Abstract |
OBJECTIVE To evaluate pregnancy associated change in width of the symphysis pubis. MATERIALS AND METHODS: 497 women were evaluated from Jan. 2000 to Dec. 2000. They were non-pregnant, pregnant and postpartum state without complaning of pelvis pain. Ultrasonographic measurements of the width of the symphysis pubis were performed. RESULTS: The population study shows 29.3 year-old as the mean age., gravid 2 and parity 0.6 . They consist of non-pregnant(n=36), first trimester(n=79), second trimester(n=118), third trimester(n=94), postpartum 4 weeks(n=84) and postpartum 8 weeks(n=86) women. The width of symphyseal joint was 3.93+0.05 mm(0.8-8.8 mm) among the total population, 3.20+0.17 mm in non-pregnant, 3.76+0.14 mm in first trimester, 3.95+0.10 mm in second trimester, 4.72+0.15 mm in third trimester, 3.98+0.12 mm in postpartum 4 weeks, 3.37+0.12 mm in postpartum 8 weeks women. The difference of the symphyseal joint width is statistically significant between non-pregnant and pregnant women(P=0.00). However the width of symphyseal joint were recovered until postpartum 8 weeks. There was no statistical difference of the width between first and second trimester,however significant difference between third trimester and before(P=0.00). The equation of regression ananlysis in the width of symphyseal joint was Y=3.25+0.04 x Gestation weeks during pregnancy(P>0.05). CONCLUSION: The width of the symphyseal joint had increased as gestational week advanced, and recovered until postpartum 8 weeks in pregnant women not complaining of pelvic pain. |
