摘　　要：目的：通过磁共振成像（MRI）检查对盆腔器官脱垂（POP）患者进行分级,分别采用耻骨尾骨线（PCL）及耻骨中轴线（MPL）为参考线,探讨其与盆腔器官脱垂定量分期法（POP-Q）所得结果的相关性。方法收集 POP 患者32例,行动态 MRI 检查,以PCL及 MPL作为参考线进行分级,结果与POP-Q分级结果进行相关性比较。结果 MPL 作为参考线时,前、中盆腔 MRI分级与POP-Q分级一致性较好（前部κ=0.44,SE=0.13；中部κ=0.46,SE=0.12）,而后盆腔一致性一般（κ=0.23,SE=0.10）。而PCL作为参考线时,前、中、后盆腔与POP-Q分级的一致性均较差（前盆腔κ=0.07,SE =0.14；中盆腔κ=0.06,SE=0.05；后盆腔κ=-0.51,SE=0.09）。结论 MPL作为参考线,POP的 MRI分级与POP-Q分级一致性优于PCL。Objective To assess the correlation between magnetic resonance imaging （MRI）and clinical staging of pelvic organ prolapse （POP）by using pubococcygeal line （PCL）and midpubic line （MPL）respectively.And to determine which（MRI）reference line for staging pelvic organ prolapse had the highest agreement with clinical staging.Methods A retrospective study of 32 women with pelvic organ prolapse who underwent dynamic pelvic MRI from Jan 2013 to May 2013 was conducted.One radiologist staged descent on MRI for each pelvic compartment （anterior,middle,posterior）,using PCL and MPL lines.Agreement between MRI and clinical staging was estimated respectively.Results Thirty-two women were included.Agreement between clinical and MPL staging was morderate in the anterior （κ=0.44,SE=0.13）and middle compartment （κ=0.46,SE=0.12）,but fair in the posterior com-partment （κ=0.23,SE=0.10）.Agreement between clinical and PCL staging was poor in all compartments of pelvic.Conclusion MPL appeared more reliable and simple than the PCL for the evaluation of pelvic prolapse on MRI.
