This study aimed to assess the prevalence of urinary incontinence (UI) and lower urinary tract symptoms (LUTS) in five selected low and middle-income countries to provide appropriate evidence for other related studies.BACKGROUND AND OBJECTIVEThis study aimed to assess the prevalence of urinary incontinence (UI) and lower urinary tract symptoms (LUTS) in five selected low and middle-income countries to provide appropriate evidence for other related studies.In this multinational population-based cross-sectional survey between August 2019 and April 2021, validated questionnaires were used to assess LUTS in adults over 18 years from Iran, Egypt, Bangladesh, Brazil, and Cameroon.MATERIALS AND METHODSIn this multinational population-based cross-sectional survey between August 2019 and April 2021, validated questionnaires were used to assess LUTS in adults over 18 years from Iran, Egypt, Bangladesh, Brazil, and Cameroon.A total of 1477 participants from five countries completed the questionnaires. The mean age of participants was 43.5 ± 15.7 years. 37.1% reported at least one episode of UI per week. UUI prevalence in different countries analysis showed that the commonest prevalence was reported in Cameron (40.0%; n = 30), while the lowest was 15.0% (n = 31) in Brazil. Stress UI was common in Iran (38.7%; n = 338), and Bangladesh had the lowest rate (7.8%; n = 16). Urinary urgency was the common LUTS among participants (59.9%, n = 818 out of 1477 participants). Nocturia was the other prevalent symptom among cases (50.6%; 748 out of 1477 cases), and this symptom had a higher rate in elderly populations. Men reported voiding and postmicturition symptoms more frequently than women. Storage symptoms except for nocturia, including frequency, urgency, and UI were common in women while voiding symptoms, including straining, and intermittency were reported more frequently in men than women.RESULTSA total of 1477 participants from five countries completed the questionnaires.
