Uterine Cavity Abnormalities in Patients with Endometriosis in Alexandria: A Diagnostic Test Accuracy Study.

Endometriosis is strongly associated with infertility. Endometrial polyps are prevalent in infertile women and they have similar pathological characteristics to endometriosis, suggesting a possible association. Uterine malformations as uterine septum and hypoplastic uterus are also linked to endometriosis. Hysterosalpingogram and transvaginal ultrasonography are used to diagnose endometrial lesions. Hysteroscopy can detect small lesions that might be missed. Recently, 4D ultrasonography is being used, but which is superior has not been established yet. We aim to compare 4D ultrasonography to office hysteroscopy in evaluating uterine cavity in cases with endometriosis; also we aim at correlating these findings with the stage of endometriosis. 50 cases of endometriosis diagnosed by laparoscopy were randomly selected from El Shatby fertility clinic, Alexandria University, Egypt, with exclusion of cases with any previous intrauterine surgery or any hormonal treatment. Transvaginal 4D ultrasonography and office hysteroscopy were done. 4D ultrasonography agreed with office hysteroscopy in diagnosing abnormal uterine findings in 14 cases and four additional cases were diagnosed by hysteroscopy alone. Conclusion . Endometrial polyps, septate uterus, and hypoplastic uterus are more prevalent among infertile women who happen to have endometriosis. 4D ultrasonography and office hysteroscopy are equally successful in assessing the uterine cavity.
