Introduction and hypothesis

The objective of this study is to determine the association between the POPQ and a simplified version of the POPQ.


This was an observational study. The subjects with pelvic floor disorder symptoms underwent two exams: a POPQ exam and a simplified POPQ. To compare with the simplified POPQ, vaginal segments of the POPQ exam were defined using points Ba, Bp, C, and D. Primary outcome was the association between the overall ordinal stages from each exam.


One hundred forty-three subjects with mean age of 56 +/− 13 years. Twenty three subjects were status post-hysterectomy. The Kendall's tau-b statistic for overall stage was 0.80, for the anterior vaginal wall the Kendall's tau-b was 0.71, for the posterior vaginal wall segment the Kendall's tau-b was 0.71, for the cervix the Kendall's tau-b was 0.88, for the posterior fornix/vaginal cuff the Kendall's tau-b was 0.85.


There is substantial association between the POPQ and a simplified version of the POPQ.
