Study on post-cesarean uterine cavity morphology using three-dimensional ultrasonography

Objective To investigate the post-cesarean uterine cavity morphology and its clinic value by the three-dimensional ultrasonography. Methods Altogether 278 cases were divided into two groups, including post-cesarean group(138 cases) and natural labor group(140 cases). The data of uterine cavity morphology were collected using three-dimensional ultrasonography from coronal section,and the data were compared between the two groups. Results The percentage of irregular and long triangle shape in post-cesarean group(45/138, 32.6%) was significantly higher than that of natural labor group(10/140,7.1%),there was significant difference(P﹤0.05). The transverse diameter of the post-cesarean group(2.78±0.56)cm was significantly shorter than that of natural labor group(3.07±0.72)cm,but the longitudinal diameter of the post-cesarean group(5.17±0.83)cm was greater than that of natural labor group(4.53±0.77)cm,there was significant difference(P﹤0.05). No significant difference was found in cervix diameter between the two groups. Conclusion The cesarean is the main reason for uterus cavity shape changing into long, narrow and irregular shape. Three-dimensional ultrasonography can accurately reflects the characteristics of uterine cavity morphology,providing valuable information and guide clinic.
