Abstract
Objective To investigate the application value of transperineal pelvic floor 4-dimensional ultrasonography in the assessment of image feature of pelvic diaphragm hiatus of postpartum women.Methods Case group 1 was transperineal delivery group with 87 cases at 6-8 weeks after childbirth labor and followed-up after delivery in obstetric outpatient.Case group 2 was selective uterine-incision delivery group with 64 cases at 6-8 weeks after uterine-incision delivery and followed up after delivery in obstetric outpatient.Control group included 35 cases of benign gynecological diseases admitted in the hospital during the same period with no pregnancy or delivery history.Volumetric data was collected from 4-dimensional transperineal ultrasonography and the values of levator hiatal area ( LHA ) , levator hiatal lateral pathway (LHLP), levator hiatal anteroposterior pathway (LHAP) and levator-urethra gap (LUG) of three groups were measured during the resting state and maximum Valsalva.The differences among groups were analyzed statistically.Results At the resting state, the LHAP, LUG for right and left of case group 1 (5.06 ±0.88cm, 2.21 ±0.36cm, 2.22 ±0.36cm) and case group 2 (4.67 ±1.33cm, 2.08 ± 0.26cm, 2.08 ±0.26cm) were greater than those of the control group (4.55 ±0.87cm, 1.88 ±0.26 cm, 1.88 ±0.26 cm).At maximum Valsalva state, the LHAP, LHA, LUG for right and left of case group 1 (6.10 ±0.82cm, 23.27 ±4.85 cm2 , 2.54 ±0.44cm, 2.57 ±0.44cm) and case group 2 (5.48 ±1.46 cm, 20.86 ±4.75 cm2 , 2.42 ±0.33 cm, 2.42 ±0.33 cm) were greater than those of the control group (5.01 ±0.49cm, 17.82 ±3.32 cm2, 2.09 ±0.25cm, 2.09 ±0.25cm), and the differences were statistically significant (P <0.05).Conclusion Postpartum 4-dimensional ultrasonography can detect mild pelvic floor dysfunction (PFD) and injuries of puborectalis muscle which are not easily found by clinical examinations.It provides reference for clinical early assessment and preventing PFD, and it is worthy of promotion.关键词
