The characteristics and the morphology of lower
segment of normal pregnant uterus were observed
in 40 normal fullterm pregnant women using
ultrasonography with regard to its diagnostic value
and clinical applicability_
As it is impossible to measure the exact thickness
of anterior wall of lower segment of uterus , the
interval of urinary bladder wall to fetal surface (B-F
interval) was measured using ultrasonography, and
minimum B-F interval was determined
The results were summarized as follows
1. In 40 normal fullterm pregnant women, mini•
mum B-F interval was 5. 4±1. 2mm.
2. In normal fullterm pregnant women, minimum
B-F interval showed a tendency to decrease as gesta'
tional period lengthened, but there was no statistical
3. In 24 primigravidas, minimum B-F interval was
5.5±1. 3mm and it showed a tendency to decrease as
gestational period lengthened. but there was no stat·
istical significance.
4. In 16 multigravidas, minimum B•F interval was
5. 2±1. 2mm and it also showed a tendency to deerease
as gestational period lengthened, but there was
no statistical significance
The above results suggest that ultrasonography is
a very useful objective and non-invasive diagnostic
tool in the measurement of the characteristics of lower
segment of pregnant uterus and the assessment of
progress and prognosis of labor.
