Observation of Pelvic Floor Structure in Women Undergoing Second Natural Delivery Using Intelligent Pelvic Floor Ultrasound
Objective: To observe and study the pelvic floor structure of women undergoing second natural childbirth using intelligent pelvic floor ultrasound. Methods: Fifty pregnant women who completed second natural delivery in our hospital from April 2019 to April 2020 were selected as the experimental group, while 50 pregnant women who underwent first natural delivery during the same postpartum review were selected as the control group. Analyzing the test data of the two groups of patients, use two-dimensional ultrasound to observe whether there is pelvic floor organ prolapse and related parameter abnormalities in the two groups of pregnant women, and measure the movement of the bladder neck, urethral rotation angle, and posterior bladder angle of the pregnant women under Valsalva status; Real-time three-dimensional ultrasound was used to measure the area of the levator ani muscle hiatus under resting and Valsalva conditions, and to measure the pelvic floor muscle strength of the two groups of pregnant women. Results: There was no significant difference between the two groups in bladder neck movement, urethral rotation angle, and posterior bladder angle under Valsalva status (P>0.05). There was no statistically significant difference in the area of levator ani muscle hiatus between the two groups of parturients at rest [(14.00 ± 3.76) cm2 vs (14.51 ± 3.60) cm2] and Valsalva [(24.98 ± 326) cm2 vs (25.53 ± 3.40) cm2] (P>0.05); There was no significant difference in the incidence of pelvic floor organ prolapse and related abnormalities between the two groups (P>0.05); There was no statistically significant difference between the two groups in the unqualified rate of Class I (64.07% vs 69.00%) and Class II pelvic floor muscle strength (74.58% vs 78.00%) (P>0.05). Conclusion: The incidence of abnormal pelvic floor structure in women after second natural delivery is not significantly higher than that after first natural delivery, which provides imaging evidence for clinical guidance in selecting delivery methods and postpartum pelvic floor rehabilitation training for women after second natural delivery.
