Impact Of Pregnancy And Childbirth On Function Of The Pelvic Floor By Pelvic Ultrasound

Part1ObjectiveTo discuss the impact of pregnancy and different ways of childbirth on pelvicfloor anatomy and relationship between the change of pelvic floor anatomy and pelvicfloor functional disorder with perineum two-dimensional ultrasound.Research method1.150cases of women aged20-37were selected as research objects and dividedinto research group (50cases of childless women) and case group (100cases ofwomen with child). According to the way of childbirth, case group was furtherdivided into normal vaginal childbirth group (case group1:50cases) and selectivecesarean section group (case group2:50cases). According to the presence or absenceof stress urinary incontinence, the women with child were divided into non stressurinary incontinence group (case group3:50cases) and stress urinary incontinencegroup (case group4:50cases)2. GE E8cavity cubage probe was used to obtain the two-dimensional mediansagittal section of anterior pelvic floor under different state in quiescent condition andlargest Valsalva action. bladder neck at the lower edge of the pubic symphysisdistance (BSD), bladder neck down distance (BND), the bladder inside the mouth,bladder and urethra posterior horn (β), detrusor thickness (DT), angle of bladder walland standing vertical (γ)were observed and the data of all groups were compared andanalyzed.Results1.150cases of childbearing women aged20-37years were randomly selected asresearch object to collect clinical history data. They all completed valsalva maneuververy well. 2. Under quiescent condition, the difference in BSD, β and DT values betweencontrol group and case group, and between all cases groups were not statisticallysignificant.3. When making the biggest valsalva maneuver, except β, the difference in BNDand γ between control group and case group, and between all cases groups werestatistically significant.Conclusions1. Under quiescent condition, although there is no statistically significantdifference, the difference of data showed that pregnancy itself changes pelvic flooranatomy due to physiological change.2. When making the biggest Valsalva maneuve, the sonographic findings andrelated parameters were statistically significantly different between the case groupand control group, showing pregnancy and childbirth have damages on pelvic floor tosome degree. Statistical significance indicate that the change of pelvic anatomycaused by childbirth might lead to stress urinary incontinence (SUI).3. Two-dimensional ultrasonic measurement of various values can reflect thechange of pelvic cavity viscera anatomical structure, which is an effective method toevaluate pelvic organ prolapse.Part2ObjectiveTo observe the impact of pregnancy and different ways of childbirth on pelvicfloor pelvic floor ceasma area and pregnancy on force of pelvic floor anatomy basedon perineum three-dimensional ultrasound observation and measurement of pelviccavity viscera.Research method1.150cases of women aged20-37years were selected as research object anddivided into research group (50cases of childless women) and case group (100cases of women with child). According to the way of childbirth, case group was furtherdivided into normal vaginal childbirth group(case group1:50cases) and cesareansection group (case group2:50cases).2. GE E8cavity cubage probe was used to obtain the three-dimensional image ofpelvic floor ceasma under different state of quiescent condition and anal maneuver.Pelvic floor levator hiatus anteroposterior diameter (LH-A), transverse diameter (LR),pelvic floor hiatus area (HA) and visceral muscle thickness (C) were measured andthe value of all groups were analysised.Results1.150cases of childbearing women aged20-37years were randomly selected asresearch object to collect clinical history data. They all completed contraction analmaneuver very well.2. Under quiescent condition, except c, the difference in LH-A, LR, HA and Cbetween control group and case group, and between case group1and case group2were not statistically significant.3. Under the strongest contraction anal maneuver, LH-A, LR, HA and C valuesbetween control group and case group, and between case group1and case group2were statistically significantly different.Conclusions1. Both vaginal delivery and selective cesarean delivery have impact on pelvicfloor ceasma.2. Compared with vaginal delivery, the impact of selective cesarean delivery isweaker. The statistical significance of the largest contraction anal maneuver showsselective cesarean delivery may protect pelvic floor muscles.3. Perineal three-dimensional reconstruction technology can show pelvic floorstructure, so it is a reliable imaging method to observe female pelvic floor.
