Aims: To determine the frequency of patients with previous one Cesarean section who develop scar tenderness during trial of labour and frequency of Scar Dehiscence in patients with previous one Cesarean section who develop scar tenderness during trial of labour. Setting: Labour room, PGMI / Lahore General Hospital Duration of Study: January 2013 to December 2013 Results: In our study, mean age was calculated as 28.62 +/- 5.25 years, mean gestational age was calculated as 38.45 +/- 2.37 weeks, frequency of patients with previous one cesarean section who develop scar tenderness during trial of labour reveals 19(7.6%), frequency of scar dehiscence in patients with previous one cesarean section who develop scar tenderness during trial of labour was recorded in 2(10.53%). Conclusion: We concluded that the frequency of patients with previous one Cesarean section who develop scar tenderness during trial of labour are not remarkably higher and the trial of labour in these patients may continue confidently and thus decrease rising cesarean section rate in our population.
