目的:研究剪切波弹性成像(Shear wave elastography, SWE)联合盆底超声检查评估产后压力性尿失禁(Postpartum stress urinary incontinence, PSUI)患者经生物反馈电刺激联合磁刺激治疗后膀胱颈变化。方法:选取2023年1月至2024年3月来我院产后康复科就诊的45例PSUI患者为研究对象,于分娩6周后行生物反馈电刺激联合磁刺激治疗,于治疗前后采用SWE联合盆底超声记录患者静息状态、Valsalva状态下膀胱颈前后唇杨氏模量值、膀胱颈前后唇厚度、膀胱颈移动度(Bladder neck descent, BND)、膀胱颈距耻骨联合后下缘距离(Bladder neck-symphyseal distance, BSD)、膀胱尿道后角(Posterior urethra vesical angle, PUVA)、尿道旋转角(Urethral rolation angle, URA)、肛提肌裂孔面积(Levator hiatus area, LHA)、尿道漏斗形成率。结果:治疗后膀胱颈前后唇厚度变化无显著性差异(P > 0.05),但治疗后膀胱颈前后唇杨氏模量值均显著高于治疗前(P P Objective: To investigate the changes in bladder neck in postpartum stress urinary incontinence (PSUI) patients treated with biofeedback electrical stimulation combined with magnetic stimulation using shear wave elastography (SWE) combined with pelvic floor ultrasound. Method: A total of 45 PSUI patients in our hospital from January 2023 to March 2024 were selected, Starting from 6 weeks postpartum, receiving biofeedback electrical stimulation combined with magnetic stimulation therapy. Before and after treatment, SWE combined with pelvic floor ultrasound was used to record the patient’s resting state, bladder neck anterior and posterior lip thickness in Valsalva state, Young’s modulus value of the anterior and posterior labia of the bladder neck, bladder neck mobility (BND), bladder neck-symphyseal distance (BSD), posterior urethrovesical angle (PUVA), urethral rotation angle (URA), levator hiatus area (LHA) and the formation rate of urethral funnel. Result: The thickness of bladder neck’s anterior lip and posterior
