Objectives: To assess the incidence and risk factors of scar dehiscence.

Methodology: This was a prospective observational study where a total of 210 patients were involved over a period of six months (May 2020 to November 2020) who came to Sandeman Provincial Hospital, BUMHS gynaecology unit 1. The parturient were above the age of 18 and had previous uncomplicated lower segment caesarean sections. Patients with previous classical caesarean section and ruptured uterus diagnosed pre or intra-operatively were excluded from the study. Sampling technique: Non-probability convenience sampling technique will be used.

Results: In this study, the mean age of the patients was 31.57 ± 4.26 years, the mean gestational age was 34.43± 4.45 weeks. The incidence of scar dehiscence was observed in 47 patients.

Conclusion: Uterine Scar Dehiscence is one of the factors that increases fetal and maternal morbidity and mortality rate. Its incidence is found to be related with C-sections, inadequately short intra-pregnancy time interval, preterm delivery, VBAC and trial labour. In this study, the incidence of scar dehiscence was 22.38%.
