Outcome Measures

Primary Outcomes (2)

  • sliding sign

    The probe was placed just above the transverse skin scar and the patient was asked to take a deep breath or cough in order for the uterus to be observed sliding caudally under the parietal peritoneum and fascia transversalis. Presence of the sliding sign was described "positive" when sliding of the uterus against the abdominal wall was observed. When no movement of the uterus under the fascia, the sliding sign was considered "negative".

    The study will end when a sufficient number of patients is reached.

  • Vesicouterin thickness

    The tissue between the uterus and bladder (vesicouterin thickness) was examined and mesasured.

    Approximately 6 months. The study will complete when required number of patients reached.

Model Details: Pregnant women aged 18-45 years with singleton, viable third-trimester (37 weeks of gestation or later) pregnancies with the history of at least one previous cesarean section were included in the study. The control group consisted of healthy pregnant women in the third trimester with similar demographic characteristics who underwent elective (planned) cesarean delivery and had no obstetric or medical comorbidities. The aim was to evaluate the relationship of the bladder to the uterus including vesicouterin thickness and sliding sign in term pregnancies with at least one previous cesarean section and compare to controls. The relationship of the bladder to the uterus, whether it was below or above the symphysis pubis, slidign sign and vesicouterin thickness were noted.
