Abstract

Objective: To evaluate lower uterine segment thickness by transvaginal ultrasonography (TVS) and its correlation with obstetrical outcome and to derive a critical cut off above which vaginal delivery is safe. Method: A prospective study included 140 antenatal women with history of previous caesarean with gestational age 37-40 weeks in study group and 100 antenatal women without history of any uterine surgery with same profile in control group. Lower uterine segment (LUS) was scanned using TVS. All the women were followed till delivery and further divided into two groups for mode of delivery. Statistical analysis was done by applying chi square test.
Results: Overall vaginal birth after caesarean (VBAC) rate and VBAC success rate was observed as 48.57% and 65.38% respectively. The critical cut-off value for safe lower segment thickness derived from receiver operator characteristic curve was 2.5 mm.
Conclusion: TVS measured thickness of lower uterine segment allows assessment of scar complications and thus safer management of patient.

Key Words: Transvaginal ultrasonography, caesarean section, lower uterine segment, vaginal birth after caesarean
