Description for medicine or protocol of treatment in detail:

 

纳入标准:

(1) 既往接受过使用网片的盆底重建手术,距离上次使用网片的盆底重建术的手术时间>1年; (2)试验组的入组标准:试验组患者需临床诊断为网片暴露,且此次住院手术指征为网片暴露,网片暴露定义为通过阴道上皮可见至少2 mm的网片。所有受试者的网片必须是从前盆腔/阴道顶端植入的网片。 对照组入组标准:对照组的患者未发生网片暴露,不符合网片暴露的诊断,患者因其他盆底疾病入院拟计划手术切除全部/部分网片,且主要手术指征为其他盆底疾病,如尿失禁、子宫切除术后穹隆脱垂等。所有受试者的网片必须是从前盆腔/阴道顶端植入的网片。 (3)自愿加入本研究,并签署知情同意书; (4)年龄范围在40-80岁。

Inclusion criteria

(1) Previous pelvic floor reconstruction with mesh and >1 year from the last pelvic floor reconstruction with mesh procedure; (2) Enrollment criteria for the test group: patients in the test group were required to have a clinical diagnosis of mesh exposure, with mesh exposure defined as mesh visible through the vaginal epithelium for at least 2 mm. The mesh in all subjects must be a mesh implanted from the anterior pelvic/vaginal apex. Inclusion criteria for the control group: patients in the control group did not have mesh exposure, did not meet the diagnosis of mesh exposure, patients were admitted to the hospital for other pelvic floor disorders with a proposed plan for surgical removal of all/part of the mesh, and the primary surgical indication was other pelvic floor disorders such as urinary incontinence and post hysterectomy vault prolapse. All subjects must have mesh implanted from the anterior pelvic/vaginal apex. (3) Voluntary enrollment in the study with signed informed consent; (4) Age range of 40-80 years.

排除标准:

(1)严重的内科合并症,无法耐受手术者; (2)网片发生肠道或膀胱侵蚀; (3)炎症急性发作期,如发热、阴道壁脓肿、阴道溃疡; (4)患者正在接受慢性免疫抑制治疗,或患有自身免疫性疾病; (5)有阴道、宫颈或子宫内膜恶性病变。

Exclusion criteria:

(1) Severe medical comorbidities that preclude tolerating surgery; (2) Bowel or bladder erosion of the mesh; (3) Acute episodes of inflammation, such as fever, vaginal wall abscesses, and vaginal ulcers; (4) Patients undergoing chronic immunosuppressive therapy or suffering from autoimmune diseases; (5) The presence of malignant lesions of the vagina, cervix, or endometrium.
