目的：探讨两种盆腔器官脱垂分度方法，标准盆腔器官脱垂定量（POP-Q）分度法与简化POP-Q分度系统（S-POP-Q）的相关性，明确S-POP-Q的应用价值。方法本研究是观察性研究。选取2010年1月至2014年1月就诊于宁夏医科大学总医院妇科门诊有盆底功能障碍症状和体征的患者256例，分别进行POP-Q分度和S-POP-Q分度。POP-Q分度法进行6个测量点（Aa、Ba、Ap、Bp、C、D）的测量，而S-POP-Q只进行4个测量点（Ba、Bp、C、D）的测量。用两种分度方法对盆腔器官整体、阴道前壁、阴道后壁、子宫、阴道后穹隆脱垂分别进行分度，比较两种分度方法的相关性。结果256例患者，进行POP-Q分度，盆腔器官的整体分度Ⅰ度20例（7.8%，20/256）、Ⅱ度94例（36.7%，94/256）、Ⅲ度112例（43.8%，112/256）、Ⅳ度30例（11.7%，30/256）；根据S-POP-Q进行分度，盆腔器官整体分度Ⅰ度21例（8.2%，21/256）、Ⅱ度92例（35.9%，92/256）、Ⅲ度112例（43.8%）和Ⅳ度31例（12.1%，31/256）；两种分度方法对盆腔器官整体分度的Kendall tau-b相关系数为0.81。Kendall tau-b相关性分析显示，两种分度方法对阴道前壁、阴道后壁、子宫、阴道后穹隆分度的相关系数分别为0.81、0.81、0.85、0.88。结论 S-POP-Q与POP-Q分度法对盆腔器官脱垂分度具有几乎完全的相关性。S-POP-Q是1种简易的评价盆腔器官脱垂的客观方法，适合于中国盆腔器官脱垂患者。%Objective To determine the association between simplified pelvic organ prolapse quantification system (S-POP-Q) and the standard pelvic organ prolapse quantification system (POP-Q) in describing pelvic organ prolapse. Methods This was an observational study. From Jan. 2010 to Jan. 2014, 256 subjects with pelvic floor disorder symptoms underwent two exams: a POP-Q exam and a S-POP-Q exam. For the S-POP-Q system, vaginal segments of the exam were defined using points Ba, Bp, C, and D. For the POP-Q system vaginal segments of the exam were defined using points Aa, Ba, Ap, Bp, C, and D. The inter-system consistency between the overall ordinal stages, the anterior vaginal wall stages, the posterior vaginal wall stages, the cervix stages, the posterior fornix or vaginal cuff stages from each two kind of exam were compared. Results The Kendall tau-b correlation coefficient for overall stage was 0.81, the Kendall tau-b correlation coefficients were 0.81, 0.81, 0.85, 0.88 for the anterior vaginal wall, for the posterior vaginal wall, for the cervix, for the posterior fornix or vaginal cuff, respectively. Conclusion There is almost perfect association between S-POP-Q and POP-Q in describing pelvic organ prolapse.
