In order to explore the ability of vaginal ultrasound combined with bleeding pattern to predict factors related to abnormal uterine bleeding (AUB), a total of 205 patients with abnormal uterine bleeding were selected as experimental subjects. According to the corresponding diagnostic criteria, patients were divided into the endometrial polyp group (56 cases), endometrial hyperplasia and canceration group (84 cases), and normal cycle endometrial group (65 cases). The efficiency of the method was determined by comparing the prediction efficiency of the single/joint model. The results showed that there were statistically significant differences in the body mass index, dysmenorrhea, endometrial thickness, diabetes, hypertension, and polycystic ovary syndrome among the three groups, < 0.05. The sensitivity, specificity, positive predictive value, negative predictive value, and Youden index of endometrial polyp diagnosis were 86.89%, 88.12%, 83.54%, 90.11%, and 0.74, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and JordAn index in diagnosing endometrial hyperplasia and canceration were 96.71%, 98.40%, 96.54%, 98.24%, and 0.96, respectively. In summary, the body mass index, dysmenorrhea, endometrial thickness, diabetes, hypertension, and polycystic ovary syndrome were related factors, and the combination of vaginal ultrasound and bleeding pattern had a stronger predictive power for abnormal uterine bleeding.
为了探索阴道超声联合出血模式预测异常子宫出血（AUB）相关因素的能力，选取 205 例异常子宫出血患者作为实验对象。根据相应的诊断标准，将患者分为子宫内膜息肉组（56 例）、子宫内膜增生癌变组（84 例）和正常周期子宫内膜组（65 例）。通过比较单一/联合模型的预测效率来确定该方法的效率。结果显示，三组间的体质指数、痛经、子宫内膜厚度、糖尿病、高血压和多囊卵巢综合征存在统计学差异，<0.05。子宫内膜息肉诊断的灵敏度、特异度、阳性预测值、阴性预测值和 Youden 指数分别为 86.89%、88.12%、83.54%、90.11%和 0.74；子宫内膜增生癌变诊断的灵敏度、特异度、阳性预测值、阴性预测值和 JordAn 指数分别为 96.71%、98.40%、96.54%、98.24%和 0.96。综上所述，体质指数、痛经、子宫内膜厚度、糖尿病、高血压和多囊卵巢综合征是相关因素，阴道超声联合出血模式对异常子宫出血具有较强的预测能力。
