| 目的探究剪切波弹性成像(SWE)联合灰阶超声评估分娩方式对初产妇膀胱颈弹性、形态的影响。 方法回顾性选择产后6～8周初产妇106例,按分娩方式分为剖宫产组(n＝48)和阴道分娩组(n＝58)；按压力性尿失禁(SUI)发生情况分为SUI组(n＝53)和非SUI组(n＝53)。选择同期曾妊娠但未成功分娩者50例为对照组。另选所有女性均行SWE结合灰阶超声检查评价膀胱颈变化,比较各组膀胱颈弹性、形态超声参数,比较剖宫产组与阴道分娩组的盆底肌功能障碍发生率。 结果膀胱颈前、后唇杨氏模量对照组＞剖宫产组＞阴道分娩组,非SUI组＞SUI组(P＜0.05)。阴道分娩组Valsalva状态下膀胱颈活动度、倾斜角均对照组＜剖宫产组＜阴道分娩组(P＜0.05)。阴道分娩组SUI、膀胱膨出、子宫脱垂、阴道前壁脱垂的发生率均高于剖宫产组(P＜0.05)。 结论应用SWE结合灰阶超声评估发现,不同分娩方式对初产妇产后膀胱颈形态影响小,对膀胱颈弹性影响大,且以经阴道分娩产妇的损害更为严重。 |

| AimTo investigate the impact of delivery modes on bladder neck elasticity and morphology in primiparas using shear wave elastography (SWE) combined with grayscale ultrasound. MethodsA retrospective analysis based on 106 primiparas at 6－8 weeks postpartum was conducted. The subjects were divided into cesarean section group (n＝48) and vaginal delivery group (n＝58), and further categorized into stress urinary incontinence (SUI) group (n＝53) and non-SUI group (n＝53). Additionally, 50 subjects who had been pregnant but did not deliver successfully were selected as the control group. All participants underwent SWE and grayscale ultrasound to evaluate bladder neck changes. Ultrasonic parameters of bladder neck elasticity and morphology were compared among groups, and the incidence of pelvic floor dysfunction was compared between the cesarean section and vaginal delivery groups. ResultsThe Young's modulus of the anterior and posterior bladder neck lips was in an order of control group > cesarean section group > vaginal delivery group, non-SUI group > SUI group (P＜0.05). During Valsalva maneuver, bladder neck mobility and inclination angle were in an order of the control group < the cesarean section group < the vaginal delivery group (P＜0.05). The incidences of SUI, cystocele, uterine prolapse, and anterior vaginal wall prolapse were higher in the vaginal delivery group than those in the cesarean section group (P＜0.05). ConclusionBy combining SWE with grayscale ultrasound, the results demonstratethat different delivery modes have minimal impact on postpartum bladder neck morphology but significantly affect bladder neck elasticity, with vaginal delivery causing more severe impairment. |
