Frequency of Uterine Scar Dehiscence in Women with Previous One Cesarean Section

Background: Uterine scar dehiscence is a significant complication in women with a history of cesarean section, with implications for maternal and fetal health. Identifying risk factors and early detection is crucial for improving outcomes. While various demographic and clinical factors have been implicated, the association between maternal age, gestational age, parity, and hypertension with uterine scar dehiscence has not been fully explored in the local population. Objective: To determine the frequency of uterine scar dehiscence in women with previous one cesarean section. Study Design: Cross-sectional study. Duration and Place of Study: The study was conducted from January 2024 to July 2024 at a Mardan Medical Complex in Mardan, Pakistan. Methodology: A total of 109 women aged 18–40 years, with a singleton pregnancy of >32 weeks gestation and abdominal pain, were included. Ultrasound was performed by a senior consultant radiologist to assess uterine scar dehiscence, with clinical criteria based on scar tenderness and specific ultrasound findings. Results: The overall incidence of uterine scar dehiscence was 13.8%, with higher rates observed in women over 30 years (23.6%), those with a gestational age >39 weeks (47.6%), and women with higher parity (>4; 48%). Significant associations were found between uterine scar dehiscence and maternal age (p=0.004), gestational age (p<0.001), parity (p<0.001), and hypertension (p<0.001). No significant association was found with diabetes (p=0.701). Conclusion: The study concludes uterine scar dehiscence is a significant complication in women with prior cesarean sections, influenced by factors like age, parity, and hypertension, emphasizing the need for further research and protocols
