研究设计:

病例对照研究 

Study design:

Case-Control study 

研究目的:

研究一:测量并获得不同年龄段、不同产次的健康女性阴道前壁、后壁及侧壁的弹性数值正常参考值范围。 研究二:比较不同临床严重等级(基于标准化的临床指诊“金标准”)的阴道松症患者与健康对照组之间,其多模态超声参数的差异。  

Objectives of Study:

Study 1: To measure and establish normative reference ranges for the elasticity values of the anterior, posterior, and lateral vaginal walls in healthy women across different age groups and parity levels. Study 2: To compare multimodal ultrasound parameters between patients with varying clinical severity grades of vaginal laxity (determined by the standardized "gold standard" of digital pelvic examination) and healthy controls.

Inclusion criteria

排除标准:

研究一 1.现处于妊娠期、哺乳期或产后未满1 年 2.有产钳或胎吸助产史、有会阴撕裂伤史 3. 妇科检查证实存在II 度及以上的盆腔器官脱垂(POP-Q 分期>I 度) 4. 有中重度压力性尿失禁(SUI)或其他需治疗的尿失禁症状 5.有盆腔重大手术史(如子宫切除术、盆底重建术、抗尿失禁手术等) 6.有盆腔恶性肿瘤病史或放疗史 7. 患有已知的可能影响结缔组织或肌肉功能的全身性疾病(如Ehlers-Danlos 综合征、Marfan 综合征、系统性红斑狼疮、多发性硬化等) 8.检查时存在急性生殖道炎症 9.超声检查发现影响盆底结构的较大占位(如直径>5cm 的子宫肌瘤或卵巢囊 肿) 10.正在服用影响激素水平的药物(如口服避孕药、激素替代治疗等) 11.无法配合完成经阴道超声检查或Valsalva 动作者 研究二 1.妊娠期、哺乳期或产后未满1 年 2.重度盆腔器官脱垂(POP-Q分期 ≥ III度),因其本身即为明确的疾病实体, 会严重干扰测量 3.有盆底重建、抗尿失禁或阴道整形手术史 4.有盆腔恶性肿瘤或放疗史 5.影响结缔组织或神经肌肉功能的全身性疾病 6.急性生殖道炎症 7.无法配合完成问卷或超声检查者

Exclusion criteria:

Study 1 1.Currently pregnant, breastfeeding, or < 1 year postpartum 2.History of forceps or vacuum-assisted delivery, or perineal laceration 3. Pelvic examination showing pelvic organ prolapse >= stage II (POP-Q stage > I) 4. Moderate-to-severe stress urinary incontinence (SUI) or other bothersome urinary incontinence requiring treatment 5. Major pelvic surgery (e.g.hysterectomy, pelvic-floor reconstruction, anti-incontinence procedures) 6. History of pelvic malignancy or pelvic radiotherapy 7. Known systemic disorders affecting connective tissue or muscle function (e.g.Ehlers-Danlos syndrome, Marfan syndrome, systemic lupus erythematosus, multiple sclerosis) 8. Acute genital-tract infection at time of assessment 9. Imaging showing large pelvic masses that distort pelvic-floor anatomy (e.g. uterine fibroids or ovarian cysts > 5 cm) 10. Current use of hormonal medications affecting estrogen levels (e.g.oral contraceptives, hormone-replacement therapy) 11. Unable to tolerate trans-vaginal ultrasound or perform a Valsalva maneuver Study 2 1. Pregnancy, breastfeeding, or < 1 year postpartum 2. Severe pelvic organ prolapse (POP-Q stage >= III), as it constitutes a distinct disease entity that would severely confound measurements 3. Previous pelvic-floor reconstruction, anti-incontinence, or vaginal cosmetic surgery 4. History of pelvic malignancy or radiotherapy. 5. Systemic disorders affecting connective tissue or neuromuscular function. 6. Acute genital tract infection. 7. Inability to complete questionnaires or cooperate with ultrasound examination.
