Abstract

Summary
Women with obesity are at risk of pelvic floor dysfunction with a 3-fold increased incidence of urge urinary incontinence (UUI) and double the risk of stress urinary incontinence (SUI). The National Institute for Health and Care Excellence (NICE) and European Association of Urology (EAU) recommend that women with a body mass index ≥30 kg/m2 should consider weight loss prior to consideration for incontinence surgery. This systematic review and meta-analysis will assess this recommendation to aid in the counselling of women with obesity-related urinary incontinence (UI). Medical Literature Analysis and Retrieval System online (MEDLINE), EMBASE, Cochrane, ClinicalTrials.gov, and SCOPUS were systematically and critically appraised for all peer reviewed manuscripts that suitably fulfilled the inclusion criteria established a priori and presented original, empirical data relevant to weight loss intervention in the management of urinary incontinence. Thirty-three studies and their outcomes were meta-analysed. Weight loss interventions were associated in a decreased prevalence in UI (OR 0.222, 95% CI [0.147, 0.336]), SUI (OR 0.354, 95% CI [0.256, 0.489]), UUI (OR 0.437, 95% CI [0.295, 0.649]) and improved quality of life (PFDI-20, SMD -0.774 (95% CI [−1.236, −0.312]). This systematic review and meta-analysis provide evidence that weight loss interventions are effective in reducing the prevalence of obesity-related UI symptoms in women. Bariatric surgery in particular shows greater sustained weight loss and improvements in UI prevalence. Further large scale, randomized control trials assessing the effect of bariatric surgery on women with obesity-related UI are needed to confirm this study's findings.
