Official Title: Sonographic Assessment of Myometrial Thickness as a Predictor for the Latency Interval in Women With Preterm Premature Rupture of Membranes

Brief Summary:

100 women divided into 3 groups:

  • Group I: included 50 women with preterm premature rupture of membranes (PPROM, n=50) with gestational age from 24 to 34 weeks.
  • Group II: included 25 term non-labor control (T-CTR, n=25) with gestational age from 37 to 41 weeks.

  • Group III: included 25 preterm non-labor control (P-CTR, n=25) with gestational age from 24 to 34 weeks.The myometrial thickness at 4 different sites9:

    a) The lower uterine segment (LUS): 2cm above the reflection of the full urinary bladder (b)The anterior wall: 1cm above the maternal umbilicus. (c)Fundus: by placing the scan probe perpendicularly above the uterine fundus so that the entire curvature of the uterus was visualized.

    (d)The posterior wall: through using the maternal abdominal aortic pulsation as an anatomic marker.

At least 3 measurements were obtained at each site and averaged. The latency interval is determined in each of the 3 groups.
