Aims and objectives: The aim of the study was to evaluate the role of sonographic measurement of myometrial thickness (MT) for the prediction of latency interval in women with preterm premature rupture of membranes (PPROM) at different periods of gestation between 28 and 34 weeks and to compare it with gestation-matched healthy antenatal women.
Materials and methods: Ultrasonographic (USG) MT at different gestations were measured at anterior, fundal, posterior, and lower uterine segment (LUS) in both the groups and its correlation with latency interval compared.
Results: One hundred and twenty women were enrolled for the study (90 women with rupture of membranes (ROM) and 30 healthy gestation-matched controls) between 28 and 34 weeks. Women with PPROM and preterm labor had a statistically significant difference in fundal and anterior MT, and no significant difference was observed in posterior and lower uterine segment (LUS) thickness. Women with PPROM having mean MT cutoffs of fundal 7.2087 ± 1.10324 standard deviation (SD) and anterior 7.4 ± 0.676 SD would deliver within 1 week, whereas those cutoffs of fundal 10.5200 ± 0.47430 SD and anterior 9.25 ± 1.030 SD would deliver after 2 weeks.
Conclusion: A significant relationship exists between anterior and fundal MT and latency interval in PPROM (28–34 weeks).
