Postmenopausal Bleeding

To evaluate hysteroscopic findings in women with postmenopausal bleeding and correlate them with histopathological results of the endometrium., Sohag University Hospital Obstetrics and Gynecology department

The goal of this randomized controlled trial is to evaluate the effectiveness of different cervical preparation strategies before office hysteroscopy in postmenopausal women undergoing evaluation for intrauterine pathology. The main questions to answer are: Does cervical preparation improve the success rate of complete office hysteroscopy in postmenopausal women? Which cervical preparation strategy provides better patient tolerance, as assessed by pain intensity during the procedure? Researchers will compare four cervical preparation protocols (14-day vaginal estrogen, 7-day vaginal estrogen, oral misoprostol, and no cervical preparation) to determine their effects on procedural success, pain, procedure duration, and perioperative complications. Participants will be randomly assigned to one of the four cervical preparation protocols. They will undergo office hysteroscopy using a vaginoscopic ("no touch") approach without anesthesia. Then, they will have pain assessed using a visual analog scale (VAS) during the procedure. Finally, these informations will be collected: procedural success, procedure duration, bleeding, and perioperative complications.

The goal of this observational study is to investigate the clinical utility of DNA-methylation testing in urine and vaginal samples collected by patients and cervical samples collected by clinicians, to determine the risk of endometrial cancer in symptomatic women with postmenopausal bleeding. The study aims to answer the following research questions: * What is the diagnostic accuracy of DNA methylation testing in urine, vaginal and cervical samples compared to traditional TVUS for endometrial cancer detection? * What is the 2-year risk of EC among women testing negative on TVUS and/or DNA methylation tests or those testing positive on methylation only? Researchers will compare DNA methylation testing in patient-collected urine and vaginal samples as well as in clinician-collected cervical samples, with the traditional diagnostic pathway for women with PMB, which includes TVUS evaluation, and when indicated by abnormal TVUS findings, endometrial biopsy according to clinical guidelines. Participants will * take a urine and vaginal sample * have a cervical sample collected by a clinician * undergo TVUS evaluation according to clinical guidelines * If TVUS shows thickened endometrium (≥ 5 mm) and/or irregularity, an endometrial biopsy will be collected according to clinical guidelines * fill out a questionnaire regarding acceptability and preferences of sampling methods and complete a lifestyle questionnaire.
