Abstract: 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.
