Objective: To understand Primary Health Care nurses’ role in treating Lower Urinary Tract Dysfunction. Method: Cross-sectional multi-methodological research, composed of quantitative and qualitative steps, independently and sequentially. Data collected remotely, through a questionnaire and focus group, analyzed using descriptive statistics and thematic analysis by Braun and Clarke, respectively. The project was approved under Opinion 22691119.0.0000.0030. Results: A total of 145 nurses participated in the study in the quantitative step and 20 in the qualitative step, working in Primary Health Care in Brazil. Of the 93.1% nurses who reported having already cared for people with Urinary Tract Dysfunction, only 54.4% provided guidance, mainly for training the pelvic floor muscles. Conclusion: Even though they have legal support and access to demand, nurses do not have the knowledge to offer conservative treatment for Lower Urinary Tract Dysfunction. Despite this, they were motivated to do so as long as they received specific training.
