At present, two reference lines are used indistinctly: the pubococcygeal line (PCL) and the midpubic line (MPL). The H line is used for measuring pelvic floor relaxation, but not for staging POP. The aim of the study is to compare clinical staging of anterior pelvic prolapse with MRI staging, using the PCL, MPL and the H line as reference lines. Moreover, we want to analyze inter-rater reliability of each reference line. METHODS: We studied 42 women with POP symptoms using both physical examination and an MRI. We performed physical exam using the pelvic organ prolapse quantification (POP-Q) system. Two different observers calculated anterior POP using the three MRI reference lines. Agreement between MRI and clinical staging was estimated using Pearson Correlation for the quantitative measurements and weighted kappa for the stages. Inter-rater reliability was estimated using intraclass correlation coefficient (ICC). RESULTS: Agreement between physical exam and the H line was high by both observers (r= 0,86 and r= 0,76). However, agreement was lower using MPL (r= 0,76 and r= 0,65). The results of comparing MRI staging and physical examination were: κ = 0,618 and κ =0,602 for the H line, κ =0,273 and κ = 0,267 for MPL and κ = -0,105 and κ = -0,140 for PCL. The results of inter-rate reliability were: ICC of 0,968 for the H line, ICC of 0,788 for MPL and ICC of 0,737 for PCL. CONCLUSIONS: In our experience, anterior POP staging using MRI H line as a reference presents a better agreement with clinical staging than PCL or MPL. Furthermore, the H line has a better inter-rate reliability. Thus, the H line could be used as a reference line to measure anterior POP on MRI instead of the current lines.
