Abstract
Prior CS is a significant risk factor for OASIS at the first vaginal delivery. This suggests that relative fetopelvic disproportion leading to CS for a first delivery also predisposes to OASIS at a first vaginal delivery since 40 % of the increased incidence of OASIS risk was explained by birthweight and 4 % by maternal height.
