The effect of pelvic organ prolapse severity on improvement in overactive bladder symptoms after pelvic reconstructive surgery.

INTRODUCTION AND HYPOTHESIS: This study evaluates the effect of baseline pelvic organ prolapse (POP) severity on improvement in overactive bladder (OAB) symptoms after pelvic reconstructive surgery.
METHODS: We performed a retrospective cohort study of women with POP and OAB who underwent surgical correction of symptomatic apical and/or anterior POP. OAB was defined as an affirmative response to item #15 (urinary frequency) and/or item #16 (urge incontinence) of the Pelvic Floor Distress Inventory (PFDI). POP severity was dichotomized as Pelvic Organ Prolapse Quantification (POP-Q) stage 1-2 versus stage 3-4. Our primary outcome was complete resolution or improvement of urinary frequency or urge incontinence on the PFDI 12 months postoperatively.
RESULTS: At 12 months postoperative, 41 (89%) women with stage 1-2 POP versus 47 (85 %) with stage 3-4 POP reported improvement in urinary frequency (p = 0.58). Thirty five (90 %) with stage 1-2 and 34 (85 %) with stage 3-4 POP reported improvement in urge incontinence (p = 0.74). On multiple logistic regression, women with stage 3-4 POP had a decreased odds of improvement in frequency or urge incontinence compared with women with stage 1-2 POP (adjusted odds ration [AOR] = 0.06 [95 % CI 0.01-0.67]), after adjusting for confounders.
CONCLUSIONS: Women with coexisting POP and OAB who undergo surgical correction of POP experience improvement in OAB symptoms after surgery, although women with more severe POP may be at a higher risk of persistent frequency or urge incontinence.
