Measurement Of Endometrial Thickness Research Articles

The entire range of trigger-day endometrial thickness in fresh IVF cycles is independently correlated with live birth rate.

What is the association of the entire range of trigger-day endometrial thickness (EMT) with live birth rate (LBR) after IVF and fresh embryo transfer? Although EMT is amenable to convenient non-invasive routine measurement, studies of the association between pre-trigger EMT and assisted reproductive technology outcome have yielded equivocal results. A cohort of IVF fresh day-3 embryo transfers in patients aged 42 years and younger in a single centre between 2009 and 2017. The LBR was calculated for all trigger-day EMT values, stratified into five groups overall and within subgroups of patient age and ovarian response. Univariate analysis and multivariate logistic regression models were used to compare the LBRs at different EMT measurements adjusting for various independent variables. A total of 5133 cycles were included. The LBRs were as follows: 11.22% (35/312) in cycles with EMT 6 mm or less, 17.98% (380/2114) in cycles with EMT 7-9 mm, 23.44% (476/2031) in cycles with EMT 10-12 mm, 25.62% (144/562) in cycles with EMT 13-15 mm and 34.21% (39/114) in cycles with EMT 16 mm or more (P < 0.001). Similar findings were observed by patient age and ovarian response. The observation was confirmed by multivariate logistic regression analysis in which the EMT was found to be a significant independent predictor of LBR even after controlling for various confounders (OR 0.935, 95% CI 0.908 to 0.962; P < 0.001). Pre-trigger EMT is in significant independent correlation with LBR, even after adjusting for age and ovarian response. Maximal endometrial proliferation is beneficial, and fresh embryo transfer can be carried out at high EMT values without endangering the outcome of the cycle.

Endometrial compaction before frozen euploid embryo transfer improves ongoing pregnancy rates

To assess whether the calculated difference in endometrial thickness from the end of the estrogen phase to the day of ET (after 6 days of P in hormonally prepared cycles) is associated with ongoing pregnancy rates in euploid frozen ETs (FETs). An observational cohort study. Single tertiary care medical center. Ultrasound images from 234 hormonally prepared FET cycles were assessed. All the transfers were elective single ETs of a euploid embryo, post-preimplantation genetic testing for aneuploidy (PGT-A). Ultrasound measurements of peak endometrial thickness at the end of the estrogen phase and again after 6 days of P at the time of ET. Ongoing pregnancy rate in relation to the delta between endometrial thickness at the end of estrogen phase and at the time of ET. We calculated the ongoing pregnancy rate in cycles where the endometrial lining decreased (compacted) after addition of P by 5%, 10%, 15%, and 20% and demonstrated a significantly higher pregnancy rate after all rates of compaction of the endometrial lining in comparison with cycles where the endometrial lining did not compact. The ongoing pregnancy rate in this cohort, after compaction of 15% or more, was 51.5%, compared with 30.2% in cycles where the endometrial lining did not compact. There is a significant correlation between endometrial lining compaction and ongoing pregnancy rate in FET cycles of euploid embryos. These findings help to explain why some euploid embryos may fail to implant.

Correlation Between Endometrial Thickness By Ultrasonography and Histopathology in Abnormal Uterine Bleeding

Background : Abnormal uterine bleeding (AUB) is the most common presenting complaint of patients in Gynaecology Outpatient department. Early diagnosis of endometrial hyperplasia through ultrasongraphic measurement of endometrial thickness and definite diagnosis by histopathologic examination will help the clinicians to give appropriate treatment to the patients. The objective of this study was to correlate the histopathology findings in abnormal uterine bleeding with endometrial thickness by ultrasonography. Methods : This was a prospective study done from Nov 2016 to June 2018.A total of 382 cases of AUB presenting above 40 years of age were included. Endometrial thickness was measured by ultrasonography. Histopathological findings were studied and compared with the endometrial thickness. Statistical analysis were done using chi square test. Results : A total of 382 cases were analysed. Maximum number of cases were from peri menopausal age group (68.32%). Majority of the cases were due to non organic causes(85.34%). 46.86% of patients had endometrial thickness of 5-10mm followed by endometrial thickness of 11-15mm in 39.01%. Disordered proliferative endometrium was the most common pattern (38.34%) in our study followed by secretory endometrium (35.58%) and menstrual endometrium (18.71%). These findings were found to be statistically significant. Conclusion : A thorough histopathological work up and clinical correlation is mandatory in cases of abnormal uterine bleeding above 40 years to find out organic lesions. Careful screening can detect precursor lesions like endometrial hyperplasia and early cases of endometrial carcinoma which has excellent prognosis and it will help in further management.

Role of Transvaginal Ultrasound in Detection of Endometrial Changes in Breast Cancer Patients under Hormonal Therapy

Abstract Background Hormonal therapy is widely utilized as adjuvant therapy in women diagnosed with breast cancer, in those patients, Despite its positive risk/benefit ratio, It may cause secondary effects on the endometrium, Including endometrial atrophy, Endometrial polyp, Endometrial hyperplasia, and up to Endometrial carcinoma. Aim of the Work We aim to determine the role of TVUS in detection of endometrial changes. Aim and Patients and Methods Cross sectional Prospective study.

Local ultra-low-dose estriol gel treatment of vulvo-vaginal atrophy: efficacy and safety of long-term treatment

Vulvo-vaginal atrophy (VVA) is a chronic condition affecting many postmenopausal women. Local estrogen treatment is recommended. Evaluating efficacy and safety of long-term VVA treatment with ultra-low-dose estriol gel, 120 postmenopausal VVA women were enrolled in a prospective study. They received the first cycle of 1 g/day vaginal gel containing 50 µg estriol for 3 weeks and then twice a week for 12 weeks. Moderate or severe VVA women received a second treatment cycle reaching treatment of 30 weeks. Vaginal pH measurement, subjective symptoms, and objective signs assessment of VVA, endometrial thickness and adverse events (AE) were recorded. Of the 99 women, completing the first phase, 43% experienced a complete VVA symptom relief, and 65% presented a milder VVA degree. After 30 weeks, VVA signs significantly improved (p<.01) compared with baseline and first phase results; total objective symptom evaluation including Schiller’s test, flattening of folds and vaginal pH significantly improved (p<.01). At study endpoint, none of the patients had severe VVA, 93% had a positive response, 75% had a complete symptom, and sign resolution. No treatment-related endometrial AE were observed. Postmenopausal VVA long term-treatment with ultra-low-dose estriol vaginal gel is safe and effective.

Letrozole or Clomiphene Citrate for Induction of Ovulation in Patients with Polycystic Ovarian Syndrome: A Prospective Randomized Trial

Polycystic Ovarian Syndrome (PCOS) is the most common endocrine disorder responsible for subfertility in young women. The aim of the study was to compare the efficacy of Letrozole over Clomiphene citrate (CC) for ovulation induction in patients with PCOS. It was a prospective randomized trial in a private practice setting. The study period was 3 years, which includes 240 sub fertile patients with PCOS. Patients were divided into two groups. Group-A: 120 patients got Letrozole (2.5 mg) tab, 2 tabs once daily from D2-D6 for 3 cycles. Group-B: 120 patients took tab. Clomiphene citrate (50mg), 2 tabs once daily from D2-D6 for 3 cycles. Trans-vaginal ultrasound was done on D12-D13 to document number of follicles, measurement of dominant follicle and endometrial thickness. Ovulation and pregnancy rate was measured. Results showed that Letrozole have significantly better effect on endometrial thickness (Let 9.2 mm vs CC 8.1mm) and pregnancy rate (Let 44% vs CC 24%). In CC, multiple follicles were found (CC 44% vs Let 30%). Ovulation occurred in 65% with Letrozole group and 64% in CC group without a significant statistical difference. The study concluded that Letrozole have better effect for induction of ovulation in PCOS patient in comparison to CC. Faridpur Med. Coll. J. Jul 2018;13(2): 78-81

Embryo transfer strategy and therapeutic options in infertile patients with thin endometrium: a systematic review.

Human endometrium has a key role in implantation process. The measurement of endometrial thickness is the most commonly used in clinical practice. Managing patients with thin endometrium still represents a major challenge for clinicians. The objective of this systematic review was to investigate all available interventions to improve endometrial thickness (EMT) in women with history of thin endometrium undergoing fresh or frozen-thawed embryo transfers (ET). We performed a comprehensive search of relevant studies from January 1978 to February 2018. The different strategies were categorized as hormonal, vascular, and growth factor approaches and specifically analyzed according to the type of ET. Thirty-one studies were included. Overall, quality of the evidence ranged from very low to moderate, with only few randomized controlled trials that support the use of either GnRH analogues in fresh ET or sildenafil in frozen ET for enhancing endometrial growth. Besides, intensified estradiol administration is a common approach that might improve EMT in frozen ET. The present review evidences the paucity of reliable data regarding the efficiency of different interventions aiming at increasing EMT before fresh or frozen-thawed ET. Robust and high-quality randomized controlled trials are still needed before guidelines can be established.

A Clinico-pathological Study of Transvaginal Endometrial Thickness Measurement in Asymptomatic Postmenopausal Patients and Patients with Postmenopausal Bleeding

Objective: We aimed to determine the frequency of endometrial pathologies of patients who presented to our outpatient clinic with postmenopausal bleeding (PMB) and asymptomatic menopausal patients with a finding of thickened endometrium on transvaginal ultrasonography.Study Design: This study was performed at Bezmialem University Hospital. Women who presented to our clinic from January 2015 to January 2017 were analyzed. Patients were divided to two groups. All patients underwent transvaginal ultrasound with a 7.5 MHz probe. Endometrial sampling was performed by either blind D&amp;C (dilatation &amp; curettage) or pipelle sampling. We excluded patient specimens that were obtained by hysteroscopy.Results: Electronic records of a total of 368 patients in menopause were inspected. Out of these patients; 287 (78%) underwent endometrium sampling indicated by bleeding. Eighty-one patients (22%) were asymptomatic; however, a thickened endometrium echo on TVUSG examination (≥ 5 mm) was suspected. The median age was 57 (42-85). In both groups the two leading causes of endometrial pathology was; endometrial polyps followed by proliferative endometrium. The frequency of endometrial cancer was 9.4 % for the PMB group and 1.2 % in the asymptomatic patient groupConclusion: Evaluation of PMB as soon as possible is essential for diagnosing endometrial pathologies. Role of endometrial thickness is decisive in detecting patients at high risk for malignancy especially with comorbid conditions. Histopathological evaluation is mandatory for ruling out malignancy.

Deep Learning-Based Automatic Endometrium Segmentation and Thickness Measurement for 2D Transvaginal Ultrasound.

Endometrial thickness is closely related to gyneco-logical function and is an important biomarker in transvaginal ultrasound (TVUS) examinations for assessing female reproductive health. Manual measurement is time-consuming and subject to high inter- and intra- observer variability. In this paper, we present a fully automated endometrial thickness measurement method using deep learning. Our pipeline consists of: 1) endometrium segmentation using a VGG-based U-Net, and 2) endometrial thickness estimation using medial axis transformation. We conducted experimental studies on 137 2D TVUS cases (74/63 secretory phase/proliferative phase). On a test set of 27 cases/277 images, the segmentation Dice score is 0.83. For thickness measurement, we achieved mean absolute error of 1.23/1.38 mm and root mean squared error of 1.79/1.85 mm on two different test sets. The results are considered well within the clinically acceptable range of ±2 mm. Furthermore, our phase-stratified analysis shows that the measurement variance from the secretory phase is higher than that from the proliferative phase, largely due to the high variability of the endometrium appearance in the secretory phase. Future work will extend our current algorithm toward different clinical outcomes for a broader spectrum of clinical applications.

Endometrial compaction (decreased thickness) in response to progesterone results in optimal pregnancy outcome in frozen-thawed embryo transfers

To evaluate whether the change in endometrial thickness between the end of the estrogen phase and the day of embryo transfer has an impact on the pregnancy rate in frozen-thawed embryo transfer (FET) cycles. Retrospective observational cohort study. Single tertiary care medical center. Ultrasound images in 274 FET cycles were reviewed. All patients underwent endometrial preparation with the use of hormonal therapy. Ultrasound measurements of endometrial thickness at the end of the estrogen phase and the day of embryo transfer. The change in endometrial thickness and ongoing pregnancy rate. We calculated the ongoing pregnancy rate in patients whose endometrial thickness decreased (compacted) after starting progesterone by 5%, 10%, 15%, or 20% compared with patients with no change or increased endometrial thickness. The ongoing pregnancy rate was significantly increased at all levels of compaction compared with no compaction. The ongoing pregnancy rate showed a significant increase with each decreasing quartile of change in thickness (increased percentage of compaction) in the progesterone phase compared with the estrogen phase. There is a highly significant inverse correlation between the ongoing pregnancy rate and the change of endometrial thickness between the end of estrogen administration and the day of embryo transfer.

Endometrial thickness cut-off value by transvaginal ultrasonography for screening of endometrial pathology in premenopausal and postmenopausal women.

ObjectiveTo assess the clinical usefulness and diagnostic accuracy of ultrasonographic measurement of endometrial thickness (ET) in women with endometrial hyperplasia or cancer (EH+).MethodsThis retrospective cohort study included 29,995 consecutive women who underwent transvaginal ultrasonography (TVS) for an incidental finding of a thickened endometrium at the health screening and promotion center at Asan Medical Center between 2006 and 2010. Among 959 patients with endometrial abnormalities, 92 patients were included in this study. A total of 867 patients were excluded: 416 were lost to follow-up; 263 did not undergo endometrial biopsy; 155 had endometrial polyps; 17 had submucosal myomas; and 16 had insufficient tissue samples. Endometrial histology was the reference standard for calculating accuracy.ResultsOf the 92 patients, 78 (84.8%) had normal pathology, while 14 (15.2%) had endometrial pathology (EH+), including 5 patients (35.7%) with simple hyperplasia without atypia, 3 (21.4%) with complex hyperplasia, and 6 (42.9%) with endometrial carcinoma, all stage Ia. The area under the receiver-operating characteristic curve was 0.75 (95% confidence interval [CI], 0.593–0.906). The cut-off value for ET was 8 mm, indicating that TVS ET had a fair accuracy in diagnosing carcinoma, had a sensitivity of 100% (95% CI, 62.9–100.0%) and a specificity of 24.3% (95% CI, 15.2–36.3%).ConclusionTVS is useful for detecting EH+, with a cut-off value for ET of 8 mm having a high sensitivity for detecting endometrial pathologies and the ability to identify women highly unlikely to have EH+, thereby avoiding more invasive endometrial biopsy.

Asymptomatic Endometrial Thickening of 8 mm or Greater on Postcontrast Computed Tomography in Postmenopausal Women Is a Predictor of Endometrial Cancer.

The aim of this study was to assess the value of opportunistic endometrial thickness measurement on postcontrast computed tomography (CT) as a predictor of endometrial cancer in asymptomatic postmenopausal women. For this Health Insurance Portability and Accountability Act-compliant, institutional review board-approved retrospective study with waiver of informed consent, our institution's tumor board database was searched for postmenopausal patients, diagnosed with endometrial cancer between August 2003 and December 2016 and who had a postcontrast pelvic CT within 12 months prior to the cancer diagnosis (while they were asymptomatic)-"cancer group." Same number of age-matched patients who had postcontrast pelvic CT constituted the noncancer control group. Endometrial thickness was measured on sagittal postcontrast CT images. After applying exclusion criteria, 22 asymptomatic patients who were diagnosed with endometrial cancer within 1 year after the CT comprised the cancer group, and 22 age-matched patients comprised the control group. Average endometrial thickness was 18.7 ± 14.8 mm (range, 2-70 mm) in the cancer group and 3.6 ± 2.5 mm (range, 1.8-10 mm) in the control group (P < 0.0001). Endometrial thickness 8 mm or greater predicted endometrial cancer with 86% sensitivity and 91% specificity in these asymptomatic patients. Area under the receiver operating characteristic curve for endometrial thickness as a predictor of endometrial cancer was 0.92. Endometrial thickness 8 mm or greater on sagittal postcontrast CT was shown to have high sensitivity in opportunistic detection of endometrial cancer in asymptomatic postmenopausal women.

Uses of Ultrasound and Doppler in Assessment of Endometrial Receptivity in Patients of Unexplained Infertility

Background:although the majority of infertile couples was found to have an identifiable male or female factor, 15–30% was categorized as having ‘‘unexplained infertility’’. The endometrium is considered to be a key determinant in successful implantation. Endometrial receptivity is regulated by many factors including endometrial perfusion. Aim of the Work: this study aimedto detect the role of the two dimensional ultrasound and Doppler ultrasonographic uterine markers of implantation in patients of unexplained infertility compared to fertile participants. Patients and Methods: the study was performed on 50 patients presented to the outpatient clinic in Al-Hussein, Bab El-Shearia (Sayed Galal) Hospitals, Al-Azhar University from October 2017 to August 2018 and they were categorized into two groups: Group A (Patients group): it was included 30 participants presented with unexplained infertility. Group B) (Control group) who included 20 fertile women coming for contraception. Results: there was a significant statistical difference as regard the endometrial thickness between cases and controls, and the controls had a thicker endometrium. Lower pulsatility index (PI) in uterine artery in the controls compared to the infertile group. Increased sub endometrial vascularization in the controls compared to the infertile group. Conclusion:ultrasound as well as Doppler studies of the endometrial and subendometrial vascularization had a role in predicting endometrial receptivity. Uterine artery Doppler study and the endometrial thickness measurement had a role in detection of uterine receptivity.

The impact of a thin endometrial lining on fresh and frozen–thaw IVF outcomes: an analysis of over 40 000 embryo transfers

STUDY QUESTIONDoes each millimeter decrease in endometrial thickness lead to lower pregnancy and live birth rates in fresh and frozen IVF cycles?SUMMARY ANSWERClinical pregnancy and live birth rates decline as the endometrial thickness decreases below 8 mm in fresh IVF-ET and below 7 mm in frozen–thaw embryo transfer (ET) cycles.WHAT IS KNOWN ALREADYPrevious studies have been heterogenous and have shown conflicting results on the impact of endometrial thickness on IVF outcomes. Most studies do not include many patients with an endometrial thickness below 6 mm, and there are few studies of frozen–thaw ET cycles.STUDY DESIGN, SIZE, DURATIONThis study is a retrospective cohort analysis of all Canadian IVF fresh and frozen–thaw ET cycles from the CARTR-BORN database for autologous and donor fresh and frozen–thaw IVF-ET cycles from 1 January 2013 to 31 December 2015. A total of 24 363 fresh and 20 114 frozen–thaw IVF-ET cycles were reported during this timeframe.PARTICIPANTS/MATERIALS, SETTING, METHODS33 Canadians clinics participated in voluntary reporting of IVF and pregnancy outcomes to the CARTR-BORN database. The impact of endometrial thickness on pregnancy, live birth and pregnancy loss rates were analyzed for fresh IVF-ET and frozen–thaw cycles.MAIN RESULTS AND THE ROLE OF CHANCEIn fresh IVF-ET cycles, clinical pregnancy and live birth rates decreased (P < 0.0001) and pregnancy loss rates increased (P = 0.01) with each millimeter decline in endometrial thickness below 8 mm. Live birth rates were 33.7, 25.5, 24.6 and 18.1% for endometrial thickness ≥8, 7–7.9, 6–6.9 and 5–5.9 mm, respectively. In frozen–thaw ET cycles, clinical pregnancy (P = 0.007) and live birth rates decreased (P = 0.002) with each millimeter decline in endometrial thickness below 7 mm, with no significant difference in pregnancy loss rates. Live birth rates were 28.4, 27.4, 23.7, 15 and 21.2% for endometrial thickness ≥8, 7–7.9, 6–6.9, 5–5.9 and 4–4.9 mm, respectively. The likelihood of achieving an endometrial thickness ≥8 mm decreased with age (89.7, 87.8 and 83.9% in women <35, 35–39 and ≥40, respectively) (P < 0.0001).LIMITATIONS, REASONS FOR CAUTIONThis study only included cycles which proceeded to ET, which may overestimate pregnancy outcomes. Approximately 8% of cycles could not be included in the analysis due to data irregularity related to data entry. Demographic data aside from age were unavailable but may be important as lower endometrial thickness may be associated with poor ovarian response.WIDER IMPLICATIONS OF THE FINDINGSAlthough pregnancy and live birth rates decrease with endometrial thickness, reasonable outcomes were obtained even with lower endometrial thickness measurements. These data provide valuable guidance for both physicians and patients when confronted with decisions related to a persistently thin endometrium.STUDY FUNDING/COMPETING INTEREST(S)This study was not funded.

Evidence of negative relationship between female fertility and feed efficiency in Nellore cattle.

The objective of this study was to evaluate phenotypic and genetic relationships between fertility traits and feed efficiency in male and female Nellore cattle. Data from 320 females born between 2004 and 2011 were used for phenotypic evaluation. These animals were evaluated for postweaning residual feed intake (RFI) and classified as negative (RFI < 0, mean = -0.294 ± 0.017 kg DM/d) or positive RFI (RFI > 0, mean = 0.305 ± 0.0189 kg DM/d). Of these, 118 prepuberal heifers were submitted to ultrasonography of the uterus and ovaries for monitoring the presence (or absence) of a corpus luteum and for the measurement of endometrial thickness. The following fertility traits were evaluated in all females: age at first calving, days to calving, first calving interval, calving success, stayability, and longevity. The variance components were estimated by the average information restricted maximum likelihood method under an animal model in 5-trait analysis of backfat and rump fat thickness, scrotal circumference, days to calving, and RFI. The total number of animals with records was 6,718, including 927 males with records of scrotal circumference and RFI and 264 females with records of days to calving and RFI. Negative RFI females consumed 12.5% less DM daily than positive RFI females and had a lower rump fat thickness when evaluated postweaning. Among the fertility traits studied, only first calving interval differed (P = 0.0858) between RFI classes, with the interval of negative RFI females being 45 d shorter than that of positive RFI animals. The heritability estimates were 0.29, 0.34, 0.50, 0.12, and 0.16 for backfat and rump fat thickness, scrotal circumference, days to calving, and RFI, respectively. The genetic correlations between RFI and the other traits studied were unfavorable for selection and were of moderate magnitude with backfat thickness, rump fat thickness, and days to calving (0.53, 0.37, and -0.49, respectively) and close to zero with scrotal circumference (0.07). Scrotal circumference (0.17 and 0.15) and days to calving (-0.10 and -0.22) were weakly and favorably correlated with backfat and rump fat thickness. There is evidence of moderate genetic antagonism between female fertility and feed efficiency, but with no evidence of a genetic correlation between male fertility and feed efficiency. There is also evidence of low genetic synergism between fat thickness and fertility.

Evaluating the Endometrial Hyperechoic Zone in Early Postpartum Women May Be Deceptive When Utilizing Transcutaneous Sonography

The objective of this study was to investigate the concordance of measurements for early postpartum endometrial thickness between magnetic resonance imaging (MRI) and transcutaneous diagnostic medical sonography (DMS) as well as its implications. The measurements of early postpartum endometrial thickness were reviewed across 51 postpartum women who underwent MRI and transcutaneous DMS. Additionally, 30 women with a normal menstrual cycle formed a control group, and their data were compared. The results indicated that the endometrial thickness at early postpartum was 4.63 ± 0.62 mm on MRI and 8.18 ± 4.70 mm on DMS, with a comparative significant difference ( P &lt; .001). The endometrial thickness of the control group was 10.02 ± 1.71 mm on MRI and 10.17 ± 1.81 mm on DMS with no comparative significant difference ( P = .124). This cohort study questions whether the hyperechoic zone in the early postpartum uterine cavity represents the actual endometrial thickness. Care should be taken by sonographers in labeling the hyperechoic zone in the early postpartum stage as endometrium.

Endometrial study by Ultrasonography and its correlation with Histopathology in Abnormal uterine bleeding

Background: Abnormal Uterine Bleeding is defined as any deviation from a normal menstrual pattern. It is one of the common presentation in extremes of ages. However endometrial hyperplasia and carcinoma are commoner in perimenopausal and postmenopausal women warranting investigations like ultrasonography and endometrial biopsy.Aims and Objective: The aim of the study was to note the endometrial thickness by transabdominal ultrasonography and observe the histopathological pattern in women presenting with abnormal Uterine Bleeding.Material and Methods: Premenopausal women more than 45 years of age and the postmenopausal patients, without any pelvic pathology were included in the study. Endometrial thickness was measured by transabdominal sonography and endometrial biopsy was done. Tissue obtained was sent for histopathological examination.Results: A total of 105 patients were studied. Majority (92%) of patients were premenopausal. Proliferative Endometrium (32%) was the most common finding in premenopausal and atrophic endometrium (37.5%) in postmenopausal group. Malignancy was higher in a postmenopausal group (12.5%) as compared to the premenopausal group (2%). Malignancy was not seen when endometrial thickness was less than 11mm in the premenopausal age group. Endometrial hyperplasia was also more common when the thickness was more than 11mm.In postmenopausal group12.5% of patients, had complex hyperplasia.25% had simple hyperplasia and malignancy was seen in 12.5% of patients. When endometrial thickness was less than 5 mm, hyperplasia and malignancy was not seen.Conclusion: Measurement of Endometrial thickness and histopathological workup in patients above 45 years presenting with abnormal uterine bleeding will be helpful in detecting endometrial hyperplasia and carcinoma.Asian Journal of Medical Sciences Vol.9(2) 2018 31-35
