Background: Cesareans were considered to the last option when vaginal delivery failed. In today’s world also females prefer vaginal delivery. The present study was done to identify the obstetrical parameters that influence the success of vaginal delivery in women with previous cesarean section.Materials & Methods: This study was conducted in the department of Gynaecology and Obstectics. It comprised of 120 females and equal number of primigravida in the control group. Pre-pregnancy BMI, indication of previous cesarean section, intra and postoperative complications of previous cesarean section, etc., was also recorded. Attempt at vaginal delivery was abandoned if there was any suspicion of scar dehiscence or signs of fetal distress or unsatisfactory progress of labor. The duration of labor and also the maternofetal outcomes were recorded for all patients.Results: Out of 240 subjects, 120 had previous cesarean while 120 comprised of control group. The difference was non- significant (P- 1). 13 women with BMI < 19.8 had a successful trial of labor. Out of 60 women who had a pre-pregnancy BMI within the range of 19.8–26, 45 delivered vaginally after a previous cesarean delivery while 15 of them underwent a repeat cesarean section. Out of 20 women with BMI (26-29), 10 delivered vaginally and 10 underwent cesarean. Out of 37 women with BMI >29, 12 delivered vaginally and 15 underwent cesarean. The difference was significant (P<0.05).  Among 10 women who failed their trial of VBAC, 2 had scar dehiscence, 5 developed post-op infection, and 3 had atonic PPH. Conclusion: Maternal pre-pregnancy BMI, non-recurring indications of previous cesarean section and spontaneous onset of labor are predictors of success of vaginal birth after previous cesarean section.
