The contradictive findings between ultrasound, hysteroscopy and cytokines in women with nonhormonal IUDs suffering from menorrhagia: a prospective study.

PURPOSE: The objective of this study is to assess the correlation between bleeding irregularities and the accurate placement of the intrauterine device (IUD) device in the uterine cavity, determined through transvaginal ultrasonography and hysteroscopy. In addition, the study aims to examine the cytokine profile in the uterine cavity and serum of patients experiencing bleeding irregularities after the insertion of nonhormonal IUDs. METHODS: A prospective cohort study was conducted at a single tertiary medical center, wherein patients experiencing intermenstrual bleeding and spotting after the insertion of nonhormonal IUDs were enrolled. The study involved hysteroscopic and sonographic assessments of the uterine cavity and IUD placement, along with the analysis of blood and uterine cavity cytokine profiles. RESULTS: During the period between July 2019 and February 2020, a total of eight patients who experienced intermenstrual bleeding and spotting after the insertion of nonhormonal IUDs were enrolled the study. One case was excluded since a progestative device was detected by ultrasound. Out of the five cases that underwent a thorough ultrasonographic assessment, three cases (60%) showed an embedded IUD. However, these findings were excluded by the hysteroscopic evaluation. CONCLUSION: The results suggest that ultrasonographic assessment may lead to an overdiagnosis of IUD mispositioning compared to hysteroscopy. In addition, both ultrasound and hysteroscopy have limitations in diagnosing the cause of bleeding in most cases. The role of local reactive inflammatory cytokines should be further studied.

The treatment with Levonorgestrel Releasing Intrauterine System (LNG-IUS) in patients affected by menometrorrhagia, dysmenorrhea and adenomimyois: clinical and ultrasonographic reports.

OBJECTIVE: Adenomyosis is the consequence of the myometrial invasion by endometrial glands and stroma. Transvaginal ultrasonography plays a decisive role in the diagnosis and monitoring of this pathology. Our study aims to evaluate the efficacy of LNG-IUS (Levonorgestrel Releasing Intrauterine System) as medical therapy. We analyzed both clinical symptoms and ultrasonographic aspects of menometrorrhagia and dysmenorrhea in patients with adenomyosis and the control group. PATIENTS AND METHODS: A prospective cohort study was carried out on 28 patients suffering from symptomatic adenomyosis treated with LNG-IUS. Adenomyosis was diagnosed through transvaginal ultrasonography by an expert sonographer. A control group of 27 symptomatic patients (menorrhagia and dysmenorrhea) without a transvaginal ultrasonographic diagnosis of adenomyosis was treated in the same way. The two cohorts were compared to the efficacy of LNG-IUS on menorrhagia and dysmenorrhea.  Patients are evaluated at the time of LNG-IUS insertion and six months after for: increased uterine volume, globulous uterine morphology, uterine symmetry, alterations in the junctional zone, heterogeneous myometrial texture, presence of myometrial cysts, hyperechogenic lines crossing the myometrium, adenomyomas, menstrual blood loss and dysmenorrhea. RESULTS: After six months, the uterine volume decreased significantly in both cohorts (p=0.005; p=0.005). Furthermore, uterine symmetry, visibility of the junctional zone, heterogeneity of myometrial texture, presence of myometrial cysts, hyperechogenic lines and adenomyomas improved in patients affected by adenomyosis (p>0.001; p>0.001; p>0.001; p=0.014; p=0.025; p=0.014). The blood loss decreased significantly in both the cohorts (p<0.001) and particularly in adenomyotic patients. Pain relief was observed in all the patients (p<0.001). CONCLUSIONS: LNG-IUS can be considered an effective treatment for managing symptoms and improving uterine morphology.

Ultrasound assessment of uterine morphology in menorrhagia: case control study.

This was a prospective study to evaluate transvaginal ultrasound measurements in investigating patients with menorrhagia through detailed morphological assessment of the uterus and ovaries by comparing the study group with menorrhagia with a control group with no previous history of menorrhagia. 92 women participated in the study of whom 46 had a history of menorrhagia and 46 were control cases. Mean age of participants was 34.6 years with mean BMI of 27.2. Uterine volume was significantly larger in the index group (p = .024) having reduced uterine mobility (p = .002). 36% of women with menorrhagia were found to have vascular flow within the inner half of the myometrium (p = .002). Women in the study group documented higher pain score both during menstruation and during transvaginal examination compared with controls (p = .008). Uterine fibroids were found in 15% of women with menorrhagia, not significantly more frequently than women without menorrhagia (8.7%) (p = .33).Impact statementWhat is already known on this subject? Transvaginal ultrasound is the non-invasive diagnostic tool of choice in evaluating uterine morphology for menorrhagia in the recognition of the subtle myometrial changes of adenomyosis, fibroids and polyps.What do the results of this study add? Reduced mobility of the uterus against the rectum was more frequent in the study group suggesting the presence of adhesions between the uterus and rectum most likely due to history of endometriosis. Women with menorrhagia had a higher pain score experienced during transvaginal ultrasound as a result of a retroverted and less mobile uterus, hence the movement of the probe against structures which are adherent to each other can cause discomfort during the scan.What are the implications of these findings for clinical practice and/or further research? This study was performed in the hope that the findings obtained will help medical practitioners to provide more accurate information to patients regarding the cause of their menorrhagia, as well as potentially tailoring more specific treatments for menorrhagia based on their ultrasound findings.

Is polycystic ovarian syndrome and insulin resistance associated with abnormal uterine bleeding in adolescents?

OBJECTIVES: The aim of the study was to determine if adolescents with juvenile bleeding had polycystic ovarian syndrome (PCOS) and insulin resistance. MATERIAL AND METHODS: The study was conducted in a group of 43 females aged 12-18 years, diagnosed with juvenile menorrhagia, and 37 healthy female adolescents aged 12-18 years. The study was conducted during the early follicular phase of the menstrual cycle. Menstrual cycle disturbances, acne and hirsutism were recorded. Ultrasound scan determining the condition of the ovaries was conducted. Laboratory tests of the glucose level, cholesterol, LDL and HDL cholesterol and triglycerides fraction, DHEAS, FSH, LH, insulin, SHGB, total testosterone, androstenedione, and free testosterone have been established. RESULTS: The occurrence of regular menstrual cycles (30.23%, p = 0.006) was significantly lower in the juvenile bleeding group. Also, secondary amenorrhea was significantly more likely to be recognized in this group of females (p = 0.03). The concentration of FSH was considerably lower (p = 0.0002) in the group of adolescents with AUB. CONCLUSIONS: Adolescents with abnormal uterine bleeding (AUB) are often diagnosed with secondary amenorrhea, and PCOS. The group with a diagnosis of juvenile bleeding was also diagnosed with higher rates of insulin resistance.

An atypical presentation of an ovarian lymphoma: a case report.

BACKGROUND: Ovarian lymphoma has a varied clinical presentation and rarely presents with heavy menstrual bleeding. It may occur de novo or secondary to systemic disease and macroscopically appear as solid ovarian tumors. CASE PRESENTATION: A 32-year-old Tamil woman presented with heavy menstrual bleeding of 4 months' duration. On examination she was anemic with no lymphadenopathy. A large immobile pelvic mass and three firm nodules were found involving her vaginal walls. Ultrasonography suggested a fibroid uterus with two large pedunculated fibroids. Following preoperative optimization an endometrial sampling and biopsy of the nodules were done. Subsequently, histology revealed proliferative phase endometrium. The vaginal nodules showed lymphoid tissue. She presented a week later with an undulating fever and features of acute abdomen with clinical evidence of ascites. During an emergency laparotomy two large solid ovarian masses, gross ascites, pelvic lymph nodes, para-aortic lymph nodes, mesenteric lymph nodes, omental deposits, and a 24-week-size uterus were found. Bilateral oophorectomy was done. Laboratory investigations revealed raised lactate dehydrogenase with normal serum ß-human chorionic gonadotropin, alpha-fetoprotein, and cancer antigen-125 levels. Histology of ovarian specimens revealed a diffuse large B cell lymphoma. A bone marrow biopsy revealed more than 80% infiltration with lymphoid cells. Two weeks after the laparotomy a computed tomography of her chest, abdomen, and pelvis revealed a pelvic mass, gross ascites, omental deposits, hepatosplenomegaly, and enlarged lymph nodes above and below her diaphragm. Immunohistochemistry confirmed the diagnosis of B cell lymphoblastic lymphoma. She was classified as stage IV E non-Hodgkin's lymphoma on the Ann Arbor staging system. CONCLUSION: This is an atypical presentation of an ovarian lymphoma. The atypical presentations of ovarian lymphomas can lead to diagnostic dilemmas.

Relationship between copper IUD complications and ultrasonographic findings.

OBJECTIVE: Intrauterine device (IUD) is a widely used long-acting contraceptive method; however, the side-effects related to IUD may lead to method discontinuation. The aim of this study is to evaluate the relation between the most common side-effects of IUD use; mainly dysmenorrhea, menorrhaghia, pelvic cramping and the relation of these complications with the position of the IUD device within the cavity and uterine dimensions evaluated by transvaginal ultrasonography. MATERIAL AND METHOD: Two hundred and eighty-four patients who had Cu-T380A IUD insertion at the Family Planning Clinic of a tertiary health center were evaluated at insertion and 6 and 12 weeks after the insertion. Demographic characteristics, medical history, symptoms and findings of the gynecological examination were recorded. Transvaginal ultrasonographic measurement of the uterine dimensions, the distance between the tip of the Cu-IUD and the fundus, myometrium and endometrium were measured to evaluate the displacement of the IUD. The relationship between the symptoms and IUD displacement diagnosed by ultrasonographic examination were investigated. RESULTS: Two hundred and sixty-seven patients were followed-up for 12 weeks as the remaining 16 had partial or complete IUD expulsion. A statistically significantly shorter uterine length was measured in patients who complained of menorrhagia in comparison to the ones without this complaint (54.27 ± 6.11 vs 60.25 ± 10.52 mm, p = 0.02) while uterine length was similar in patients with or without dysmenorrhea at 12 weeks (59.60 ± 10.25 vs 60.33 ± 10.68 mm, p = 0.71). The distances between the tip of the IUD and the endometrium, myometrium and the uterine fundus, were statistically and significantly longer in patients who experienced pelvic cramping at 3rd month, showing a downward movement of the IUD. (Endometrium; 0.29 ± 0.72 vs 0.45 ± 0.35 mm, p = 0.02, Myometrium; 1.25 ± 1.39 vs 2.38 ± 2.26 mm p < 0.05, Fundus; 1.68 ± 2.39 vs 2.92 ± 1.78 mm, p < 0.05). CONCLUSION: A shorter uterine cavity length seems to be a predictor of menorrhagia in patients with Cu-T 380A IUD. Patients experiencing pelvic cramping with IUD are more susceptible for IUD expulsion as the downward movement of IUD is more prominent in these patients.

Use of a levonorgestrel-releasing intrauterine device for menorrhagia treatment during adjuvant therapy of adrenocortical carcinoma with mitotane.

Adrenocortical carcinoma is a rare tumour with high malignancy and poor prognosis. This tumour is rarely diagnosed in the reproductive age. Complete surgical resection is the only curative treatment for adrenal cancer in all stages. After surgery adjuvant chemotherapy is required. Mitotane is the most important drug in adrenal cancer chemotherapy. Mitotane's mode of action is not entirely explained. Animal studies have shown that the substance exerts a direct cytotoxic effect on the cells of the adrenal cortex. This activity is selective, progressive and affects only the zona reticularis and fasciculata of the adrenal cortex. Mitotane inhibits cortisol synthesis by disrupting the chain of cholesterol. It has been suggested, that mitotane also affects the peripheral metabolism of steroids, especially of transcortin (CBG). This results in an increase of CBG blood concentration and a reduction of the amount of free hormones.

Cesarean section scar diverticulum evaluation by saline contrast-enhanced magnetic resonance imaging: The relationship between variable parameters and longer menstrual bleeding.

AIM: This study was conducted to determine a more accurate imaging method for the diagnosis of cesarean scar diverticulum (CSD) and to identify the parameters of CSD strongly associated with prolonged menstrual bleeding. METHODS: We enrolled 282 women with a history of cesarean section (CS) who presented with prolonged menstrual bleeding between January 2012 and May 2015. Transvaginal ultrasound, general magnetic resonance imaging (MRI) and contrast-enhanced MRI were used to diagnose CSD. Five parameters were compared among the imaging modalities: length, width, depth and thickness of the remaining muscular layer (TRM) of CSD and the depth/TRM ratio. Correlation between the five parameters and days of menstrual bleeding was performed. Finally, multivariate analysis was used to determine the parameters associated with menstrual bleeding longer than 14 days. RESULTS: Contrast-enhanced MRI yielded greater length or width or thinner TRM of CSD compared with MRI and transvaginal ultrasound. CSD size did not significantly differ between women who had undergone one and two CSs. Correlation analysis revealed that CSD (P = 0.038) and TRM (P = 0.003) lengths were significantly associated with days of menstrual bleeding. Longer than 14 days of bleeding was defined by cut-off values of 2.15 mm for TRM and 13.85 mm for length. TRM and number of CSs were strongly associated with menstrual bleeding longer than 14 days. CONCLUSIONS: CE-MRI is a relatively accurate and efficient imaging method for the diagnosis of CSD. A cut-off value of TRM of 2.15 mm is the most important parameter associated with menstrual bleeding longer than 14 days.

Outcomes in Adenomyosis Treated with Uterine Artery Embolization Are Associated with Lesion Vascularity: A Long-Term Follow-Up Study of 252 Cases.

PURPOSE: To study the therapeutic effects of uterine artery embolization (UAE) on adenomyosis and to investigate the association between uterine blood supply and artery embolization treatment outcomes. METHODS: Using digital subtraction angiography (DSA) imaging data, we retrospectively evaluated the vascular features of 252 adenomyosis patients treated with UAE. The cases were classified based on the equality of uterine blood supply (equal and unequal subgroups) and the degree of vascularity at the adenomyosis lesion site (hypervascular, isovascular and hypovascular subgroups). Patients were followed-up for 5 years after UAE. Improvements in dysmenorrhea and menorrhagia were evaluated based on the relief of the patients' symptoms. The improvement rates among the different subgroups were analyzed and compared. RESULTS: The improvement rates of dysmenorrhea and menorrhagia were 74.0% and 70.9%, respectively, at the short-term (12-month) follow-up and 70.4% and 68.8%, respectively, at the long-term (5-year) follow-up. No statistically significant differences were observed in the improvement rates for dysmenorrhea or menorrhagia between the equal and unequal blood supply subgroups at either the short- or long-term follow-up. The improvement rates for dysmenorrhea among the hypervascular, isovascular and hypovascular subgroups were 86.5%, 71.8% and 58.8%, respectively, at the short-term follow-up (p = 0.002) and 83.6%, 67.3% and 52.8%, respectively, at the long-term follow-up (p = 0.005). The improvement rates for menorrhagia in the hypervascular, isovascular and hypovascular subgroups were 81.0%, 68.3% and 60.7%, respectively, at the short-term follow-up (p = 0.024) and 79.4%, 61.4% and 62.2%, respectively, at the long-term follow-up (p = 0.052). CONCLUSION: UAE is effective in treating patients with adenomyosis in both the short and long term. The outcomes of patients with adenomyosis were significantly correlated with lesion vascularity.

Diagnosis of heavy menstrual bleeding.

Heavy menstrual bleeding (HMB) is an important health problem. This paper gives an overview of the diagnosis of HMB. For each woman, a thorough history should be taken as one should ascertain whether there are underlying factors that could cause complaints of HMB. Objectively knowing whether or not the blood loss is excessive could also be very beneficial. The pictorial blood assessment chart score can help with diagnosis. Physical examination starts with standard gynecological examination. Imaging tests are widely used in the work-up for women with HMB. The first step in imaging tests should be the transvaginal ultrasound. Other diagnostic tests should only be performed when indicated.

Can uterine artery Doppler parameters predict copper intrauterine device-induced side effects?

OBJECTIVES To evaluate the predictive value of uterine artery Doppler characteristics in predicting copper intrauterine device (IUD)-induced side effects such as dysmenorrhoea and menorrhagia, and worsening of dyspareunia. METHODS One hundred and twenty regularly menstruating women were enrolled in the study. All underwent transvaginal uterine artery Doppler analysis in the early follicular phase, on two occasions: before insertion of the IUD, and six months after insertion. Pre- and post-insertion resistance (RI) and pulsatility (PI) indices of the uterine arteries were measured. Doppler parameters were compared between subjects experiencing an increase in IUD-mediated side effects and those reporting no change. RESULTs RI and PI of all participants before and after IUD insertion were not significantly different (0.75 ± 0.06 vs. 0.74 ± 0.09, p = 0.49; 1.81 ± 0.55 vs. 1.83 ± 0.70, p = 0.7, respectively). No significant difference was found in the comparison of pre- and post-insertion PI and RI values of women who had increased- and those who experienced no change in dysmenorrhoea, dyspareunia and duration/amount of menstruation. CONCLUSIONS No major changes in uterine blood flow were observed in women experiencing increased menstrual bleeding, dyspareunia or dysmenorrhoea after insertion of a copper IUD. The occurrence of these effects cannot be predicted by prior Doppler flow analysis.

Is heavy menstrual bleeding investigated and managed appropriately?

Heavy menstrual bleeding (HMB) accounts for approximately 20% of gynaecology referrals. The National Institute of Clinical Excellence (NICE) recommendations provide the framework for evidence-based management of HMB. Despite this, previous studies have highlighted significant variation in the investigation and management of HMB. This was an observational study of clinical practice performed by retrospective case note reviews of 43 women referred to the Royal Bolton NHS Foundation Trust with HMB between May and June 2011. The care that these women received was evaluated and compared with that currently recommended by clinical guidelines. The investigation and management of HMB in both primary and secondary care was variable, often failing to meet standards recommended by NICE. Greater awareness of NICE guidance may result in improved care. Educational sessions and information provision targeted at healthcare professionals who manage women with HMB, may be beneficial.

Three-dimensional power Doppler study of endometrial and subendometrial microvascularization in women with intrauterine device-induced menorrhagia.

OBJECTIVE: To evaluate endometrial and subendometrial microvascularization, using three-dimensional (3D) power Doppler ultrasound, in women with intrauterine device (IUD)-induced menorrhagia; and whether those potential findings could predict the risk of bleeding before IUD insertion. DESIGN: Prospective clinical trial. SETTING: University teaching hospital. PATIENT(S): One hundred twenty women, who requested the insertion of a copper IUD for contraception. INTERVENTION(S): Endometrial thickness and volume, uterine artery pulsatility index and resistance index, and endometrial and subendometrial 3D power Doppler vascularization index, flow index, and vascularization flow index were measured twice: immediately before and 3 months after IUD insertion. MAIN OUTCOME MEASURE(S): Doppler indices before and after IUD insertion. RESULT(S): Before IUD insertion, no significant difference was detected in the clinical characteristics, endometrial thickness and volume, and Doppler indices between women who had IUD-induced menorrhagia (n = 47) and those without menorrhagia (n = 73). However, after IUD insertion, there was a significant increase in the endometrial and subendometrial vascularization index, flow index, and vascularization flow index in women with menorrhagia, whereas other parameters remained not significantly different between the two groups. CONCLUSION(S): Endometrial and subendometrial microvascularization increases in women with IUD-induced menorrhagia; however, this finding has no predictive value before IUD insertion.

Fibroid-associated heavy menstrual bleeding: correlation between clinical features, Doppler ultrasound assessment of vasculature, and tissue gene expression profiles.

Despite the prevalence of uterine fibroids (Fs), few studies have investigated the links between clinical features and the cellular or molecular mechanisms that drive F growth and development. Such knowledge will ultimately help to differentiate symptomatic from asymptomatic Fs and could result in the development of more effective and individualized treatments. The aim of this study was to investigate the relationship between ultrasound appearance, blood flow, and angiogenic gene expression in F, perifibroid (PM), and distant myometrial (DM) tissues. We hypothesized that angiogenic gene expression would be increased in tissues and participants that showed increased blood flow by Doppler ultrasound. The study was performed using Doppler ultrasound to measure blood flow prior to hysterectomy, with subsequent tissue samples from the F, PM, and DM being investigated for angiogenic gene expression. Overall, PM blood flow (measured as peak systolic velocity [PSV]) was higher than F blood flow, although significant heterogeneity was seen in vascularity and blood flow between different Fs and their surrounding myometrium. We did not find any correlation between PSV and any other clinical or molecular parameter in this study. We identified 19 angiogenesis pathway-related genes with significant differences in expression between F and DM, and 2 genes, matrix metalloproteinase 9 (MMP9) and Neuropilin 2 (NRP2), that were significantly different between F and PM. These results are consistent with subtle differences between PM and DM. Understanding the differences between symptomatic versus asymptomatic Fs may eventually lead to more effective treatments that directly target the source of heavy menstrual bleeding.

Sonographic findings in two cases of complicated pregnancy in women previously treated with endometrial ablation.

When medical therapy fails for menorrhagia in a premenopausal woman, minimally invasive endometrial ablation can be used as a conservative management alternative to hysterectomy. Endometrial ablation alone is not considered effective contraception, and women of reproductive age can become pregnant after ablative therapy. We now present two cases of pregnancy after endometrial ablation and associated imaging where both cases required cesarean hysterectomy due to post-partum hemorrhage. Pregnancy after endometrial ablation incurs increased morbidity and diagnostic dilemmas.

Is it possible to obtain a presurgical Lasmar score for hysteroscopic myomectomy by ultrasound alone?

OBJECTIVE: To determine whether a Lasmar score obtained entirely by the use of two-dimensional (2D) and three-dimensional (3D) ultrasound provides results similar to those obtained using the original hysteroscopic technique. METHODS: This was a prospective study performed on a series of patients presenting with symptomatic submucous fibroids and scheduled for hysteroscopic myomectomy. Ultrasound Lasmar scores were obtained by a single physician, a specialist in ultrasonography, in the luteal phase of the menstrual cycle. 3D images were evaluated by offline examination using multiplanar analysis. Classical Lasmar scores were obtained by a different physician, a specialist in hysteroscopy, during the follicular phase of the subsequent cycle. Surgery was performed by a third physician in the follicular phase who also reported a Lasmar score, which we considered as the gold standard. The concordance between group classifications (I-III, relating to difficulty of hysteroscopic resection) according to the three methods used to obtain the Lasmar score (ultrasound, classical and surgery) was calculated using Cohen's κ statistic. RESULTS: Thirty-four women, with a mean age of 43 ± 4.9 years, were enrolled in the study. Thirty-six submucous fibroids were identified by both ultrasound and diagnostic hysteroscopy. The mean diameter of fibroids evaluated was 28 ± 13.2 mm. The concordance between the three methods of classifying patients according to Lasmar score was high: classical vs. surgery, κ = 0.88; ultrasound vs. surgery, κ = 0.93; and classical vs. ultrasound, κ = 0.77. CONCLUSION: The Lasmar score can be obtained solely by ultrasound examination performed in the luteal phase of the menstrual cycle, avoiding office hysteroscopy without a loss of diagnostic accuracy.

Levonorgestrel releasing-intrauterine system for the treatment of menorrhagia and/or frequent irregular uterine bleeding associated with uterine leiomyoma.

OBJECTIVE: To evaluate the effectiveness of the levonorgestrel releasing-intrauterine system (LNG-IUS) in the treatment of menorrhagia and/or frequent irregular uterine bleeding in women with uterine myomas. STUDY DESIGN: Prospective study whereby 102 women with intramural myomas (in a few cases associated with submucous or subserous myomas), suffering from menorrhagia and/or frequent irregular uterine bleeding, were evaluated by means of the Pictorial Blood Assessment Chart (PBAC; Higham score) and ultrasound, three, six and 12 months after insertion of a LNG-IUS. RESULTS: The PBAC score dropped (from a mean value of 231.7 to 17.6 at 12 months). The duration of menstrual bleeding diminished significantly (p<0.001). Uterine volume decreased from a mean of 145 cm3 to 129 cm3 at 12 months (p=0.01). Changes in the volume of the myomas were not statistically significant (p=0.23). Satisfaction rate was good in 91 cases (89%), fair in four cases (4%), and poor in seven cases (7%). During the one-year period of follow-up, 11 cases of expulsion or removal of the LNG-IUS were recorded. CONCLUSION: The LNG-IUS is effective in controlling heavy menorrhagia and/or frequent irregular uterine bleeding related to the presence of myomas, but has no significant effect on the size of the tumours.

Comparison of diagnostic accuracy of saline infusion sonohysterography, transvaginal sonography and hysteroscopy.

We aimed to compare the accuracy of transvaginal sonography (TVS), saline infusion sonohysterography (SIS) and hysteroscopy (HS) for uterine pathologies among infertile women. A total of 346 patients were selected for operative hysteroscopy, following SIS after TVS. SIS was performed with a Cook Soft 500 IVF catheter. Sensitivity, specificity, positive and negative predictive values (PPV, NPV) were calculated to compare the accuracy of TVS, SIS and hysteroscopy for uterine abnormalities. SIS showed a sensitivity of 87%, specificity of 100% and PPV of 100% for endometrial hyperplasia, and a sensitivity and NPV of 100% for polypoid lesions. For submucosal myoma SIS showed a sensitivity of 99% with PPV of 96%. Hysteroscopy had a sensitivity, specificity, PPV and NPV of 98%, 83%, 96% and 91%, respectively for overall uterine pathologies. Finally, SIS seems to be superior to TVS, for uterine pathologies, with respect to hysteroscopy as the gold standard.
