Abstract:
Objective:To use the perineum four-dimensional pelvic ultrasound stereo imaging for detecting injury situation of pelvic diaphragm hiatus and anal levator ani muscle. Understand abnormal classification of pelvic floor muscle. investigate the application of four-dimensional pelvic ultrasound stereo imaging in pelvic floor dysfunction (PFD) for primipara in order to provide more accurate data for clinical practice.Methods: 270 primiparas with pelvic floor dysfunction were divided into the vaginal delivery group (135 cases) and selective cesarean group (135 cases) as random number table; pelvic floor muscle strength, longitudinal diameter, transverse diameter, area of pelvic diaphragm hiatus and thickness of the anus levator were detected by the perineum four-dimensional pelvic ultrasound stereo imaging, respectively, and then to compare differences between the two groups. Results: In 270 cases, 162 cases (60%) were abnormalities in pelvic floor muscle strength, and 189 cases (70%) were abnormalities in vaginal pressure; the results of pelvic floor muscles fatigue grade situation revealed: 127 cases were abnormal muscle fiber strength ofⅠtype (47%), 30 patients were abnormal muscle fiber strength ofⅡ type (11%). There were no significant differences between the two groups in the abnormal rate of pelvic floor muscle strength, vaginal pressure and muscle fiber strength. Longitudinal diameter, transverse diameter and area of pelvic diaphragm hiatus in the vaginal delivery group were higher than that in the selective cesarean group, while thickness of anal levator were thinner than that in the selective cesarean group with significant differences (t=3.730,t=3.467, t=3.826,t=1.809;P<0.05).Conclusions: The perineum four-dimensional ultrasound diagnosis can intuitively and clearly show morphological characteristics of female pelvic diaphragm hiatus, therefore, it can quickly finish diagnosis, and provide the basis for clinical diagnosis and treatment evaluation of postpartum PFD.
