POP-Q, dynamic MR imaging, and perineal ultrasonography: do they agree in the quantification of female pelvic organ prolapse?
Open accessAbstract
INTRODUCTION AND HYPOTHESIS: This study evaluates the agreement in prolapse staging between clinical examination, dynamic magnetic resonance (MR), imaging and perineal ultrasonography. METHODS: Anatomical landmarks in the anterior, central, and posterior compartment were assessed in relation to three reference lines on dynamic MR imaging and one reference line on dynamic ultrasonography. These measurements were compared to the according POP-Q measurements. Agreement between the three methods was analyzed with Spearman's rank correlation coefficient (r(s)) and Bland and Altman plots. RESULTS: Correlations were good to moderate in the anterior compartment (r(s) range = 0.49; 0.70) and moderate to poor (r(s) range = -0.03; 0.49) in the central and posterior compartment. This finding was independent of the staging method and reference lines used. CONCLUSION: Pelvic organ prolapse staging with the use of POP-Q, dynamic MR imaging, and perineal ultrasonography only correlates in the anterior compartment.

Dynamic MRI has been used to assess prolapse through imaging, but studies suggest that when compared with physical examination there is good to moderate correlation only in the anterior compartment and imaging tends to overestimate the extent of the prolapse.

The Statistical evaluation and Results sections compare prolapse measurements across POP-Q, MR imaging, and ultrasonography; they do not report treatment-success rates. Searches for “19.2,” “97.2,” and treatment-success definitions found no passage supporting the claimed range. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
