基于超声盆腔器官活动度和肛提肌裂隙面积的盆腔器官脱垂诊断模型价值分析

目的 构建基于超声盆腔器官活动度和肛提肌裂隙面积（levator hiatus size,LHS）的盆腔器官脱垂诊断模型。方法 选择2021年3～12月于湖州市妇幼保健院就诊的126例疑似盆腔器官脱垂患者为研究对象,均接受盆腔器官脱垂量化系统（pelvic organ prolapse quantitation,POP-Q）检查和超声检查,以POP-Q检查结果为金标准将患者分为脱垂组（n=86）和非脱垂组（n=40）,记录两组患者的超声检查盆腔器官活动度和LHS,建立基于盆腔器官活动度和LHS的盆腔器官脱垂诊断模型;绘制受试者工作特征曲线（receiver operating characteristic curve,ROC曲线）评估模型诊断效能。结果 两组患者的超声检查结果显示脱垂组Valsalva动作的LHS及膀胱颈活动度（mobility of the bladder neck,BNM）、子宫颈活动度（mobility of the cervix,CM）和直肠壶腹活动度（mobility of the rectum ampulla,RAM）均显著增高（P<0.05）。Log...

Value analysis of the diagnostic model of pelvic organ prolapse based on ultrasound pelvic organ mobility and levator hiatus size

Objective To construct a diagnostic model of pelvic organ prolapse based on ultrasound pelvic organ mobility and levator hiatus size (LHS). Methods A total of 126 patients with suspected pelvic organ prolapse who were treated in Huzhou Maternal and Child Health Hospital from March to December 2021 were included as the research subjects. All patients underwent pelvic organ prolapse quantitation (POP-Q) examination and ultrasound examination. with the results of POP-Q examination as the gold standard, the patients were divided into prolapse group (n=86) and non-prolapse group (n=40), and the ultrasound examination of pelvic organ mobility and LHS were recorded in the two groups. A diagnostic model of pelvic organ prolapse based on levator fissure area; A receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic performance of the model. Results The ultrasonic examination results of the two groups showed that the LHS of Valsalva''s action, the mobility of the bladder neck (BNM), the mobility of the cervix (CM), and the mobility of the rectum ampulla (RAM) in the prolapse group were significantly increased (P<0.05). Logistic regression analysis showed that LHS, BNM, CM and RAM were all diagnostic factors for pelvic organ prolapse. The area under ROC curve of this established diagnostic model for diagnosing pelvic organ prolapse was 0.961, the sensitivity was 90.70% and the specificity was 97.50%. Conclusion The ultrasonic diagnostic model constructed based on pelvic organ activity and LHS has significant clinical value in the diagnosis of pelvic organ prolapse, and can be used for the diagnosis of clinical pelvic organ prolapse.
