The Application Of Vaginal Tactile Imaging In Postpartum Pelvic Floor Function And Pregnancy-related Sterss Urinary Incontinence

Background: Pregnancy and delivery are risk factors affecting pelvic floor function,and the new technology,vaginal tactile imaging,can be used for the further research of postpartum pelvic floor condition and pregnancy-related stress urinary incontinence.Objective: To explore the effect of delivery mode on the recent postpartum pelvic floor condition and the characteristics of pelvic floor function in pregnancy-related SUI patients with VTI.Methods: From October 2018 to January 2020,262 women were selected from the obstetrics and gynecology department of Shanghai Jiaotong University Affiliated Sixth People’s Hospital for postpartum follow-up and treatment.SPSS 22.0 was used for data analysis.Independent sample t Test was used for measurement data,and chi-square Test was used for categorical data.Results: The mean value of the maximum elastic gradient of the anterior and posterior vaginal walls,the maximum pressure of the anterior and posterior vaginal walls during fast contraction,and the maximum pressure of the anterior and posterior vaginal walls during sustained contraction were significantly higher in the cesarean section group(n=88)than in the vaginal delivery group(n=128)(P < 0.05).For patients with SUI(n=64),the pressure on the anterior vaginal wall where is 3cm deeper from the vaginal orifice is 107.0± 74.8mm Hg in fast contraction and 99.3±67.2mm Hg in sustained contraction,while non-SUI(n=152)group is143.2± 94.4mm Hg in fast contraction and 138.4± 94.5mm Hg in sustained contraction(P < 0.05).Conclusion: he elasticity and contractility vaginal wall were significantly reduced after delivery,and the pelvic floor function of those who take cesarean section is generally better than that of vaginal delivery in a short period.There was no significant difference between those of cesarean delivery and without childbirth in some parameters,indicating that cesarean section contribute to better pelvic floor function.The maximum pressure of at the anterior vaginal wall 3cm from the vaginal orifice on postpartum women with SUI was less than non-SUI women,and there was a statistical difference between fast and sustained contraction,which may be related to the injury of the muscles and connective tissues in the middle of the urethra.
