Value Study of Diagnostic and Follow up Value of Four Dimensional Ultrasound for Pelvic Floor Function of Pregnant Women with Maternal Tract Lacerations
Objective To explore diagnostic and follow-up value of four-dimensional ultrasound for pelvic floor function of postpartum women with birth canal lacerations.Methods The paper chose 60 pregnant women with birth canal lacerations in our hospital from April 2021 to April 2023 as study group,and 60 pregnant women with cesarean section as control group.Two groups were treated with four dimensional ultrasound examinations at 42 days and 3 months postpartum.Results Study group had longer anterior posterior diameter of levator ani muscle hiatus under dynamic conditions(P<0.05),larger posterior angle,BND,and maximum area of urethra bladder(P<0.05),and larger bladder neck rotation angle and urethral rotation angle than control group(P<0.05),with lower proportion of Type I and Type Ⅲ in study group(P<0.05),while proportion of type Ⅱ in study group was higher(P<0.05).Detection rate of levator ani muscle tear,stress urinary incontinence,anterior rectal wall prolapse,and anterior vaginal wall prolapse was higher in study group(P<0.05).At the action state,anterior posterior diameter of the levator ani muscle hiatus was longer in study group(P<0.05),the posterior angle of urethra and bladder,BND,and minimum area was larger in study group(P<0.05),and urethral rotation angle was larger in study group(P<0.05).However,compared with 42 days postpartum,there was an improvement.Conclusion 4D ultrasound can achieve significant clinical value in diagnosing pelvic floor function of postpartum women with birth canal lacerations.Physicians can understand pelvic structure of puerpera,master pelvic floor muscle group function after delivery,and provide favorable reference data for clinical diagnosis of postpartum pelvic floor dysfunction,which has high clinical application value.
