Abstract

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.
