Urogynecological conditions associated with overactive bladder symptoms in women
Introduction: Overactive bladder symptoms (OAB) affect 9–43% of women and are associated with underlying disorders, including pelvic organ prolapse (POP) and stress urinary incontinence (SUI). The aim of this study is to identify urogynecological conditions associated with OAB symptoms.
Methods: This prospective, institutional review board-approved study included women referred to a tertiary centre with lower urinary tract symptoms (LUTS). All women completed the selfadministered OAB questionnaire (OABSS). Those with an OABSS ≥8, the cutoff, were considered to have OAB symptoms. Patients underwent a history and physical examination (including Baden- Walker prolapse grading and stress test), 24-hour voiding diary, pad test (for urinary incontinence), urinalysis, and uroflow with post-void residual volume. Patients were classified clinically into the following: idiopathic OAB, SUI, POP, bladder outlet obstruction (BOO) neurogenic bladder (NGB), recurrent urinary tract infection (UTI), and miscellaneous.
Results: In total, 148 women met the inclusion criteria with a mean age of 67 years. Only 27% had no comorbid conditions and were considered idiopathic OAB. Associated urogynecological conditions included SUI in 37%, POP in 26%, miscellaneous conditions in 18%, recurrent UTI in 11%, NGB in 9%, and BOO in 8%. Some patients met criteria for more than one category, thus the total is greater than 100%.
Conclusions: In a tertiary care setting, a significant proportion of women with OAB symptoms have underlying conditions that may cause or contribute to their symptoms. Appropriate evaluation is desirable to enhance our understanding of the relationship of these conditions to the diagnosis, treatment, outcomes, and pathophysiology of OAB.
