Predicting obstetric anal sphincter injuries (OASIS) in patients who undergo vaginal birth after cesarean section (VBAC).

Women with a history of prior cesarean section must weigh the numerous potential risks and benefits of elective repeat cesarean section or trial of labor (TOLAC). One important risk of vaginal delivery is obstetric anal sphincter injury (OASIS), and it occurs at higher rates among women undergoing vaginal birth after cesarean (VBAC). However, the risk of OASIS is not routinely included in TOLAC counseling and there is no tool available to risk stratify OASIS among women undergoing VBAC.
