Accuracy of Transvaginal Ultrasound in Prediction of Latency Period in Women with Preterm Premature Rupture of Membranes

Abstract

relabor rupture of membranes (PROM) refers to membranes rupture before the onset of uterine contractions (previously known as premature rupture of membranes); PPROM refers to PROM before 37+0 weeks of gestation. It is responsible for, or associated with, approximately one-third of preterm births and the single most common identifiable factor associated with preterm delivery. PPROM occurs in 3 percent of pregnancies approximately 0.5 percent of pregnancies <27 weeks, 1 percent of pregnancies 27 to 34 weeks, and 1 percent of pregnancies 34 to 37 weeks. The aim of our study is to assess the accuracy of cervical parameters measured by transvaginal sonography, that is posterior uterocervical angle, anterior uterocervical angle and cervical length, in prediction of latency period in women with preterm premature rupture of membranes. This study is a prospective cohort study, this study was conducted on 205 women with PPROM that are clinically confirmed by visualization of amniotic fluid through the cervical os during speculum examination. the study was conducted at Ain Shams university maternity hospital.
