目的：采用磁共振成像（MRI）来确定骨盆器官脱垂（POP）分期系统与体格检查的解剖学相关性。此外，对标准POP分期系统进行分析，获得规范性数据，确定脱垂的危险因素。材料与方法：共有52名19 ~ 67岁的女性参与了我们的研究。在1.5特斯拉下进行骨盆MRI。阴道、膀胱、直肠均行混浊检查。受试者进行盆底收缩、放松和拉伸动作进行t1加权成像。数据分析采用单因素方差分析、Fisher精确检验和多项逻辑回归。结果：POP分期分为0 ~ IV期，0 ~ II期分别占56%、27%和17%。剖宫产次数（p = 0.64）和吸烟次数（p = 0.91）对POP分期无显著影响，但阴道分娩次数与分期有显著相关。阴道分娩1次的女性患I期疾病的风险增加（p = 0.018），而阴道分娩1次以上的女性患II期疾病的风险增加（p = 0.013）。在MRI 0期与I期或II期相比，膀胱下降有显著差异（p < 0.01）
Purpose: Magnetic resonance imaging (MRI) was performed to determine anatomical correlations with respect to physical examination using the Pelvic Organ Prolapse (POP) staging system. In addition, the standard POP staging system was analyzed to obtain normative data and determine any risk factors for prolapse.Materials and Methods: A total of 52 continent women 19 to 67 years old participated in our study. Pelvic MRI was performed at 1.5 Tesla. The vagina, bladder and rectum were opacified. Subjects performed pelvic floor contraction, relaxation and straining maneuvers for T1-weighted imaging. One-way analysis of variance, Fisher's exact test and multinomial logistic regression were used to analyze the data.Results: POP stage is quantified from 0 to IV. Stage was 0 to II in 56%, 27% and 17% of cases. POP stage was not significantly influenced by the number of cesarean sections (p = 0.64) or smoking (p = 0.91) but the number of vaginal deliveries significantly correlated with stage. Women with 1 vaginal delivery were at increased risk for a stage I condition (p = 0.018), whereas those with more than 1 were at increased risk for stage II (p 0.013). On MRI stages 0 versus I or II differed significantly in regard to bladder descent (p 0.01 and
