Objective: To unveil the senses and meanings of conservative treatment in people with chronic kidney disease (CKD). Materials and Methods: A descriptive and exploratory study with a qualitative approach. It was developed in 2017, with a sample of individuals with CKD undergoing conservative treatment. A semi-structured interview was used and the data were analyzed using simple descriptive statistics and content analysis.
