Problem: urinary tract infections are one of the main conditions that occur in the pregnancy period, causing important maternal-fetal complications that can lead to death. Aims: to implement an educational booklet on the prevention of urinary tract infections in a group of pregnant women and analyze the nursing problems related to the occurrence of this disease. Method: a descriptive, qualitative study with fifteen pregnant women at a Family Health Unit in Petrópolis, RJ, Brazil in April, 2015. Data was collected through interviews - individual and group - and was analyzed using the data triangulation technique. Results: the application of the booklet revealed nursing problems related to hygiene, food, water intake, intestinal and urinary elimination and coitus. Conclusion: the use of printed technology is an important tool for discussion and learning in the health education process, and it can be used to qualify the nurses' care practice.
