Purpose: to determine the predictive value of trans-abdominal (TA) US in assessing thickness of lower uterine segment by measuring lower uterine segment (LUS) scar thickness at term in patient with previous CS. Patient and methods: This study was carried out as tool-assessment cross-sectional case study on pregnant females, who had previous cesarean section at 36-40W of gestation and planning for elective CS. LUS thickness measured by TAUS and measured by the surgeon after labour using a sterile vernier caliper. The sensitivity, specificity, positive and negative predicted values of the TAUS measurement was determined. Results: eighty nine women were studied at a mean gestational age of 38.5±0.59weeks. With cutoff value equal to or less than 2.4 mm , the sensitivity, specificity, positive and negative predicted values were 90%, 100%, 100%, and 98.7%, respectively. Conclusion: LUS measurement is a useful clinical tool in the prediction of scar integrity. It should be performed routinely in women who had a previous cesarean before labour. Key word: cesarean section(CS), lower uterine segment (LUS), trans-abdominal ultrasound (TAUS). scar thickness
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
