This study aimed to assess success rate and factors associated with success of vaginal birth after one lower uterine segment transverse cesarean section delivery in SPHMMC Addis Ababa, Ethiopia, 2025. Objectives: The main objective of this research is to identify success rate and factors associated with vaginal birth after cesarean section in whom previously had one lower uterine segment transverse cesarean section from JANUARY 1 2023 DECEMBER 31 2023 at SPHMMC, Addis Ababa, Ethiopia. Methodology: Hospital based cross-sectional study will be conducted from 1st may to 31 June 2025. After the minimum sample size is determined using the single population proportion formula and assuming the margin of error to be 5%, with 95% level of significance and adding a 5% none response rate, the sample size will become 216. By using a standardized pre-tested questionnaire, data will be collected and entered using kobotoolbox for analysis and bivariate and a multivariate logistic regression analysis will be conducted to see association of the variables and control confounders.
