RESUMO
AIM: Minimally invasive surgery (MIS) has been introduced as an alternative to more radical surgical procedures. The Japan Society of Gynecologic and Obstetric Endoscopy and Minimally Invasive Therapy conducted a cross-sectional questionnaire survey to ascertain the status of MIS for endometrial cancer. METHODS: The survey was conducted between May 10 and June 30, 2022. The questionnaire included information on personal attributes, academic affiliations, qualifications, hysterectomies, and intraoperative procedures performed. RESULTS: The total number of questionnaire respondents was 436 (9.2% of the membership). The hysterectomy methods and percentage performed were as follows: simple total hysterectomy (equivalent to benign surgery), 3%; simple total hysterectomy with care to avoid shaving the cervix, 31%; extended total hysterectomy, 48%; and modified radical hysterectomy, 15%. An analysis of hysterectomies performed using MIS for endometrial cancer by qualified gynecologists of endoscopy or board-certified gynecologic oncologists showed a tendency not to choose simple total hysterectomy compared to the gynecologists who did not hold certification (p = 0.019, p = 0.045, and p = 0.010, respectively). Additionally, 67% of respondents did not use uterine manipulators, and 59% of the respondents did not perform lymph node dissection following the guidelines for treating endometrial cancer in Japan. CONCLUSION: This study provided the current status of MIS for endometrial cancer in Japan. The hysterectomy method, use of uterine manipulators, and criteria for omitting lymph node dissection were generally in agreement with the guidelines. Currently, an extra-fascial simple hysterectomy, including at least not shaving the cervix, was a major method for early invasive endometrial cancer using MIS.

RESEARCH QUESTION: Would a properly designed educational programme offered to young women improve their awareness and fundamental knowledge of menstrual pain and endometriosis? DESIGN: A multinational cross-sectional study using a pen-and-paper questionnaire among women aged 19-24 years was conducted between 2017 and 2019 to assess fundamental knowledge of menstrual pain and endometriosis. Improvement in knowledge was also analysed using a separate questionnaire completed before, and 1-3 months after, a group discussion, lecture on menstrual pain and endometriosis, or both. RESULTS: Among three groups of students (college [nâ¯=â¯271], medical [nâ¯=â¯877] and nursing [nâ¯=â¯763]), knowledge of menstrual pain and endometriosis was lowest among college students, modest among nursing students and fair among medical students (P < 0.001 for each). The experience of cyclical pain, even when painkillers were taken, was reported by 15.5%, 4.6% and 3.8% of students, respectively. Most students managed their cyclical pain by enduring it or by taking over-the-counter medication. An informative education programme with group discussions, lectures, or both, was successful in improving knowledge and consequences of menstrual pain and endometriosis. Proper education and dissemination of knowledge to college students failed to motivate them to visit gynaecologists; however, medical and nursing students became highly interested in visiting gynaecologists. CONCLUSIONS: An educational programme can improve awareness and knowledge of endometriosis and dysmenorrhoea among young women. The programme motivated nursing and medical students, but not college students, to seek medical attention for early detection and management of endometriosis.

PURPOSE: To collect real-world safety and clinical outcome data on the levonorgestrel-releasing intrauterine system (LNG-IUS) for functional/organic heavy menstrual bleeding (HMB) and dysmenorrhoea in Japanese women (J-MIRAI). MATERIALS AND METHODS: In this prospective, multicentre, single-cohort, open-label, post-authorisation study, we assessed menstrual blood loss after LNG-IUS insertion by changes from baseline in pictorial blood loss assessment chart (PBAC) scores. Scores for the menorrhagia multi-attribute scale (MMAS) were collected for 12 months to assess quality of life. RESULTS: We included 47 patients with complete PBAC score and patient diary data. The median PBAC score before LNG-IUS insertion was 159.0, which decreased significantly to 6.0 at 12 months post-insertion; for patients with adenomyosis (n = 20), PBAC score decreased from 174.5 pre-insertion to 19.5 at 12 months. The number of patient-reported bleeding days was correlated with PBAC score ≥5. The proportion of women with prolonged bleeding decreased from 85.7% to 34.6% by the study's end. Some women reported no bleeding after the first 90-day reference period. The mean MMAS overall score significantly increased from 50.50 before insertion to 88.67 at 12 months. CONCLUSIONS: Japanese women with functional/organic HMB experienced substantial reductions in bleeding symptoms and improvements in quality of life after 12-month use of the LNG-IUS.

This study elucidated the degree of adenomyosis recurrence following gonadotropin-releasing hormone agonist (GnRHa) discontinuation and dienogest efficiency for recurrent adenomyosis. This retrospective cohort study included 30 patients, divided into a group of patients whose progress was observed without providing additional therapy following GnRHa administration for six months (Group G) and a group of patients administered dienogest for six months following six months of GnRHa administration (Group D). Menorrhagia, dysmenorrhea, chronic pelvic pain, abdominal fullness, and uterine volume were recorded prior to treatment, six months after the start of therapy (6 M), and 12 months after the start of therapy (12 M). In Group G (n = 15), although all subjective symptoms disappeared at 6 M, nearly all symptoms recurred at 12 M. Uterine volume significantly decreased from 341.0 cm3 to 156.0 cm3 at 6 M (p = .001) and significantly increased again to 282.3 cm3 at 12 M (p = .003). In Group D (n = 15), all subjective symptoms disappeared at 6 M, and only abdominal fullness returned in a significant number of patients (5 of 5; p = .021) at 12 M. Uterine volume decreased significantly at 6 M (p = .003) and significantly increased again from 162.5 cm3 to 205.6 cm3 at 12 M (p = .006). Subjective symptoms, except for abdominal fullness, did not recur when dienogest was administered after GnRHa.

AIM: To investigate the accuracy and clinical value of an adhesion scoring system using transvaginal ultrasonography for endometriotic adhesion. METHODS: In this prospective observational study, we included 131 patients with endometriosis who underwent surgery. Before surgery, transvaginal ultrasonography and adhesion mapping were performed to determine the presence or absence of adhesions at 10 sites of the pelvis. Mapping accuracy was determined by comparing the mapping findings with the surgical findings. To determine the severity of pelvic adhesions, we developed an adhesion score (0-10). With the adhesion score, we assessed the effect of surgical adhesiolysis and evaluated the relationship between postoperative adhesions and infertility. RESULTS: Of the 10 sites assessed for adhesions, the most frequent site of adhesions was the site between the left ovary and the uterus (70.5%). The overall sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio and accuracy of adhesion mapping were 80.4%, 86.1%, 78.8%, 87.2%, 5.79, 0.23 and 83.9%, respectively. The adhesion score in this system was significantly correlated with the adhesion-related score in the revised American Society for Reproductive Medicine classification (R2 = 0.734). Surgical adhesiolysis yielded only about 30% improvement postoperatively. The adhesion score 1 month after surgery in the non-in vitro fertilization (IVF) pregnancy group was significantly lower than that in the IVF pregnancy group (3.45 vs 5.21; P = 0.02). CONCLUSION: Our adhesion scoring system allowed an accurate prediction of the pelvic adhesion status and may potentially be an indicator of postoperative adhesions and infertility.

We report a rare case of an ovarian steroid cell tumor with a diagnosis prompted by heart failure symptoms. A 28-year-old Japanese nulligravida/nullipara with a chief complaint of respiratory discomfort during physical exertion and exhibiting heart failure symptoms was referred to our hospital. She also had signs of virilization, including secondary menorrhea since the age of 20, hirsutism and balding. Cushing's syndrome was suspected, and further examinations showed hypertestosteronemia and right ovarian tumor. Symptomatic treatment for heart failure with diuretics and antihypertensives was followed by abdominal right adnexectomy performed due to the androgen-producing ovarian tumor. The tumor was solid and larger than a fist, and confirmed as a steroid cell tumor through postoperative histopathology. Serum total testosterone levels normalized at day 3 postoperatively, and menstruation resumed 2 months later. Our case was diagnosed due to heart failure symptoms, and its treatment resulted in improvement in virilization signs.

AIM: Women undergoing infertility treatment often need to balance work and fertility treatment. Therefore, we evaluated the quality of life (QOL) and impact of infertility treatment on Japanese working women and their careers. METHODS: We conducted an online questionnaire at 18 clinics in Japan. Responses were collected from 835 women, 713 of whom were working. The participants were divided into three groups based on treatment stage. Data were collected using the FertiQoL and an original questionnaire created by the authors. The Mann-Whitney U test and a multinomial logistic analysis were used. RESULTS: Approximately 90% of the participants felt that treatment could hinder their work and 8% had quit their jobs. Low QOL was associated with sadness and despair due to infertility and mood disorders, disruptions to life and work, and the complicated medications and procedures involved in treatment. Social isolation and the effect of fertility treatment on daily life and work strongly hindered the careers of working women in the third stage of treatment (in vitro fertilization and intracytoplasmic sperm injection). Approximately 70% of the participants required support to subsidize treatment costs and sought shorter working hours and flextime systems. Only 55% informed their workplaces about the fertility treatment, but about 70% easily gained understanding by informing them. CONCLUSIONS: For many working women, infertility treatment posed barriers to their careers, which could explain the low QOL. Urgent introduction of a support system is necessary in Japan, and understanding and social acceptance of infertility appears to be important.

Genome-wide association studies (GWASs) have discovered numerous single nucleotide polymorphisms (SNPs) associated with human complex disorders. However, functional characterization of the disease-associated SNPs remains a formidable challenge. Here we explored regulatory mechanism of a SNP on chromosome 9p21 associated with endometriosis by leveraging "allele-specific" functional genomic approaches. By re-sequencing 1.29 Mb of 9p21 region and scrutinizing DNase-seq data from the ENCODE project, we prioritized rs17761446 as a candidate functional variant that was in perfect linkage disequilibrium with the original GWAS SNP (rs10965235) and located on DNase I hypersensitive site. Chromosome conformation capture followed by high-throughput sequencing revealed that the protective G allele of rs17761446 exerted stronger chromatin interaction with ANRIL promoter. We demonstrated that the protective allele exhibited preferential binding affinities to TCF7L2 and EP300 by bioinformatics and chromatin immunoprecipitation (ChIP) analyses. ChIP assays for histone H3 lysine 27 acetylation and RNA polymerase II reinforced the enhancer activity of the SNP site. The allele specific expression analysis for eutopic endometrial tissues and endometrial carcinoma cell lines showed that rs17761446 was a cis-regulatory variant where G allele was associated with increased ANRIL expression. Our work illuminates the allelic imbalances in a series of transcriptional regulation from factor binding to gene expression mediated by chromatin interaction underlie the molecular mechanism of 9p21 endometriosis risk locus. Functional genomics on common disease will unlock functional aspect of genotype-phenotype correlations in the post-GWAS stage.

AIM: This study aimed to assess whether hysteroscopic metroplasty using the incision method for septate uterus is a risk factor for adverse obstetric outcomes during pregnancy or delivery. METHODS: This retrospective, single-center cohort study of obstetric complications included 41 patients with recurrent pregnancy loss or unexplained infertility who underwent hysteroscopic metroplasty using the incision method for septate uterus. As controls, we recruited 1139 women who delivered at our hospital during the same period. The primary outcomes were mean weeks of delivery, mean birthweight, rate of cesarean section, rate of breech presentation, rate of post-partum hemorrhage, rate of preterm delivery, rate of placental abruption, rate of placenta previa, rate of placenta accreta and uterine rupture during pregnancy and delivery. RESULTS: The two groups did not differ in terms of age, mean weeks of delivery, mean birthweight, rate of post-partum hemorrhage, rate of preterm delivery, rate of placental abruption, rate of placenta previa or rate of placenta accreta. The rates of cesarean section and breech presentation were significantly higher in the study group than in the control group (56.1 vs 27.7%; P = 0.0002 and 19.5 vs 6.8%; P = 0.007, respectively). There were no cases of uterine rupture during pregnancy or delivery following hysteroscopic metroplasty. CONCLUSION: Hysteroscopic metroplasty using the incision method for septate uterus is not a risk factor for adverse obstetric outcomes. No severe complications, such as placenta abruption, placenta previa, placenta accreta, uterine rupture or heavy hemorrhage, were observed in the postoperative live birth group.

Six years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by The Japan Society of Obstetrics and Gynecology and The Japan Association of Obstetricians and Gynecologists, the third revised edition was published in 2017. The 2017 Guidelines includes 10 additional clinical questions (CQ), which brings the total to 95 CQ (12 on infectious disease, 28 on oncology and benign tumors, 27 on endocrinology and infertility and 28 on healthcare for women). Currently a consensus has been reached on the Guidelines and therefore the objective of this report is to present the general policies regarding diagnostic and treatment methods used in standard gynecological outpatient care that are considered appropriate. At the end of each answer, the corresponding recommendation level (A, B, C) is indicated.

Purpose: A hysteroscopic metroplasty was performed for women with recurrent pregnancy loss owing to a uterine septum, following which some women became infertile. The aim of this study was to elucidate the risk factors of secondary infertility 1 year after hysteroscopic metroplasty for a uterine septum. Methods: A retrospective, single-center, cohort study included women with a history of at least two miscarriages that had been attributed to a uterine septum who underwent a hysteroscopic metroplasty. The patients' background data were compared between the patients who conceived and those who remained infertile at 1 year postoperatively. The data were analyzed by using the Mann-Whitney U-test and multivariate analyses. Results: The postoperative live birth rate was 83.9% (n = 26), with persistent infertility in five women at 1 year. When comparing the pregnancy group with the infertile group, the women in the postoperative infertility group were significantly older than those in the postoperative pregnancy group. The multivariate analysis showed that age was an independent risk factor for persistent infertility. Conclusion: Age was identified as an independent risk factor for postoperative secondary infertility. Therefore, surgery as early as possible is recommended.
RESUMO
AIM: The aim of this study was to assess the cut-off age of the risk factors for postoperative recurrence of ovarian endometriomas and to evaluate the end-points of follow-up after laparoscopic excision of ovarian endometriomas. MATERIAL AND METHODS: We retrospectively reviewed 167 patients who underwent laparoscopic excision of ovarian endometriomas at our hospital between 2000 and 2009, and followed up the patients until 2010. Following surgery, patients chose to receive gonadotrophin-releasing hormone agonist, oral contraceptive pills (OCP), dienogest, or no medication and underwent regular ultrasonographic examinations. Potential risk factors for recurrence, including age at surgery, were assessed in the patients receiving no medication. Postoperative recurrence, defined as re-appearance of an ovarian endometrioma > 2 cm in size, was assessed for each treatment group. RESULTS: Age at surgery was the only significant risk factor for recurrence, at a cut-off of 32 years, obtained through receiver-operator curve analysis. In patients not receiving medication, the recurrence rate gradually increased up to 50% over 5 years; there was no recurrence 5 years after surgery. Although no recurrence was seen in patients during continuous treatment with OCP or dienogest, the disease recurred in 55.5% of patients after discontinuing OCP. CONCLUSIONS: Although adjuvant therapy for all patients may represent overtreatment, the findings of the present study suggest that, in the interest of fertility preservation, continuous postoperative hormonal treatment should be administered, at least to patients younger than 32 years. In patients who decline hormonal treatment, we recommend that they undergo follow-up for recurrence until 5 years after surgery.

PURPOSE: Zygote intrafallopian transfer (ZIFT) is an effective option for patients who have experienced repeated implantation failures (RIF) in assisted reproductive technology (ART) treatment. However, advance planning for the day of the operation can be problematic. Using a hormone replacement cycle (HRC) makes it possible to plan for the day of ZIFT. In the present study, we evaluated whether HRC-ZIFT is useful for RIF patients who have experienced difficulties obtaining morphologically good embryos in vitro. METHODS: A total of 55 patients with a history of five or more unsuccessful transfers received HRC-ZIFT between June 2008 and June 2013. The oocyte pick-ups were performed and the oocytes showing two pronuclei (2PN) were cryopreserved. After receiving more than five 2PN oocytes, the operation day was scheduled in advance, and as a consequence, a HRC was started and ZIFT was performed. The clinical outcomes were evaluated. RESULTS: The average age of the patients was 39.3 years, and the previous OPU and ET attempts numbered 7.5 and 6.9, respectively. The number of previously transferred embryos was 11.8, and the number of morphologically good embryos (MGEs) was only 1.2. The number of transferred 2PN oocytes was 6.7, and the subsequent pregnancy rate was 23.6 %. No ectopic or multiple pregnancies were observed, but there were 6 cases of miscarriage. CONCLUSION: Among RIF patients, in particular those who have difficulty obtaining MGEs in vitro, ZIFT might be a useful option. The HRC allows patients and medical staff to plan for the operation day in advance.

PROBLEM: In women of reproductive age, endometriosis may contribute to dysmenorrhea, chronic pelvic pain, dyspareunia, infertility, adenomyosis, and endometrial ovarian cyst (EOC). Recent studies have shown that chronic inflammation occurs in the pelvis of endometriosis patients and that this inflammation is exacerbated by immunosuppression, leading to survival endometrial debris. However, the detailed immunological mechanisms underlying the aggravation of inflammation and immunosuppression in endometriosis patients remain unclear. METHOD OF STUDY: We investigate the alarmins (high-mobility group box-1, IL-33, IL-1α, and S100B protein), proinflammatory cytokines (IL-6 and IL-1ß), and immune cells (CD8+ T cells, CD4+ T cells, natural killer cells, natural killer T cells, dendritic cells, and macrophages) in peritoneal fluid of patients with EOC using enzyme-linked immunosorbent assay, electrochemiluminescence, and flow cytometry. Then, we analyzed the correlation between these factors and the aggravating indicators of endometriosis, tumor size and revised American Society for Reproductive Medicine (r-ASRM) score. RESULTS: Unexpectedly, there was no correlation between each alarmin level and aggravating indicators. However, the expression of pattern recognition receptors, toll-like receptor 4, and receptor of advanced glycation end-products on macrophages was inversely correlated with aggravating indicators. CONCLUSIONS: The aggravation of endometriosis is associated with a decrease in alarmin receptors but not alarmin levels. Investigation of innate immune systems, such as alarmins and their receptors, may help elucidate new mechanisms of endometriosis.

BACKGROUND: Endometriosis is a multifaceted gynecological condition that poses diagnostic challenges and affects a significant number of women worldwide, leading to pain, infertility, and a reduction in patient quality of life (QoL). Traditional diagnostic methods, such as the revised American Society for Reproductive Medicine (r-ASRM) classification, have limitations, particularly in preoperative settings. The Numerical Multi-Scoring System of Endometriosis (NMS-E) has been proposed to address these shortcomings by providing a comprehensive preoperative diagnostic tool that integrates findings from pelvic examinations and transvaginal ultrasonography. METHODS: This retrospective study aims to validate the effectiveness of the NMS-E in predicting surgical outcomes and correlating with the severity of endometriosis. Data from 111 patients at Nippon Medical School Hospital were analyzed to determine the correlation between NMS-E scores, including E-score-a severity indicator-traditional scoring systems, surgical duration, blood loss, and clinical symptoms. This study also examined the need to refine parameters for deep endometriosis within the NMS-E to enhance its predictive accuracy for disease severity. RESULTS: The mean age of the patient cohort was 35.1 years, with the majority experiencing symptoms such as dysmenorrhea, dyspareunia, and chronic pelvic pain. A statistically significant positive correlation was observed between the NMS-E's E-score and the severity of endometriosis, particularly in predicting surgical duration (Spearman correlation coefficient: 0.724, p < 0.01) and blood loss (coefficient: 0.400, p < 0.01). The NMS-E E-score also correlated strongly with the r-ASRM scores (coefficient: 0.758, p < 0.01), exhibiting a slightly more excellent predictive value for surgical duration than the r-ASRM scores alone. Refinements in the methodology for scoring endometriotic nodules in uterine conditions improved the predictive accuracy for surgical duration (coefficient: 0.752, p < 0.01). CONCLUSIONS: Our findings suggest that the NMS-E represents a valuable preoperative diagnostic tool for endometriosis, effectively correlating with the disease's severity and surgical outcomes. Incorporating the NMS-E into clinical practice could significantly enhance the management of endometriosis by addressing current diagnostic limitations and guiding surgical planning.
RESUMO
Our previous genome-wide association study has demonstrated that single-nucleotide polymorphisms (SNPs) located in intronic and downstream regions of IL1A (interleukin 1α) were associated with the risk of endometriosis. These SNPs on the genome-wide association study platform could be only surrogates for the true causal variant. Thus, we resequenced all the exons of IL1A in 377 patients with endometriosis and 457 healthy controls. We detected seven rare variants (minor allele frequency <0.01) and four common variants. All the rare variants were not associated with endometriosis. The four common variants (rs17561, rs1304037, rs2856836 and rs3783553) in IL1A were significantly associated with endometriosis (P=0.0024, 0.0024, 0.0014 and 0.0061, respectively). All the four SNPs were within a linkage disequilibrium block. Among them, only rs17561 was nonsynonymous (p.A114S), which has been reported to be associated with susceptibility to ovarian cancer. Taken together, we examined association between rs17561 and endometriosis in an independent validation data set (524 patients and 533 healthy controls) replicating significant association (P=4.0 × 10(-5); odds ratio (OR), 1.91; 95% confidence interval (CI), 1.41-2.61). Meta-analysis by combining results from the two stages strengthened the evidence of association (P=2.5 × 10(-7); OR, 1.90; 95% CI, 1.49-2.43). Our findings demonstrated that the nonsynonymous variant of IL1A might confer genetic susceptibility to endometriosis in Japanese population.

Abdominal sacrocolpopexy is the gold standard for treating pelvic organ prolapse (POP) because of safety and durable good results. More recently laparoscopic sacrocolpopexy (LSC), a less invasive approach, has become popular. Although these surgeries are versatile and can treat almost all patients with POP, these techniques have shortcomings. Specifically, reinforcement of lateral vaginal defects are not very strong, thus patients with POP and a severe paravaginal defect are not good candidates for abdominal or laparoscopic sacrocolpopexy. To overcome this problem, we developed a novel type of LSC, which can reinforce severe paravaginal defects by using a reversed T-shaped anterior mesh combining the advantage of transvaginal mesh surgery. We refer to this novel surgery as 'hybrid LSC'. Thus far, eight patients have successfully undergone this surgery. Hybrid LSC is a simple and secure method, and is an alternative treatment for POP with a severe paravaginal defect.

AIM: The aim of this study was to observe the insides of the fallopian tubes of patients with unilateral or bilateral endometriomas by using salpingoscopy and evaluate the inner cavity of the fallopian tubes according to our original scoring system. MATERIAL AND METHODS: From April 2008 through December 2010, patients with unilateral or bilateral endometriomas were recruited (n = 157, endometrioma group). All patients underwent laparoscopic ovarian cystectomy and salpingoscopy. Using salpingoscopy, we observed the tubal lumen and calculated a fallopian tube score (F score) paying attention to the following six results: adhesions, loss of mucosal folds, rounded edges of mucosal folds, debris, foreign bodies, and abnormal vessels. The F scores were compared with those of the unexplained infertility patients who received those same procedures during the same period (n = 235; control group). RESULTS: Slightly more than three-quarters (75.9%) of the patients in the endometrioma group received F scores of 0, and this percentage was significantly higher than that for the control group (139/235 = 59.1%, P < 0.05). The pregnancy rate after conventional treatment for the endometrioma group was 21.7%, and all pregnant patients had achieved an F score of less than 2. CONCLUSION: It is highly possible that infertility patients with ovarian endometriomas are more likely to have intact fallopian tubes, by comparison with infertility patients who do not have ovarian endometriomas.

BACKGROUND: Accurate diagnosis of retroflexed uterus in daily practice is essential because this condition is related to pelvic pain and deep endometriosis. Uterine flexion can be measured by transvaginal ultrasonography (TVUS), a cost-effective primary test, but the accuracy required for diagnosing retroflexed uterus is unclear. This study assessed the accuracy of TVUS for diagnosis of retroflexed uterus in patients with endometriosis and compared it with that of magnetic resonance imaging (MRI) -the gold standard for measuring the uterine axis. METHODS: The study included 123 patients who underwent endometriosis surgery in our department between 2012 and 2017. Uterine flexion angles were measured by retrospectively examining TVUS and MRI images, and the correlation was analyzed. Analysis of anteverted and retroverted uterine subgroups identified aspects of diagnosing uterine flexion with TVUS. RESULTS: Uterine flexion angles on TVUS were strongly positively correlated (r = 0.86) with MRI results. Additionally, TVUS yielded no false-positive diagnoses and 28 false-negative diagnoses of retroflexion. All false-negative diagnoses occurred in patients with anteverted retroflexed uteruses. CONCLUSIONS: TVUS was generally accurate for measuring uterine flexion angle, as indicated by its strong correlation with MRI. Misdiagnosis of anteverted retroflexed uterus was a limitation of using TVUS for retroflexion diagnosis.
