Abstract

Background: Due to a rise in the rates of primary caesarean section globally, repeat cesarean section has also become very common. Antenatal sonographic assessments of lower uterine segment may therefore increase safety for women undergoing a trial of labour by selecting women with lower risk of uterine rupture. Hence, this study is to find the correlation between ultrasonographic scar thickness and intraoperative uterine scar condition and feto-maternal outcome in patients with previous lower segment cesarean section (LSCS). Methods: Patients of previous caesarian section cases (38weeks to 42 weeks) attending to Navodaya Medical College Hospital and Research Centre, Raichur during the study period of 2021-2023 were included in the present study. Patients found to have scar thickness ≥2.5 mm and fulfilling the above mentioned criteria were allowed a trial of labor. Patients with a scar thickness < 2>0.05). The high-risk group had a lower period of gestation compared to the low-risk group. Notably, 32% of patients in the low-risk group had an inter-delivery interval of 2.5-3.5 years, while 60% of patients in the high-risk group had an inter-delivery interval of 1.5-2.5 years. NICU admission, required by 3% of newborns, reflects a broader spectrum of health issues that necessitate specialized care beyond what is typically provided in standard postnatal care. Conclusion: Sonographic assessment of LUS is an excellent, non-invasive and cost effective method for safely predicting scar integrity and can be recommended to be routinely incorporated in antenatal workup of a woman with previous caesarean section for making decision on the mode of delivery.
