Objectives: The current study aimed to accurate preoperative local staging of patient with endometrial cancer. Patients and Methods: This prospective cross-sectional study was performed at Zagazig University Hospital department of obstetrics and gynecology from May to December 2021. During the study period (6 months), 8 cases/ month, 48 cases were included as a comprehensive sample. The cases with following criteria were included in the present study, cases diagnosed as having endometrial carcinoma by endometrial sampling (blind D&C, pipelle, or hysteroscopy). Results: The current results found that the sensitivity was 81%, specificity was 50% and the accuracy of ultrasound detection degree of myometrial invasion was 67%. The ultrasonography had 0% sensitivity in diagnosis of LN involvement and 100% specificity, 87.5% NPV and accuracy 87.5%. Our findings revealed that ultrasonography in diagnosis patients with cervical involved was moderate in accuracy about 73% Conclusion: Ultrasound imaging was significantly accurate for endometrial carcinoma staging preoperatively. There was a good correlation of TVUS with pathological results. TVUS evaluation proved to be a potential preoperatively guiding tool for non-bulky tumors and also a remarkable sensitive tool for excluding or detecting invasion.
