Comparison of diagnostic values of transvaginal sonography with laparoscopic and histological results in the evaluation of uterosacral ligaments' involvement in endometriosis patients.

Background: Endometriosis is one of the most common gynecological disorders, which causes pain and reduces fertility. An accurate diagnostic technique would be helpful in the management of these patients preoperatively. The objective of this study was to do a comparative evaluation of uterosacral involvement in deep infiltrative endometriosis by transvaginal sonography (TVS) and laparoscopic biopsy.
