Study on Application Value of Pelvic Floor Ultrasound in Functional Screening of Pelvic Floor in The Third Trimester of Pregnancy and Postpartum Period
Abstract
Purpose: To study the application value of pelvic floor ultrasound in functional screening of pelvic floor during the third trimester of pregnancy and postpartum period.
Data and Methods: From January 2018 to January 2019, 80 puerperas with vaginal delivery who were admitted in the Department of Obstetrics of the Hospital were selected as study objects. Three-dimensional ultrasonography of pelvic floor was performed to measure the left and right diameter, anteroposterior diameter and area of levator ani muscle tear in the third trimester of pregnancy and 42-56 days after delivery, after Valsalva maneuver and in the state of anal contraction. The changes of levator ani muscle tear in the third trimester of pregnancy and postpartum puerperas were observed, and pelvic prolapse was evaluated.
Results: There were 10 cases of stress urinary incontinence in 80 puerperas, and no abnormalities were found in other tissues of pelvic floor. The postoperative urethral rotation angle, retrovesical angle and bladder neck mobility of puerperas with urethral funnels, cystocele and uterine prolapse were significantly greater than those in the third trimester of pregnancy (P < 0.05);In puerperas with abnormal shape of levator ani muscle, rupture of levator ani muscle or rupture anal sphincter, the left and right diameter, anteroposterior diameter and area of levator ani muscle tear in 42-56 days after delivery, in Valsalva maneuver and in the state of anal contraction were significantly higher than those of the third trimester of pregnancy (P < 0.05).
Conclusion: There are significant differences in the indexes of pelvic floor ultrasonography between postpartum period and the third trimester of pregnancy in puerperas with pelvic floor dysfunction. The pelvic floor ultrasonography can be used to screen the puerperas with pelvic floor dysfunction scientifically and effectively, which is of great significance in the diagnosis and early treatment of related diseases.
