Chapter 49: Vaginal, Uterine, and Ovarian Disorders

Amenorrhea, classified as primary or secondary, reflects disruption of the hypothalamic-pituitary-ovarian-uterine axis through mechanisms ranging from chromosomal abnormalities and anatomical malformations to neuroendocrine dysfunction triggered by stress, weight fluctuations, or intensive athletic training. Dysmenorrhea results from prostaglandin-mediated uterine contractions and ischemia during menstruation, with management centering on nonsteroidal anti-inflammatory agents and hormonal suppression. Endometriosis represents a chronic condition involving ectopic endometrial implantation, typically causing recurrent pelvic pain and dyspareunia with significant infertility implications, diagnosed definitively through laparoscopy and managed through analgesics, hormonal therapies including gonadotropin-releasing hormone analogs, or surgical intervention. Leiomyomas are benign smooth muscle neoplasms with notable epidemiological variation across racial and ethnic populations, presenting with abnormal uterine bleeding and pelvic pressure, confirmed through transvaginal ultrasonography and managed with medical or surgical approaches depending on fertility preservation goals. Cervical pathology stems predominantly from persistent infection with oncogenic human papillomavirus types, with screening protocols utilizing primary testing and Bethesda System categorization to identify precancerous and cancerous lesions requiring colposcopy, biopsy, or surgical ablation. Endometrial cancer, the most prevalent gynecological malignancy, develops primarily through unopposed estrogen exposure in postmenopausal populations, presenting with postmenopausal bleeding and requiring endometrial biopsy for diagnosis followed by hysterectomy with bilateral salpingo-oophorectomy. Ovarian cancer presents diagnostic challenges due to vague early symptoms and late-stage presentation, necessitating imaging and tumor markers combined with aggressive surgical cytoreduction and platinum-based chemotherapy regimens. Vulvodynia, characterized by idiopathic chronic vulvar pain, requires multidisciplinary management emphasizing pelvic floor rehabilitation and neuropathic pain pharmacotherapy.
