FREQUENCY OF ENDOMETRIOSIS FINDINGS IN TRANSVAGINAL ULTRASOUND WITH INTESTINAL PREPARATION ACCORDING TO THE UBESS AND ASRM CLASSIFICATION

Abstract

Introduction: Endometriosis is characterized by the presence of endometrial tissue outside the uterus. The gold standard test to establish its diagnosis is laparoscopy, but transvaginal ultrasound has become the main diagnostic tool in the diagnosis of endometriosis. Objectives: To analyze the frequency of endometriosis findings on transvaginal ultrasound with bowel preparation according to the Ultrasound‐ Based Endometriosis Staging System (UBESS) and American Society for Reproductive Medicine (ASRM) classification. Methods: This is a cross-sectional, descriptive, retrospective and quantitative study, carried out at Clínica Fértile, where 413 examinations were analyzed. transvaginal ultrasound with bowel preparation in women aged 18 to 60 years, performed from January 2020 to December 31, 2020 in Goiânia, Goiás. Results: In total, 413 reports were evaluated, 272 normal and 141 with endometrial changes, representing 34% changes. The average age was 34 years old, ranging from 18 to 59 years old. In the studied group, in relation to ASRM stages, the frequency was higher in severe cases of endometriosis with 36%, whereas in UBESS the frequency was higher in stage II with 50% of cases. In both classifications, the most affected age group were women between 20 and 40 years old, as they are still of reproductive age. Conclusion: The frequency of alterations is 34%. ASRM the frequency was higher in severe cases of endometriosis with 36%. UBESS frequency was higher in stage II with 50% of cases. In both classifications, the most affected age group were women between 20 and 40 years old, as they are still of reproductive age.
