 117.69 vs 74.50 ± 27.58 cm3; P = 0.04). Regarding the uterine contractility, a statistically significant difference was observed about the retrograde patterns (group A, 27.8% vs group B, 72.2%, P < 0.01) and opposing (group A, 38.9% vs, group B, 5.6%, P = 0.02). CONCLUSION The study confirms the presence of altered uterine peristalsis in the periovulatory phase in patients with adenomyosis. The abnormal uterine peristalsis could lead to both structural and functional changes, which are the basis of the clinical manifestations of adenomyosis and the perpetuation of the anatomical damage.

Abstract
OBJECTIVE To evaluate uterine contractility in patients with adenomyosis compared with healthy controls using a quantitative two-dimensional transvaginal ultrasound (TVUS) speckle tracking method. DESIGN A multicenter prospective observational study took place in three European centers between 2014 and 2023. SETTING One university teaching hospital, 1 teaching hospital and 1 specialised clinic. PATIENTS A total of 46 women with a sonographic or magnetic resonance imaging diagnosis of adenomyosis were included. 106 healthy controls without uterine pathologies were included. INTERVENTION Four-minute TVUS recordings were performed and four uterine contractility features were extracted using a speckle tracking algorithm. MAIN OUTCOMES MEASURES The extracted features were contraction frequency (contractions/min), amplitude, velocity (mm/s), and coordination. Women with adenomyosis were compared with healthy controls according to the phase of the menstrual cycle. RESULTS Throughout the different phases of the menstrual cycle, trends of increased amplitude, decreased frequency and velocity, and reduced contraction coordination were seen in patients with adenomyosis compared with healthy controls. These were statistically significant in the late follicular phase, with a higher amplitude (0.087 ± 0.042 vs. 0.050 ± 0.018), lower frequency and velocity (1.49 ± 0.22 vs. 1.68 ± 0.25 contractions/min, and 0.65 ± 0.18 vs. 0.88 ± 0.29 mm/s, respectively), and reduced contraction coordination (0.34 ± 0.08 vs. 0.26 ± 0.17), in the late luteal phase, with higher amplitude (0.050 ± 0.022 vs. 0.035 ± 0.013), lower velocity (0.51 ± 0.11 vs. 0.65 ± 0.13 mm/s), and reduced contraction coordination (0.027 ± 0.06 vs. 0.18 ± 0.07), and in the midfollicular phase, with decreased frequency (1.48 ± 0.21 vs. 1.69 ± 0.16 contractions/min) in patients with adenomyosis compared with healthy controls. During menses, a higher pain score was significantly associated with lower frequency and velocity and higher contraction amplitude. Results remained significant after correcting for age, parity, and body mass index. CONCLUSION Uterine contractility differs in patients with adenomyosis compared with healthy controls throughout the phases of the menstrual cycle. This suggests an etiologic mechanism for the infertility and dysmenorrhea seen in patients with adenomyosis. Moreover, it presents new potential therapeutic targets and diagnostic markers.

Abstract
An accurate transvaginal ultrasound cervical length is paramount to obtain the best prediction for preterm birth. Transvaginal ultrasound cervical length should be optimally obtained when a lower uterine segment contraction is not seen. For universal transvaginal ultrasound cervical length screening at approximately 20 weeks of gestation, the options are to do the transvaginal ultrasound soon after bladder void (lower uterine segment contractions present in 16%-43% of this approach) or to wait until the end of the anatomy scan (ideally within 30 minutes after bladder voiding) to decrease the chance of a lower uterine segment contraction. If the lower uterine segment contraction persists even after waiting up to 20 minutes or more, only the true transvaginal ultrasound cervical length should be reported. In particular, in patients with a previous spontaneous preterm birth, if the lower uterine segment contraction persists, the transvaginal ultrasound cervical length can be repeated in ≤7 days even in the presence of a normal (>25 mm) cervical length. Similar to a blood pressure cuff that must be of the right size for proper blood pressure measurement and a glucometer that must be properly calibrated, screening with transvaginal ultrasound cervical length should only be performed following a proper and standardized technique, including avoiding as much as feasible the presence of lower uterine segment contractions.

Abstract
A rare case of unicornuate uterus with interstitial ectopic pregnancy was diagnosed using three-dimensional transvaginal ultrasound (3D-TVUS). The ultrasound revealed a "lancet-shaped" endometrial corona, a gestational sac near the uterus base extending toward the uterine serosa, and visible interstitial lines. The patient underwent laparoscopic surgery for a lesion in the right fallopian tube. 3D-TVUS was crucial in precisely locating the gestational sac, aiding in effective treatment. Interstitial ectopic pregnancies risk severe hemorrhaging upon rupture. Rapid, accurate diagnosis is vital for lifesaving treatment and preventing critical complications.

Abstract
OBJECTIVES Timely and accurate preoperative diagnosis of uterine sarcoma will increase patient survival. The primary aim of this study was to describe the ultrasound features of uterine sarcoma compared with those of uterine leiomyoma based on the terms and definitions of the Morphological Uterus Sonographic Assessment (MUSA) group. A secondary aim was to assess the interobserver agreement for reporting on ultrasound features according to MUSA terminology. METHODS This was a retrospective cohort study of patients with uterine sarcoma or uterine leiomyoma treated in a single tertiary center during the periods 1997-2019 and 2016-2019, respectively. Demographic characteristics, presenting symptoms and surgical outcomes were extracted from patients' files. Ultrasound images were re-evaluated independently by two sonologists using MUSA terms and definitions. Descriptive statistics were calculated and interobserver agreement was assessed using Cohen's κ (with squared weights) or intraclass correlation coefficient, as appropriate. RESULTS A total of 107 patients were included, of whom 16 had a uterine sarcoma and 91 had a uterine leiomyoma. Abnormal uterine bleeding was the most frequent presenting symptom (69/107 (64%)). Compared with leiomyoma cases, patients with uterine sarcoma were older (median age, 65 (interquartile range (IQR), 60-70) years vs 48 (IQR, 43-52) years) and more likely to be postmenopausal (13/16 (81%) vs 15/91 (16%)). In the uterine sarcoma cohort, leiomyosarcoma was the most frequent histological type (6/16 (38%)), followed by adenosarcoma (4/16 (25%)). On ultrasound evaluation, according to Observers 1 and 2, the tumor border was irregular in most sarcomas (11/16 (69%) and 13/16 (81%) cases, respectively), but regular in most leiomyomas (65/91 (71%) and 82/91 (90%) cases, respectively). Lesion echogenicity was classified as non-uniform in 68/91 (75%) and 51/91 (56%) leiomyomas by Observers 1 and 2, respectively, and 15/16 (94%) uterine sarcomas by both observers. More than 60% of the uterine sarcomas showed acoustic shadows (11/16 (69%) and 10/16 (63%) cases by Observers 1 and 2, respectively), whereas calcifications were reported in a small minority (0/16 (0%) and 2/16 (13%) cases by Observers 1 and 2, respectively). In uterine sarcomas, intralesional vascularity was reported as moderate to abundant in 13/16 (81%) cases by Observer 1 and 15/16 (94%) cases by Observer 2, while circumferential vascularity was scored as moderate to abundant in 6/16 (38%) by both observers. Interobserver agreement for the presence of cystic areas, calcifications, acoustic shadow, central necrosis, color score (overall, intralesional and circumferential) and maximum diameter of the lesion was moderate. The agreement for shape of lesion, tumor border and echogenicity was fair. CONCLUSIONS A postmenopausal patient presenting with abnormal uterine bleeding and a new or growing mesenchymal mass with irregular tumor borders, moderate-to-abundant intralesional vascularity, cystic areas and an absence of calcifications on ultrasonography is at a higher risk of having a uterine sarcoma. Interobserver agreement for most MUSA terms and definitions is moderate. Future studies should validate the abovementioned clinical and ultrasound findings on uterine mesenchymal tumors in a prospective multicenter fashion. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
BACKGROUND Short-term poor uterine involution manifests as uterine contraction weakness. This is one of the important causes of postpartum hemorrhage, posing a serious threat to the mother's life and safety. The study aims to investigate whether low-intensity focused ultrasound (LIFUS) can effectively shorten lochia duration, alleviate postpartum complications, and accelerate uterine involution compared with the sham treatment. METHODS A multicenter, concealed, randomized, blinded, and sham-controlled clinical trial was conducted across three medical centers involving 176 subjects, utilizing a parallel group design. Enrollment occurred between October 2019 and September 2020, with a 42-day follow-up period. Participants meeting the inclusion and exclusion criteria based on normal prenatal examinations were randomly divided into the LIFUS group or the sham operation group via computer-generated randomization. Patients in the LIFUS group received usual care with the LIFUS protocol, wherein a LIFUS signal was transmitted to the uterine site through coupling gel, or sham treatment, where no low-intensity ultrasound signal output was emitted. The primary outcome, lochia duration, was assessed via weekly telephonic follow-ups post-discharge. The involution of the uterus, measured by uterine fundus height, served as the secondary outcome. RESULTS Among the 256 subjects screened for eligibility, 176 subjects were enrolled and randomly assigned to either the LIFUS group (n = 88) or the Sham group (n = 88). Data on the height of the uterine fundus were obtained from all the patients, with 696 out of 704 measurements (99%) successfully recorded. Overall, a statistically significant difference was noted in time to lochia termination (hazard ratio: 2.65; 95% confidence interval [CI]: 1.82-3.85; P < 0.001). The decline in fundal height exhibited notable discrepancies between the two groups following the second treatment session (mean difference: -1.74; 95% CI: -1.23 to -2.25; P < 0.001) and the third treatment session (mean difference: -3.26; 95% CI: -2.74 to -3.78; P < 0.001) after delivery. None of the subjects had any adverse reactions, such as skin damage or allergies during the treatment. CONCLUSIONS This study found that LIFUS treatment can promote uterine involution and abbreviate the duration of postpartum lochia. Ultrasound emerges as a safe and effective intervention, poised to address further clinical inquiries in the domain of postpartum rehabilitation.

Abstract
BACKGROUND To investigate serum irisin levels in girls at different developmental status and explore the significance of irisin for the diagnosis of central precocious puberty (CPP) in girls. METHODS In this cross-sectional study 111 girls were enrolled, including 43 cases of CPP, 44 cases of peripheral precocious puberty (PPP) and 24 cases of girls with normal sexual development as controls. The data on age, weight and height, measured blood levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol, and irisin were collected. Pelvic Doppler ultrasound was performed to evaluate uterine length, transverse diameter, anteroposterior diameter. The girls were divided into non-CPP group and CPP group according to gonadotropin-releasing hormone (GnRH) stimulation test. RESULTS Serum irisin levels were significantly higher in CPP group than in PPP group and normal control group. Serum irisin level was positively correlated with basal LH level, basal FSH level, peak LH level, peak LH /FSH ratio, uterine volume, bone age, and bone age index. The area under the curve, cut-off value, sensitivity and specificity of serum irisin were 0.958, 219.255 pg/ml, 100% and 80.6%. The combined diagnosis of CPP in girls by serum irisin and serum basal LH combined with uterine volume had an AUC, sensitivity, and specificity of 0.994, 97.6%, and 100%, superior to that of the single index. CONCLUSIONS Serum irisin level in girls with CPP is significantly increased. An irisin combined index could help the diagnosis of CPP in girls.

Abstract
Uterine myomas are the most common pelvic tumors in women, which can lead to abnormal uterine bleeding, abdominal pain, pelvic compression symptoms, infertility, or adverse pregnancy. In this article, we provide a dataset named uterine myoma MRI dataset (UMD), which can be used for clinical research on uterine myoma imaging. The UMD is the largest publicly available uterine MRI dataset to date including 300 cases of uterine myoma T2-weighted imaging (T2WI) sagittal patient images and their corresponding annotation files. The UMD covers 9 types of uterine myomas classified by the International Federation of Obstetrics and Gynecology (FIGO), which were annotated and reviewed by 11 experienced doctors to ensure the authority of the annotated data. The UMD is helpful for uterine myomas classification and uterine 3D reconstruction tasks, which has important implications for clinical research on uterine myomas.

Abstract
INTRODUCTION The management of a pregnancy in a bicornuate uterus is particularly challenging. A bicornuate uterus is a rare occurrence and a twin pregnancy in a bicornuate uterus even more rare. These pregnancies call for intensive diagnostic investigation and interdisciplinary care. CASE PRESENTATION We report on a 27-year-old European woman patient (gravida I, para 0) with a simultaneous pregnancy in each cavity of a bicornuate bicollis uterus after embryo transfer. The condition was confirmed by hysteroscopy and laparoscopy. Several unsuccessful in vitro fertilization (IVF) attempts had been performed earlier before embryo transfer in each cornus. After a physiological course of pregnancy with differential screening at 12 + 6 weeks and 22 + 0 weeks of gestation, the patient presented with therapy-resistant contractions at 27 + 2 weeks. This culminated in the uncomplicated spontaneous delivery of the leading fetus and delayed spontaneous delivery of the second fetus. DISCUSSION Only 16 cases of twin pregnancy in a bicornuate unicollis uterus have been reported worldwide and only 6 in a bicornuate bicollis uterus. The principal risks in such pregnancies are preterm labor, intrauterine growth restriction, malpresentation and preeclampsia. These typical risk factors of a twin pregnancy are greatly potentiated in the above mentioned setting. CONCLUSION A twin pregnancy in the presence of a uterine malformation is rare and difficult to manage. These rare cases must be collected and reported in order to work out algorithms of monitoring and therapy as well as issue appropriate recommendations for their management.

Abstract
BACKGROUND Transverse uterine fundal incision (TUFI) is a beneficial procedure for mothers and babies at risk due to placenta previa-accreta, and has been implemented worldwide. However, the risk of uterine rupture during a subsequent pregnancy remains unclear. We therefore evaluated the TUFI wound scar to determine the approval criteria for pregnancy after this surgery. METHODS Between April 2012 and August 2022, we performed TUFI on 150 women. Among 132 of the 150 women whose uteruses were preserved after TUFI, 84 women wished to conceive again. The wound healing status, scar thickness, and resumption of blood flow were evaluated in these women by magnetic resonance imaging (MRI) and sonohysterogram at 12 months postoperatively. Furthermore, TUFI scars were directly observed during the Cesarean sections in women who subsequently conceived. RESULTS Twelve women were lost to follow-up and one conceived before the evaluation, therefore 71 cases were analyzed. MRI scans revealed that the "scar thickness", the thinnest part of the scar compared with the normal surrounding area, was ≥ 50% in all cases. The TUFI scars were enhanced in dynamic contrast-enhanced MRI except for four women. However, the scar thickness in these four patients was greater than 80%. Twenty-three of the 71 women conceived after TUFI and delivered live babies without notable problems until August 2022. Their MRI scans before pregnancy revealed scar thicknesses of 50-69% in two cases and ≥ 70% in the remaining 21 cases. And resumption of blood flow was confirmed in all patients except two cases whose scar thickness ≥ 90%. No evidence of scar healing failure was detected at subsequent Cesarean sections, but partial thinning was found in two patients whose scar thicknesses were 50-69%. In one woman who conceived seven months after TUFI and before the evaluation, uterine rupture occurred at 26 weeks of gestation. CONCLUSIONS Certain criteria, including an appropriate suture method, delayed conception for at least 12 months, evaluation of the TUFI scar at 12 months postoperatively, and cautious postoperative management, must all be met in order to approve a post-TUFI pregnancy. Possible scar condition criteria for permitting a subsequent pregnancy could include the scar thickness being ≥ 70% of the surrounding area on MRI scans, at least partially resumed blood flow, and no abnormalities on the sonohysterogram.

Abstract
RESEARCH QUESTION Is there a correlation between various morphological parameters of the uterine niche and post-menstrual spotting using three-dimensional models from thin-slice (1 mm) magnetic resonance imaging (MRI)? DESIGN This study retrospectively identified women diagnosed with a symptomatic niche by thin-slice MRI between December 2019 and December 2021. Univariable and multivariable linear regression models assessed the correlations between morphological parameters and the duration post-menstrual spotting. Morphological differences of the niche formed by one versus two Caesarean sections were analysed by univariable and multivariable logistic analysis. RESULTS A total of 205 women diagnosed with symptomatic niche were included in the study. The niche among most women with post-menstrual spotting was ellipsoidal, with width greater than length greater than depth, from which niche volume was estimated based on manual measurements (volume = 0.520 × length × width × depth). Manually calculated niche length (β = 0.257, 95% confidence interval [CI] 0.040-0.473, P = 0.020) and radiomically assessed minor axis length (β = 0.329, 95% CI 0.009-0.795, P = 0.045) both positively correlated with the duration of post-menstrual spotting, whereas the distance between the niche and external os (β = -0.120, 95% CI -0.202 to -0.038, P = 0.004) was inversely correlated. Women with two Cesarean sections reported more days of post-menstrual spotting (8.76 ± 3.54 versus 6.68 ± 3.90 days, P < 0.001) and had increased niche length diameter (adjusted odds ratio [aOR] 1.304, 95% CI 1.190-1.429) and a smaller surface-area-to-volume ratio (aOR 0.296, 95% CI 0.129-0.680). CONCLUSIONS Niche-associated post-menstrual spotting correlates with the length diameter of the niche and the distance between the niche and external os. Niches in women after two Caesarean sections tend to be longer in length diameter and more spherical.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to explore the association between urge urinary incontinence (UUI) and lax uterosacral ligaments (USL) using MRI. METHODS Sixty-seven female participants were recruited prospectively: 41 continent volunteers (control group) and 26 patients with UUI. Static proton density- and T2-weighted turbo spin echo sequences of MR images were used. A radiologist employed a standardized grid system to record structural observations of the USLs on sequentially numbered axial MR images and then applied a four-point grading scale to assess ligament visibility. MR images were interpreted by a radiologist and a urologist, and then validated by an expert radiologist. RESULTS The comparison between the mean length of uterosacral ligaments in the control and UUI groups was highly statistically significant (p < 0.001). The mean length of the right USL was 38 ± 11 mm, and the left USL was 35 ± 12 mm in the UUI group. In the control group, the mean length of the USL was 22 ± 9 mm on the right side and 18 ± 9 mm on the left side, along their craniocaudal extent. The highest inter-observer agreement was on the level of origin and insertion (image numbers), whereas the lowest agreement was on the anatomical site of origin and insertion of the USL in both the control and UUI groups. CONCLUSIONS The average length of USLs in patients with UUI is significantly longer than that in healthy continent women, indicating laxity. Our findings support the relationship between the laxity of the USL and UUI symptoms and have therapeutic implications.

Abstract
Herlyn-Werner-Wunderlich syndrome is an uncommon urogenital anomaly defined by uterus didelphys, obstructed hemi-vagina and unilateral renal anomalies. The most common clinical presentation is dysmenorrhoea following menarche, but it can also present as pain and an abdominal mass. Prader-Willi syndrome is a rare neuroendocrine genetic syndrome. Hypothalamic dysfunction is common and pituitary hormone deficiencies including hypogonadism are prevalent. We report the case of a 33-year-old female with Prader-Willi syndrome who was referred to the Gynaecology clinic due to vaginal bleeding and abdominal pain. Abdominal ultrasound revealed a haematometra and haematocolpos and computed tomography showed a uterus malformation and a right uterine cavity occupation (hematometra) as well as right kidney agenesis. Vaginoscopy and hysteroscopy were performed under general anaesthesia, finding a right bulging vaginal septum and a normal left cervix and hemiuterus. Septotomy was performed with complete haematometrocolpos drainage. The association of the two syndromes remains unclear.

Abstract
OBJECTIVE To evaluate Cesarean scar defects using saline contrast sonohysterography (SCSH) in women with a history of Cesarean scar pregnancy (CSP). METHODS A cohort of 38 non-pregnant women with a history of CSP treated with combined local and systemic methotrexate was investigated prospectively by SCSH. For the purpose of analysis, they were classified, according to the modified Delphi consensus criteria for CSP in early gestation, into three subgroups based on the depth of the gestational sac herniation in the midsagittal plane. Subgroup A included eight (21.1%) cases, in which the largest part of the gestational sac protruded towards the uterine cavity; Subgroup B included 20 (52.6%) cases, in which the largest part of the gestational sac was embedded in the myometrium; and Subgroup C included 10 (26.3%) cases, in which the gestational sac was located partially outside the outer contour of the cervix or uterus. RESULTS SCSH revealed that all women in Subgroup C had a uterine niche. The median niche length (P = 0.006) and depth (P = 0.015) were significantly greater in Subgroup C than in Subgroups A or B. The median residual myometrial thickness (RMT) was significantly lower in Subgroup C than in Subgroups A or B (P = 0.006). CONCLUSIONS Women with prior CSP who had a gestational sac protruding beyond the serosal line had a significantly greater niche length and depth, and lower RMT.

Abstract
OBJECTIVE To compare the performance of the abdominal handheld point-of-care ultrasonography (POCUS) Butterfly-iQ to gold standard transvaginal ultrasonography (US) in identifying the position of intrauterine devices (IUDs) in the hands of a medical doctor specialised in ultrasonography. METHODS In this diagnostic accuracy study, a single operator conducted abdominal POCUS followed by conventional transvaginal US. Seventy patients utilising copper or hormonal IUDs were assessed between June 2021 and October 2022. IUDs were categorised as entirely within the uterine cavity or malpositioned. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated for detecting malpositioned IUDs, with conventional US results serving as the reference standard. Concordance rate and Kappa coefficient were computed to assess the agreement between the two ultrasound modalities. RESULTS Among the 70 patients, 46 (65.7%) used copper IUDs, and 24 (34.3%) used hormonal IUDs. Conventional transvaginal US showed IUDs entirely within the uterine cavity in 56 (80%) patients and 14 (20%) IUDs were malpositioned. Of the 14 malpositioned IUDs seen by conventional US, POCUS identified 13 demonstrating a sensitivity of 92.9% (66.1-99.8). Of the 56 IUDs entirely within the uterine cavity shown by conventional US, only two cases were considered malpositioned by POCUS demonstrating a specificity of 96.4% (87.7-99.6). The concordance rate was 95.7%, and the Kappa value was 0.87 in differentiating between IUDs entirely within the uterine cavity and those that were malpositioned. CONCLUSION Abdominal POCUS using Butterfly-iQ, when administered by an imaging specialist, exhibited excellent performance in confirming IUDs entirely within the uterine cavity.

Abstract
RATIONALE AND OBJECTIVES T2-weighted imaging in at least two orthogonal planes is recommended for assessment of the uterus. To determine whether a convolutional neural network-based algorithm could be used for the re-constructions of uterus axes derived from a 3D SPACE with iterative denoising. MATERIALS AND METHODS 50 patients aged 18-81 (mean: 42) years who underwent an MRI examination of the uterus participated voluntarily in this prospective study after informed consent. In addition to a standard MRI pelvis protocol, a 3D SPACE research application sequence was acquired in sagittal orientation. Reconstructions for both the cervix and the cavum in the short and long axes were performed by a research trainee (T), an experienced radiologist (E), and the prototype software (P). In the next step, the reconstructions were evaluated anonymously by two experienced readers according to 5-point-Likert-Scales. In addition, the length of the cervical canal, the length of the cavum and the distance between the tube angles were measured on all reconstructions. Interobserver agreement was assessed for all ratings. RESULTS For all axes, significant differences were found between the scores of the reconstructions by research T, E and P. P received higher scores and was preferred significantly more often with the exception of the comparison of the reconstruction Cervix short of E (Cervix short: P vs. T: p = 0.02; P vs. E: p = 0.26; Cervix long: P vs. T: p = 0.01; P vs. E: p < 0.01; Cavum short: P vs. T: p = 0.01; P vs. E: p = 0.02; Cavum long: P vs. T: p < 0.01; P vs. E: p < 0.01). Regarding the measured diameters, (length of cervical canal/cavum/distance between tube angles) significantly larger diameters were recorded for P compared to E and T (Cervix long (mm): T: 25.43; E: 25.65; P: 26.65; Cavum short (mm): T: 26.24; E: 25.04; P: 27.33; Cavum long (mm): T: 31.98; E: 32.91; P: 34.41; P vs. T: p < 0.01); P vs. E: p = 0.04). Moderate to substantial agreement was found between Reader 1 and Reader 2 (range: 0.39-0.67). CONCLUSION P was able to reconstruct the axes at least as well as or better than E and T. P could thereby lead to workflow facilitation and enable more efficient reporting of uterine MRI.

Abstract
RATIONALE Uterine rupture is an obstetrical emergency associated with severe maternal and fetal mortality. It is rare in the unscarred uterus of a primipara. PATIENT CONCERNS A 25-year-old woman in her 38th week of gestation presented with slight abdominal pain of sudden onset 10 hours before. An emergency cesarean section was done. After surgery, the patient and the infant survived. DIAGNOSES With slight abdominal pain of clinical signs, ultrasound examination showed that the amniotic sac was found in the peritoneal cavity with a rupture of the uterine fundus. INTERVENTIONS Uterine repair and right salpingectomy. OUTCOMES After surgery, the patient and the infant survived. The newborn weighed 2600 g and had an Apgar score of 10 points per minute. Forty-two days after delivery, the uterus recovered well. LESSONS Spontaneous uterine rupture should be considered in patients even without acute pain, regardless of gestational age, and pregnancy with abdominal cystic mass should consider the possibility of uterine rupture.

Abstract
The objective of this study is to investigate the value of early pregnancy ultrasound combined with ultrasound score (USS) for the evaluation of placenta accreta (PA) in scar uteri. Thirty cases of PA in scar uteri diagnosed by ultrasound at our hospital between June 2021 and June 2022 were selected retrospectively (observation group). In addition, 30 patients had placenta attached to the anterior wall of the uterus and covered the internal orifice of the cervix; however, no PA was selected in the same period (control group). The results of surgical pathology and ultrasound examination in the first trimester of pregnancy (11-14 weeks of pregnancy, fetal top hip length 4.5-8.4 cm) were analyzed. Ultrasonic image characteristics of the 2 groups were scored using an ultrasonic scoring scale. The ultrasonic signs and ultrasonic scores of the 2 groups were analyzed. The diagnostic value of ultrasound and USS for PA in the scarred uterus alone and in combination was analyzed based on the gold standard of surgical and pathological results. The rich blood flow signal at the junction of the uterine serosa and bladder, the rate of blood flow in the cavity of the placental parenchyma, the thinning rate of the myometrium after placenta, and the abnormal rate of the low echo area after placenta in the observation group were significantly higher than those in the control group (P < .05). The USS of the observation group was significantly higher than that of the control group (P < .05). The sensitivity (93.33%) and accuracy (95.00%) of the combined examinations were significantly higher than those of ultrasound (70.00% and 83.33%, respectively) (P < .05). The sensitivity and accuracy of combined examination were slightly higher than those of USS examination (83.33% and 90.00%), but the difference was not statistically significant (P > .05). There was no significant difference between the specificity of combined examination (93.33%) and ultrasound (96.67%) and USS (96.67%) (P > .05). Early pregnancy ultrasound and USS evaluation have high application value in the diagnosis and evaluation of early scar uterine PA. The combination of the 2 methods can further improve the sensitivity and accuracy of diagnosis.

Abstract
OBJECTIVES While the decision of abortion is undeniably complex, there are situations where it becomes a necessary choice. In such circumstances, a secure abortion procedure is essential to safeguard the physical and mental well-being of women. A uterine direct visualization system was designed to fulfill the requirements and this study undertook an assessment of the system's safety and effectiveness within a medical facility setting. MATERIALS AND METHODS Induced abortion requested women in 17 institutions across the country between December 2016 and February 2017 were enrolled. Subjects were separated to the study and control group randomly. Induced abortion was conducted by a uterine direct visualization system and an ultrasound-guided system in the study and control group, respectively. The clinical indexes collected during intra- and post-procedures were analyzed and compared between groups. RESULTS Overall, 392 and 339 subjects were included in the study and control group, respectively. The baseline demographic and clinical characteristics were similar between two groups. Subjects in the study group had significant smaller number of uterine cavity entry (p < 0.001), less 2-h and 14-days postoperative bleeding (all p < 0.001), and less 14-days postoperative abdominal pain (p < 0.001). Significantly higher ratio of normal menstruation, in terms of incidence and duration after 60-days of operation, was observed in the study group (all p < 0.001). CONCLUSIONS Induced abortion with uterine direct visualization system generate better outcome and less complication than the conventional ultrasound-guided abortion procedures.

Abstract
Malignant triton tumor (MTT) is a highly aggressive malignant neoplasm, classified as a variant of malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation. There are few reports that MTT occurred in urogenital system. In the present study, we report the first MTT occurring in the uterus. A 57-year-old woman came to the emergency department due to persistent vaginal bleeding for 2 months. The gynecological palpation found that a club-shaped excrescence existed in the vagina about 7 cm × 3 cm × 3 cm. The mass located in the lower segment of the uterus and the cervix was confirmed by gynecological vaginal ultrasound and magnetic resonance imaging, which was preliminarily diagnosed as cervical carcinoma. After neoplasm punch biopsy, the pathological diagnosis was malignant triton tumor. The patient finally lost follow-up. This is the first report about MTT in the uterus and suggests that pathological biopsy combined with imaging examination is necessary for the diagnosis of rarely MTT.

Abstract
We report a rare case of a retroperitoneal uterus-like mass communicating with the endocervix, which presented as abdominal pain and bloating associated with severe irregular vaginal and postcoital bleeding. Our patient did not have any structural abnormalities of the urogenital system or otherwise, which makes a müllerian defect unlikely in our case. Based on the diagnostic criteria for the choristoma, that theory would be excluded here as the mass communicated with the endocervix. This strengthens the theory of metaplasia, under the effect of oestrogen and accelerated by the hyperoestrogenic state of pregnancy as the most likely postulate for our patient. Although the uterus-like mass is not commonly reported, it should be considered as a possible differential for pelvic masses.

Abstract
OBJECTIVES To use saline infusion sonohysterography (SIS) to evaluate the effect of uterine closure technique on niche formation after multiple cesarean deliveries (CDs). METHODS Patients with at least one prior CD were evaluated for niche via SIS. Subgroups of any number repeat CD (>1 prior), lower-order CD (<4 prior), and higher-order CD (≥4 prior) were analyzed, stratifying by hysterotomy closure technique at last cesarean preceding imaging; techniques included Technique A (endometrium-free double-layer closure) and Technique B (single- or double-layer routine endo-myometrial closure). Niche defects were quantified (depth, length, width, and residual myometrial thickness). The primary outcome was clinically significant niche, defined as depth >2 mm. Statistical analysis was performed using chi-square, ANOVA, t-test, Kruskal-Wallis, and multiple logistic regression, with p-values of <0.05 were statistically significant. RESULTS A total of 172 post-cesarean SIS studies were reviewed: 105 after repeat CDs, 131 after lower-order CDs, and 41 after higher-order CDs. Technique A was associated with a shorter interval to imaging and more double-layer closures. Technique B was associated with more clinically significant niches across all subgroups, and these niches were significantly longer and deeper when present. Multiple logistic regression demonstrated a 5.6, 8.1, and 11-fold increased adjusted odds of clinically significant niche following Technique B closure in the repeat CD (p<0.01), lower-order CD (p<0.001), and higher-order CD (p=0.04) groups, respectively. CONCLUSIONS While multiple CDs are known to increase risk for niche defects and their sequelae, hysterotomy closure technique may help to reduce niche development and severity.

Abstract
High-intensity focused ultrasound (HIFU) has emerged as a promising uterus-sparing and possibly fertility-sparing treatment modality for women with adenomyosis, especially those who desire to conceive. We conducted this systematic review and performed a meta-analysis on clinical studies aimed to improve reproduction in women with adenomyosis. After extensive search of PubMed and CNKI, we identified 10 studies published in English and Chinese involving a total of 557 patients with adenomyosis who desired to conceive after HIFU treatment. We found a pooled estimate of pregnancy rate of 53.4% and of the live birth rate of 35.2%, and there was a substantial heterogeneity among these studies. While there is a potential for HIFU treatment to improve fertility for patients with adenomyosis who desired to conceive, such evidence is very weak as of now. Comparative studies with much higher methodological rigor, preferably randomized clinical trials, are badly needed to further illuminate this issue.

Abstract
Background: Uterine cavity abnormalities contribute to infertility. The purpose of this study was to evaluate the incidence, recurrence rates, and risk factors for uterine cavity abnormalities in women undergoing infertility workup and treatment, focusing on the utility of routinely repeated imaging. Methods: Retrospective cohort study at single academic medical center of 833 infertile women who had uterine cavity evaluations performed at least 9 months apart. Results: Of 833 eligible patients, 664 (79.7%) had normal initial imaging and 169 (20.3%) had abnormal initial imaging. Among the former, 10% had abnormal uterine cavity on repeat saline infusion sonohysterography (SIS); among the latter, 32% had abnormal repeat SIS [Chi-square p < 0.0001, risk ratio 2.30 (95% confidence interval 1.85-2.86)]. On average, 23.1 ± 13.6 months passed between studies. Regardless of initial imaging findings, women with abnormal repeat SIS were older than those with normal repeat SIS, with no difference in time elapsed between studies. There were no associations between repeat imaging outcomes and body mass index, uterine instrumentation, number of treatment cycles, or maximum peak estradiol levels in a single cycle between studies. There was no difference in live birth rate among cycles started within 1 year after repeat SIS across groups. Conclusions: Uterine cavity abnormalities were found in 10% of patients on repeat imaging despite initially normal testing. No risk factors for cavity abnormality on repeat imaging were identified besides age and prior abnormality. It would be prudent to continue performing routine repeat uterine cavity evaluation for women undergoing fertility treatment, particularly if corrective measures had been taken in the past.

Abstract
Objective: To investigate the clinical characteristics, treatments and fertility recovery of rudimentary horn pregnancy (RHP). Methods: The clinical data of 12 cases with RHP diagnosed and treated in Peking University Third Hospital from January 1, 2010 to December 31, 2022 were retrospectively analyzed. Clinical informations, diagnosis and treatments of RHP and the pregnancy status after surgery were analyzed. Results: The median age of 12 RHP patients was 29 years (range: 24-37 years). Eight cases of pregnancy in residual horn of uterus occurred in type Ⅰ residual horn of uterus, 4 cases occurred in type Ⅱ residual horn of uterus; among which 5 cases were misdiagnosed by ultrasound before surgery. All patients underwent excision of residual horn of uterus and affected salpingectomy. After surgery, 9 patients expected future pregnancy, and 3 cases of natural pregnancy, 2 cases of successful pregnancy through assisted reproductive technology. Four pregnancies resulted in live birth with cesarean section, and 1 case resulted in spontaneous abortion during the first trimester of pregnancy. No uterine rupture or ectopic pregnancy occurred in subsequent pregnancies. Conclusions: Ultrasonography could aid early diagnosis of RHP while misdiagnosis occurred in certain cases. Thus, a comprehensive judgment and decision ought to be made based on medical history, physical examination and assisted examination. Surgical exploration is necessary for diagnosis and treatment of RHP. For infertile patients, assisted reproductive technology should be applied when necessary. Caution to prevent the occurrence of pregnancy complications such as uterine rupture, and application of cesarean section to terminate pregnancy are recommended.

Abstract
STUDY QUESTION Do characteristics of the lower uterine segment and cervix modify the risk of preterm delivery in uterus transplant (UTx) recipients? SUMMARY ANSWER The cervical length showed little association with preterm delivery, however, cervical inflammation deserves further exploration as a cause of preterm delivery. WHAT IS KNOWN ALREADY UTx recipients do not have the risk factors normally used to stratify pregnancies that would benefit from cervical length assessment. In addition, unique factors related to absent tissues, a different blood supply, inflammatory processes of rejection, cervical biopsies, and a different microbiome challenge the normal progressive remodeling of the cervix and thus cervical competence. STUDY DESIGN, SIZE, DURATION This is a subanalysis of a clinical trial of 20 women undergoing uterus transplantation at Baylor University Medical Center from 2016 to 2020, in addition to two women who received transplantation outside of a research protocol at our institution through September 2022. In this report, the first 16 UTx recipients that achieved live birth are included. PARTICIPANTS/MATERIALS, SETTING, METHODS The focus of this study was 20 pregnancies that reached the second trimester in 16 women following UTx. We analyzed recipient, transplant, and donor factors to determine if characteristics were associated with delivery outcome. We compared obstetrical outcomes, including planned versus unplanned delivery, by factors such as number of superior venous anastomoses, warm ischemia and cold ischemia times, donor factors including cesarean sections, cervical biopsy results, and cervical ultrasound results. MAIN RESULTS AND THE ROLE OF CHANCE Planned term deliveries occurred in 44% (8/18) of live births. Of the preterm births, 30% (3/10) were planned and 70% (7/10) were unplanned. Unplanned deliveries occurred in women with spontaneous preterm labor, severe rejection, subchorionic hematoma, and placenta previa. Cervical length in UTx recipients averaged 33.5 mm at 24 weeks and 31.5 mm at 28 weeks, comparable to values from the general population. No relationship was seen between delivery outcome and number of veins used, ischemic time, or number of previous cesarean sections. LIMITATIONS, REASONS FOR CAUTION The study's small size allows limited conclusions. The obstetric history of all donors was limited to mode of delivery. WIDER IMPLICATIONS OF THE FINDINGS Cervical length measurements in the UTx population are not expected to deviate from those with a native uterus. While cervical length surveillance remains important, attention must be paid to the results of cervical biopsies which are obtained to monitor rejection. Inflammatory processes seem most predictive of preterm delivery. STUDY FUNDING/COMPETING INTEREST(S) No funding was provided for this study. The authors report no conflicts of interest. TRIAL REGISTRATION NUMBER NCT02656550.

Abstract
Mammalian pregnancy requires gradual yet extreme remodeling of the reproductive organs to support the growth of the embryos and their birth. After delivery, the reproductive organs return to their non-pregnant state. As pregnancy has traditionally been understudied, there are many unknowns pertaining to the mechanisms behind this remarkable remodeling and repair process which, when not successful, can lead to pregnancy-related complications such as maternal trauma, pre-term birth, and pelvic floor disorders. This study presents the first longitudinal imaging data that focuses on revealing anatomical alterations of the vagina, cervix, and uterine horns during pregnancy and postpartum using the mouse model. By utilizing advanced magnetic resonance imaging (MRI) technology, T1-weighted and T2-weighted images of the reproductive organs of three mice in their in vivo environment were collected at five time points: non-pregnant, mid-pregnant (gestation day: 9-10), late pregnant (gestation day: 16-17), postpartum (24-72 h after delivery) and three weeks postpartum. Measurements of the vagina, cervix, and uterine horns were taken by analyzing MRI segmentations of these organs. The cross-sectional diameter, length, and volume of the vagina increased in late pregnancy and then returned to non-pregnant values three weeks after delivery. The cross-sectional diameter of the cervix decreased at mid-pregnancy before increasing in late pregnancy. The volume of the cervix peaked at late pregnancy before shortening by 24-72 h postpartum. As expected, the uterus increased in cross-sectional diameter, length, and volume during pregnancy. The uterine horns decreased in size postpartum, ultimately returning to their average non-pregnant size three weeks postpartum. The newly developed methods for acquiring longitudinal in vivo MRI scans of the murine reproductive system can be extended to future studies that evaluate functional and morphological alterations of this system due to pathologies, interventions, and treatments.

Abstract
BACKGROUND Asymptomatic isthmic contractions are a frequent physiological phenomenon in pregnancy, sometimes triggered by bladder voiding. They can interfere with proper cervical length assessment and may lead to false images of placenta previa. However, there is limited research on the prevalence and characteristics of these contractions. OBJECTIVE This study aimed to determine the prevalence and characteristics of isthmic contractions after bladder voiding in the second trimester of pregnancy, to evaluate their effect on cervical length assessment, and to propose a new method for the objective assessment of the presence and intensity of isthmic contractions. STUDY DESIGN In this prospective observational study, long videos of the uterine cervix were recorded in 30 singleton pregnancies during the second trimester of pregnancy after bladder voiding. Isthmic length and cervicoisthmic length changes were assessed over time. The isthmic length was measured using a new approach, which involved calculating the distance from the base of the cervix to the internal os, including the isthmus. RESULTS Isthmic contractions were observed in 43% of pregnant women (95% confidence interval, 26%-62%) after bladder voiding. The median time for complete isthmus relaxation was 19.7 minutes (95% confidence interval, 15.0 to not available). No substantial differences in maternal characteristics were found between individuals with and without contractions. The proposed method for measuring isthmic length provided an objective assessment of the presence and intensity of isthmic contractions. A cutoff of 18 mm in isthmic length allowed for the distinction of pregnant women presenting a contraction. In addition, the study identified a characteristic undulatory pattern in the relaxation of the isthmus in half of the cases with contractions. CONCLUSION Isthmic contractions are a common occurrence after bladder voiding in the second trimester of pregnancy and may interfere with proper cervical length assessment. We recommend performing cervical assessment at least 20 minutes after bladder voiding to reduce the risk of bias in cervical length measurement and to avoid false images of placenta previa. The new method for measuring isthmic length provides an objective way to assess the presence and intensity of isthmic contractions. Further research is needed to understand the role of isthmic contractions in the physiology of pregnancy and birth.

Abstract
OBJECTIVE Three-dimensional surface rendering of 2-D ultrasound images of the uterus in mapping uterine fibroids is a fast-evolving imaging technique that holds great potential for gynecology. The purpose of this study was to assess the accuracy of 3-D surface rendering of 2-D ultrasound images of the uterus using a new Fibroid Mapping Reviewer Application (FMRA) software for mapping uterine fibroids as compared with the pathological evaluation of uterine fibroids in pre-menopausal women undergoing hysterectomy. METHODS We enrolled women aged 35-55 y scheduled for hysterectomy for symptomatic fibroids at a tertiary care hospital from 2019 to 2021. Per pre-set guidelines, we recorded 2-D images and videos of the uterus with fibroids during the transvaginal ultrasound. The recordings were transferred through USB, loaded in the FMRA software and post-processed to generate a 3-D rendered uterus model. An experienced pathologist assessed and documented the gross examination details per a set protocol. We compared the pre-specified dimensions related to the size (L1, L2) and location (X, Y) of fibroids between the 3-D model and the pathologist's assessment of the hysterectomy specimen. RESULTS A total of 25 fibroids in 25 women, the single largest per woman, were considered for analysis. The two methods had good correlation with respect to size (for L1, R² = 0.9723, and for L2, R² = 0.9784) and location (for X, R² = 0.9618, and for Y, R² = 0.9753). Inter-observer analysis revealed that measurements from two sonologists were reproducible (Cronbach's α = 0.9 for the L1, L2 and L3 dimensions of fibroids from the 3-D model). CONCLUSION The FMRA is a novel tool for mapping fibroids. With its proven accuracy, it will be helpful in planning surgeries and during guided procedures for managing uterine fibroids.

Abstract
BACKGROUND Cotyledonoid dissecting leiomyoma, also named Sternberg tumor, is a rare variant of uterine leiomyoma. The tumor is benign, but the appearance and growth pattern are unusual and alarming. In this article, we report a case of cotyledonoid dissecting leiomyoma in a 55-year-old woman as well as review relevant literature. CASE PRESENTATION We report a case of cotyledonoid dissecting leiomyoma in a 55-year-old Iranian woman who presented with vaginal bleeding 4 months after menopause. Ultrasound showed two heterogeneous hypoechoic masses on the uterine fundus. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed for the patient. Macroscopically, a large heterogeneous intramural mass (140 mm × 120 mm × 120 mm) with a grape-like exophytic mass on the fundus was observed. Her health status was good after surgery, and the patient was discharged from the hospital after 2 days. In a 1-year follow-up period, no recurrence or any other related complications were found. CONCLUSION It is important to recognize this rare variant of leiomyoma to prevent aggressive and inappropriate overdiagnosis and overtreatment. It is suggested to try to use frozen sections for better diagnosis and to preserve fertility in young women suffering from this lesion.

Abstract
Abnormal uterine bleeding (AUB) is defined by the International Federation of Gynecology and Obstetrics as bleeding from the uterine corpus that is abnormal in regularity, volume, frequency, or duration and occurs in the absence of pregnancy. AUB is a common condition that affects about a third of women in their lifetime. Abnormal bleeding in duration, quantity, or timing consists of 2 categories, predictable cyclical heavy menstrual bleeding (HMB) and irregular non-cyclical intermenstrual bleeding (IMB). The most common causes of HMB include fibroids and adenomyosis and IMB is commonly caused by ovulatory dysfunction such as in polycystic ovaries, endometrial polyp, or an IUD. A pelvic ultrasound is the initial and often only imaging modality needed in the imaging evaluation of abnormal uterine bleeding and can accurately identify the common causes of abnormal uterine bleeding in the reproductive age group.

Abstract
Uterine segmentation of endometrial cancer MR images can be a valuable diagnostic tool for gynecologists. However, uterine segmentation based on deep learning relies on artificial pixel-level annotation, which is time-consuming, laborious and subjective. To reduce the dependence on pixel-level annotation, a method of weakly supervised uterine segmentation on endometrial cancer MRI slices is proposed, which only requires scribble label and is enhanced by pseudo-label technology, exponential geodesic distance loss and input disturbance strategy. Specifically, the limitations caused by the shortage of supervision are addressed by dynamically mixing the two outputs of the dual branch network to generate pseudo-labels, expanding supervision information and promoting mutual supervision training. On the other hand, considering the large difference of grayscale intensity between the uterus and surrounding tissues, the exponential geodesic distance loss is introduced to enhance the ability of the network to capture the edge of the uterus. Input disturbance strategies are incorporated to adapt to the flexible and variable characteristics of the uterus and further improve the segmentation performance of the network. The proposed method is evaluated on MRI images from 135 cases of endometrial cancer. Compared with other four weakly supervised segmentation methods, the performance of the proposed method is the best, whose mean DI, HD95, Recall, Precision, ADP are 92.8%, 11.632, 92.7%, 93.6%, 6.5% and increasing by 2.1%, 9.144, 0.6%, 2.4%, 2.9% respectively. The experimental results demonstrate that the proposed method is more effective than other weakly supervised methods and achieves similar performance as those fully supervised.

Abstract
Congenital uterine anomalies have been proven to be associated with impaired reproductive performance. The 2013 ESHRE-ESGE classification of female genital tract malformations defines T shaped and infantalis uterus as dysmorphic uterus. Our aim was to examine whether the reproductive performance of patients with primary congenital dysmorphic uterus can be improved using hysteroscopic metroplasty. A retrospective cohort study of 35 patients suffering from 1 year of failed attempts to conceive, recurrent early pregnancy losses, or repeated implantation failures of in vitro fertilization cycles who were diagnosed with a dysmorphic uterus in both a diagnostic hysteroscopy procedure and three-dimensional transvaginal ultrasound (3D-TVS). All patients had undergone an operative hysteroscopic procedure for uterine anomaly repair and their reproductive performance is described before and after the procedure, so that the women acted as their own control. Within 3 years of the procedure, a total of 25 patients (71.4%) reported that they had achieved a pregnancy. A total of 15% of patients only conceived for the first time after the procedure, 15 patients (42.9%) conceived within 6 months and 18 (51.4%) within 1 year. A total of 12 of the 25 pregnant patients (48%) gave birth to a live newborn. We conclude that in non-DES exposed patients with impaired reproductive performance and congenital dysmorphic uterus, hysteroscopic metroplasty for uterine repair could serve as a treatment option for recurrent implantation failure, and may lead to improved reproductive performance and obstetric outcome.
