N2 - Purpose The aim of the study was to evaluate the utility of magnetic resonance imaging (MRI) pelvic landmark angles and lines in the assessment of apical vault prolapse. Methods Seventeen women were evaluated as part of a prospective surgical trial. Baseline data are presented as a pilot study of the utility of MRI in addition to this evaluation of 6 nulliparous volunteers without prolapse and 11 parous women with symptomatic ≥ stage II uterine prolapse. Each patient underwent assessment for pelvic organ prolapse quantification (POPQ) and pelvic MRI. Pelvic landmark angles and lines were measured. Mann-Whitney Rank sum test and Spearman's Rank order correlation test were used to assess agreement. Results Women with prolapse had a significantly larger h angle, g angle, and e angle at rest than those without prolapse. Correlation between apical vault descent was measured clinically by POPQ point C with MRI measurements: h angle (r = 0.61, p = 0.01), g angle (r = 0.64, p = 0.005), and e angle (r = 0.62, p = 0.007). Conclusion MRI measurements of pelvic landmark angles reliably differentiate between women with and without uterine prolapse and correlate best with POPQ point C.
