Role of Ultrasound in the Evaluation of Women with Obstetric Anal Sphincter Injuries: Narrative Review

Listen to this summary

This narrative review investigates the role of ultrasound, specifically pelvic floor ultrasound (PFUS) and endoanal ultrasound (EAUS), in the follow-up and management of women with obstetric anal sphincter injuries (OASI). The authors aim to determine how these imaging techniques can assess the success of repairs, identify residual defects, and guide therapeutic decisions and counseling for future pregnancies. The findings suggest that PFUS is beneficial for evaluating OASI outcomes and informing subsequent care.
