The aim of our study is to reveal the correlation between the posterior vaginal wall and apex in pelvic organ prolapse.
We retrospectively reviewed the records of all new patient visits to a urogynecology clinic between January 2013 and December 2015.
Four hundred five cases were enrolled in our study. When all POP stages were included, the Bp (pelvic organ prolapse quantification point) had a moderate correlation with the C (Pearson's r=0.419; P < 0.001). Cases where Bp was stage 3 and above presented strong positive correlations with C (Spearman's ρ=0.783; P < 0.001). Cases where C was stage 3 and above presented also strong positive correlations with Bp (Spearman's ρ=0.718; P < 0.001).
Posterior vaginal wall prolapse and apical prolapse were correlated with each other, and this correlation was more prominent as stage increased. Therefore, when admitting a patient suspected of posterior vaginal wall prolapse or apical prolapse, it is necessary to evaluate both conditions. Especially in cases more severe or equal to stage 3, it is a must to suspect both conditions as the 2 are strongly correlated.
