Abstract
Preterm delivery and subsequent preterm birth is a leading cause of perinatal morbidity and mortality and is a major problem in obstetrics. In preterm labor, labor progress is relatively faster than term labor, and the risk of changing of fetal presentation and prolapse of umbilical cord is higher than in term labor. These preconditions demand accurate, quick, objective, and repeatable method to assess labor progress. Transperineal ultrasound (TPUS) or translabial ultrasound (TLUS) clearly shows the presenting part of the fetus. Transperineal ultrasound meets these demands and is useful for the management of preterm delivery.
