Objectives: The anatomical and dynamic structure of the pelvis is an important element in delivery. During pregnancy, high progestorene and relaxin
levels produce physiological ligament relaxation on the pelvis. The suitability of pelvic diameters is important in performing vaginal delivery. In this study we aimed to determine whether there is any change in symphysis pubis width during delivery.
Methods: This prospective observational study included 108
pregnant women who were at 37-42 weeks of gestation with cephalic presentation
of a singleton pregnancy and were hospitalized for delivery. Symphysis pubis
width was measured by transabdominal ultrasonography in each woman during the
latent phase while cervical dilatation was 2 cm, the active phase while
cervical dilatation was 6 cm and the second stage within one hour of complete
cervical dilatation.
Results: Symphysis pubis width value significantly increased
as the labor progressed. Namely, the mean symphysis pubis width value measured
in the latent phase was the smallest while the mean value in the second stage
of the labor was the highest. In addition, birth weight of newborn was
positively correlated each of symphysis pubis width values measured at all
three different times.
Conclusion:
Symphysis pubis width increases as labor progresses. And this increase advances
as the weight of newborn increases.
