This document discusses a calculator for counseling women considering a trial of labor after cesarean (TOLAC) or vaginal birth after cesarean (VBAC). It provides a link to a website that contains a calculator to estimate a VBAC success rate based on factors like interdelivery interval and estimated fetal weight. The model was developed specifically for term singleton pregnancies with a prior low transverse cesarean delivery and cephalic presentation. The calculator may help with patient education and counseling for those considering a TOLAC at term.
