Abstract

Background: This retrospective observational study investigates the effect of birth spacing and timing of previous caesarean sections, on uterine scar integrity in post-caesarean pregnancies. Scar dehiscence is asymptomatic in 48% of patients and thus is a serious complication because if not predicted, it can lead to uterine rupture.


Materials and Methods:


The study conducted at the Government General Hospital, Eluru, has analysed 135 women with repeat C-sections using inpatient records and statistical analysis in SPSS version 16.0.


Results:


 Uterine scar dehiscence was identified in 47% of cases, with a significant association between short birth spacing (<2 years) and higher dehiscence rates (57.7%) compared to longer intervals (>2 years, 21.1%; p = 0.0001). No significant association was found with the number of prior C-sections or whether the prior delivery was elective or emergency. These findings highlight that inadequate birth spacing remains a critical risk factor for uterine scar dehiscence, underscoring the need for proper counselling on optimal birth spacing to reduce maternal morbidity in repeat caesarean sections.
