title: An observational study of various predictors of success of vaginal delivery following a previous cesarean section.
abstract: OBJECTIVE
  To study the various predictors of success for vaginal birth after cesarean (VBAC) and to study the maternal and fetal outcomes in them and their comparison with control group.
  
  
  METHODS
  This prospective observational study included 100 women with previous cesarean section in the study group and 100 primigravidas in the control group. Various predictors for success of VBAC were analyzed and maternal and fetal outcomes were compared with the control group using student t test, Pearson χ (2) test, and Mann-Whitney U test.
  
  
  RESULTS
  Of 100 women with prior cesarean Sect. 65 had successful trial of labor, while 35 underwent a repeat cesarean section. Maternal complications in the previous CS group were 15 % as compared to only 2 % in the control group (p < 0.001).
  
  
  CONCLUSIONS
  Maternal pre-pregnancy BMI, non-recurring indications of previous cesarean section, good Bishop's score at the time of admission, spontaneous onset of labor, and neonatal birth weight were significantly related to high chances of success of vaginal birth after previous cesarean section. Maternal complications were more common in study group, but the fetal outcomes were similar.
