ObjectiveLower urinary tract symptoms (LUTS) can frequently be seen in pregnant women. Pregnancy and delivery have been considered as risk factors in the occurrence of pelvic floor dysfunction and determinants of LUTS. The main associated risk factor is parity. In the present study, we aim to determine the frequency of LUTS and urinary incontinence (UI) during pregnancy and the associated risk factors.MethodsThis prospective study was carried out in a total of 250 women during their 28‐ and 40‐gestational week checks. The Urinary Distress Inventory‐6, the Incontinence Impact Questionnaire‐7, and International Consultation on Incontinence Questionnaire‐Short Form were used to determine LUTS and its effect on quality of life.ResultsThe mean age and gestational age of the participants were 29.41 ± 5.70 year (range 18–44) and 35.45 ± 2.98 weeks (range 28–40), respectively. The prevalence of LUTS was 81.6%. The prevalence of UI during pregnancy was 37.2%. Stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence were diagnosed as 15.6, 4.8 and 16.8%, respectively. We found that advanced age, smoking and multiparity were risk factors associated with incontinence. Incontinence reduced pregnant women's quality of life.ConclusionsLower urinary tract symptoms are commonly seen among pregnant women and these symptoms negatively affect the quality of life of pregnant women. Advanced age, smoking and multiparity were risk factors associated with urinary incontinence and LUTS. Obstetricians should be on the lookout for individual urological problems in pregnancy. Resolving any urological issues and cessation of smoking for the affected individuals will help alleviate the problem.
