Relationships between pelvic organ prolapse (POP) staging and lower urinary tract symptoms (LUTS) are controversial. In this study, we evaluated correlations of POP staging with LUTS in different compartments.
From January 2016 to December 2017, 250 consecutive patients with urogynecologic complaints who were referred to our urodynamic unit were recruited into this study. Different stages of different compartments (anterior, central and posterior) of POPs according to IUGA and ICS terminology were re-grouped into four categories as stage 0, 1, 2, and 3 (including stage 4 because of a limited number of patients in stage 4). Pearson correlation coefficient and general linear regression were used for correlations of POP staging in different compartments and LUTS (stress urinary incontinence, overactive bladder and voiding symptoms) as well as their associated factors.
Only OAB had a moderate correlation with different compartments of POP (anterior vaginal wall: -0.3116; cervix: -0.2954 and posterior vaginal wall: -0.3779; all p < 0.05). Stage 1 AVWP significantly increased (39.6%) the occurrence of OAB compared to no prolapse. Posterior compartment (stage 1-3) prolapse reduced the occurrence of OAB.
Only stage 1 AVWP is associated with an increase in OAB, and posterior compartment prolapse may reduce the occurrence of OAB.
