Prospective Study For The Impact Of Different Delivery Factors On Postpartum Pelvic Floor Dysfunction

CHAPTER1Investgation of women with SUI after dilevery and analysis of its impact factorsObjectiveTo evaluate the assoeiated different influences to the Pelvic floor structure brought by different delivery metheds at the Post-natal early time through perineum vestibule three-dimensional ultrasonography, measuring the dynamic changes under diffenrent delivery methods to probe into the three-dimensional ultrasonography’s clinical application and to provide experimental data for the etiology and prevention of pelvic floor dysfunction.Methods1.To select1805women with singleton fetus with cephalic presentation metheds aged from18to44, with the gestational age between28weeks to42weeks as the research subject at random,to collect the clinical history and to dingnose the clinical symptom.2.To divide the above mentioned cases into normal vaginal delivery group and selective caesarean group according to the natural childbirth standards; to detect the data6-8weeks after the delivery. To detect the changes of the reproductive slit pores:antero posterior diameter (AP) and lateral diameter(LD) of the above mentioned women when at resting and maximal strength,posterior urethra-vesical angle(α)and the flexibility of bladder neek(θ),the distance between the pubic symphysis midpoint and bladder neek(D) and so on through perineum3D ultrasound convex probe.ResultsThere were significant differences statistically on the prevalence of anterior vaginal wall prolapse, posterior wall prolapse and uterine prolapse between elective cesarean section group and vaginal delivery group (P<0.05). Maternal age and infant birth weight were risk factors for pelvic organ prolapse(P<0.05), cesarean section was a protective factor (P<0.05)ConelusionsPelvic tissue damages under selective caesarean section is less than thatOf vaginal deliveris.Suggested that selective caesarean section have protective effect to pelvic structure.

To detect the changes of the reproductive slit pores:antero posterior diameter (AP) and lateral diameter(LD) of the above mentioned women when at resting and maximal strength,posterior urethra-vesical angle(a)and the flexibility of bladder neek(0),the distance between the pubic symphysis midpoint and bladder neek(D) and so on through perineum3D ultrasound convex probe.ResultsThere were significant differences statistically on the prevalence of anterior vaginal wall prolapse, posterior wall prolapse and uterine prolapse between elective cesarean section group and vaginal delivery group (P<0.05). Maternal age and infant birth weight were risk factors for pelvic organ prolapse(P<0.05), cesarean section was a protective factor (P<0.05)ConclusionsPelvic tissue damages under selective caesarean section is less than thatOf vaginal deliveris.Suggested that selective caesarean section have protective effect to pelvic structure.
