INTRODUCTION: Urinary incontinence is currently defined by the International Incontinence Society as a complaint of any involuntary leakage of urine. During pregnancy, there are many changes in the function of the pelvic floor, which in turn can lead to urinary incontinence. OBJECTIVE: The aim of this study was to examine the incidence of urinary incontinence before and during pregnancy and how well pregnant women are informed about the occurrence of urinary incontinence. MATERIAL AND METHODS: Pregnant women from the territory of the Republic of Croatia were included in the research, and a total of 249 pregnant women participated in the research in the period from 1 March to 1 April 2022 via an online questionnaire. RESULTS: Most difficulty urinating (frequency of urination, nocturia, hematuria, dysuria, difficulty in starting or during urination) as well as the presence of urinary incontinence in the subjects were significantly more common during pregnancy compared to the period before pregnancy. The incidence of involuntary leakage of urine increases during pregnancy by a total of 40.1% compared to the time before pregnancy. The table shows an increase in the impact of involuntary leakage of urine on daily life by 41.4%. In other words, in 103 figures, involuntary leakage of urine during pregnancy affected them to a greater extent, compared to the time before pregnancy. Awareness by gynecologists is 41% (n = 103) and by midwives 18% (n = 45). Out of a total of 104 pregnant women who received help, the results indicate that the help provided to most pregnant women was not effective, more precisely to 42 (40.4%) pregnant women. CONCLUSION: This study confirms the high incidence of urinary incontinence in women during pregnancy in the Republic of Croatia, which consequently affects their daily lives. The results indicate that the assistance provided related to involuntary leakage of urine was not effective for most pregnant women.
