Prevalence of Pelvic Floor Disorders in the Fibromyalgia Population: A Systematic Review.

This study aimed to review the literature to establish the prevalence of pelvic floor disorders in the fibromyalgia population. A systematic literature search through computerized databases including PubMed and EMBASE was completed using medical subject heading (MeSH) terms from January 1, 1990 to November 1, 2017. Articles were included if the focus was prevalence of pelvic floor disorders in the population of persons with fibromyalgia. To provide consistency of diagnosis, use of the American College of Rheumatology 1990 or 2010 criteria was required. Evidence was graded according to Canadian Task Force on Preventive Health Care and Newcastle-Ottawa quality assessment scales. A total of 11 studies were deemed eligible for inclusion from 1024 articles initially identified. Only one study used the most recent 2010 American College of Rheumatology diagnostic criteria. There was significant heterogeneity in the reporting of fibromyalgia populations. Outcomes reported were variable and not consistent across studies; thus, data could not be pooled. There appears to be a high prevalence of gastrointestinal, genitourinary, and gynaecological dysfunction. In case-control studies, these dysfunctions appeared to be more prevalent in the fibromyalgia group than in the control populations. However, this difference could not be quantified more specifically. In conclusion, the small number of eligible studies and the variety of pelvic floor outcomes reported limited formation of conclusive prevalence of pelvic floor disorders in the fibromyalgia population. From the small number of studied patients, there may be a higher prevalence of gastrointestinal, genitourinary, and gynaecological concerns in women with fibromyalgia. Crown
