Obstetric anal sphincter injuries(OASIS) are associated with significant maternal morbidity including perineal pain, dyspareunia(painful sexual intercourse) and anal incontinence, which can lead to psychological and physical sequelae. The prevention, early diagnosis and repair of scathing anal sphincter are very beneficial to postpartum women which they can improve their life quality. So, one examination with accurancy and acceptance is very necessary for patient to assess anal sphincter. On clinic, the transperineal 3D-US imaging has become a portable, effective and relatively inexpensive modality to evaluate the anatomic integrity of the muscles of the anal sphincter.
