ABSTRACT Objectives: to assess the prevalence and associated risk factors for urinary tract infection in patients with chronic kidney disease under conservative treatment and identify the microorganisms isolated in the urine of these patients and the staging of chronic kidney disease. Methods: a cross-sectional, analytical study carried out at the Conservative Treatment Outpatient Clinic of a university hospital in the city of São Paulo. Results: the prevalence of urinary tract infection is 22%. The risk factors Diabetes Mellitus, hypertension, heart disease, neoplasms and thyroid and autoimmune diseases stand out in the infected group (p < 0.001). Most of the microorganisms found in urine cultures (87.9%) were Gram-negative, being Escherichia coli (50.70%), followed by Klebsiella pneumoniae (23.1%) and Enterococcus spp. (9.7%). Conclusions: the findings of this investigation reveal the intrinsic association between risk factors and microorganisms for the development of urinary tract infection.
