Fore-lying of the Umbilical Cord after Urination: A Case Report

抄録

We present here a case of fore-lying of the umbilical cord. In this case, transvaginal sonography did not reveal the umbilical cord beyond the fetal head before maternal urination; however, 5 minute later, a fore-lying umbilical cord was revealed between the floating fetal head and the uterine cervix after urination. The present case indicates the importance of careful evaluation of preterm premature rupture of the membranes by means of transvaginal ultrasonography in predicting umbilical cord prolapse.
