Pelvic organ prolapse is the descent of one or more of the anterior vaginal wall, posterior vaginal wall, the uterus (cervix), or the apex of the vagina (vaginal vault or cuff scar after hysterectomy). Prevalence increases with age. The cause of prolapse is multifactorial but is primarily associated with pregnancy and vaginal delivery, which lead to direct pelvic floor muscle and connective tissue injury. Hysterectomy, pelvic surgery, and conditions associated with sustained episodes of increased intra-abdominal pressure, including obesity, chronic cough, constipation, and repeated heavy lifting, also contribute to prolapse. Most patients with pelvic organ prolapse are asymptomatic. Symptoms become more bothersome as the bulge protrudes past the vaginal opening. Initial evaluation includes a history and systematic pelvic examination including assessment for urinary incontinence, bladder outlet obstruction, and fecal incontinence. Treatment options include observation, vaginal pessaries, and surgery. Most women can be successfully fit with a vaginal pessary. Available surgical options are reconstructive pelvic surgery with or without mesh augmentation and obliterative surgery.
盆腔器官脱垂是指阴道前壁、阴道后壁、子宫(宫颈)或阴道顶端(子宫切除术后的阴道穹窿或袖口瘢痕)中的一个或多个部位下降。患病率随年龄增长而增加。脱垂的原因是多因素的,但主要与妊娠和阴道分娩有关,这会导致盆底肌肉和结缔组织直接损伤。子宫切除术、盆腔手术以及与腹内压持续升高相关的疾病,包括肥胖、慢性咳嗽、便秘和反复重物搬运,也会导致脱垂。大多数盆腔器官脱垂患者无症状。随着膨出物突出超过阴道口,症状会变得更加困扰。初始评估包括病史和系统的盆腔检查,包括评估尿失禁、膀胱出口梗阻和大便失禁。治疗选择包括观察、阴道子宫托和手术。大多数女性可以成功佩戴阴道子宫托。现有的手术选择包括有或无网片增强的重建性盆腔手术和闭塞性手术。
