Background: The local application of stains or dyes during endoscopy is referred to as "chromoendoscopy" in an attempt to improve tissue identification, distinction, and diagnosis. Objectives: To judge the value of chromohysteroscopy in identifying endometrial abnormalities that are too subtle for standard hysteroscopy to detect. The histopathology from routine endometrial sampling and chromohysteroscopy was compared. Methodology: This interventional prospective study included 49 women with abnormal uterine bleeding.First of all, a 4 mm diameter hysteroscope was used to perform a diagnostic hysteroscopy. Between the 20^th and 25^th day of their menstrual cycle, patients were booked for blind endometrial sampling and chromohysteroscopy directed biopsies. Results: Focal staining had higher sensitivity, specificity and accuracy 65.5%, 95% and 77.6% respectively, for detection of endometrial pathologies compared with diffuse staining. Focal dark pattern was significantly associated with, submucous myoma, endometrial hyperplasia, necrotic mass, endometritis, simple and complex endometrial hyperplasia with atypia and endometrial carcinoma. Conclusion: The diagnostic precision of traditional hysteroscopy is enhanced with chromohysteroscopy. In cases of Abnormal Uterine Bleeding (AUB), it is a useful, affordable diagnostic for identifying endometrial diseases.
