Abstract
Objective: We sought to compare bony pelvis dimensions at the level of pelvic support in women with and without pelvic organ prolapse (POP). Study Design: Pelvic floor dimensions of 42 white women with POP > 1 cm beyond the hymen were compared with 42 age- and parity-matched women with normal support. Bony landmarks relevant to connective tissue and levator attachments were identified on magnetic resonance imaging. Dimensions were independently measured by 2 examiners and averaged for each subject. Results: Measurements (in centimeters) for patients and control subjects were as follows: interspinous diameter, 11.2 ± 0.8 versus 11.1 ± 0.7, P = .19; anterior-posterior outlet diameter, 11.7 ± 0.7 versus 11.7 ± 0.8, P = .71; pubic symphysis to ischial spine left, 9.5 ± 0.5 versus 9.5 ± 0.4, P = .91; pubic symphysis to ischial spine right, 9.5 ± 0.4 versus 9.5 ± 0.5, P = .81; sacrococcygeal junction to ischial spine left, 7.0 ± 0.6 versus 7.0 ± 0.5, P = .54; and sacrococcygeal junction to ischial spine right, 7.0 ± 0.6 versus 6.9 ± 0.4, P = .32. Conclusion: Bony pelvis dimensions are similar at the level of the muscular pelvic floor in white women with and without POP.
