Postpartum evaluation of the anal sphincter by transperineal three‐dimensional ultrasound in primiparous women after vaginal delivery and following surgical repair of third‐degree tears by the overlapping technique

Abstract

3DTUS is an accessible and promising method for postpartum sphincter evaluation, that is apparently well tolerated by patients. Reference data for sphincter anatomy representative of findings at transperineal ultrasound in primiparous women in the postpartum period have been established.
