Abstrakt: Purpose: The physical examination and pelvic imaging with MRI are often used in the pre-operative evaluation of pelvic organ prolapse. The objective of this study was to compare grading of prolapse on defecography phase of dynamic magnetic resonance imaging (dMRI) with physical examination (PE) grading using both the Pelvic Organ Prolapse Quantification (POP-Q) staging and Baden–Walker (BW) grading systems in the evaluation of pelvic organ prolapse (POP). Methods: We retrospectively reviewed the charts of 170 patients who underwent dMRI at our institution. BW grading and POP-Q staging were collected for anterior, apical, and posterior compartments, along with absolute dMRI values and overall grading of dMRI. For the overall grading/staging from dMRI, BW, and POP-Q, Spearman rho (ρ) was used to assess the correlation. The correlations between dMRI grading and POP-Q staging were compared to the correlations between dMRI grading and BW grading using Fisher's Z transformation. Results: A total of 54 patients were included. dMRI grading was not significantly correlated with BW grading for anterior, apical, and posterior compartment prolapse (p > 0.15). However, overall dMRI grading demonstrated a significant (p = 0.025) and positive correlation (ρ = 0.305) with the POP-Q staging system. dMRI grading for anterior compartment prolapse also demonstrated a positive correlation (p = 0.001, ρ = 0.436) with the POP-Q staging derived from measurement locations Aa and Ba. The overall dMRI grade is better correlated with POP-Q stage than with BW grade (p = 0.024). Conclusion: Overall and anterior compartment grading from dMRI demonstrated a significant and positive correlation with the overall POP-Q staging and anterior compartment POP-Q staging, respectively. The overall dMRI grade is better correlated with POP-Q staging than with BW grading. [ABSTRACT FROM AUTHOR]
