Introduction: Urinary tract infection associated with indwelling urinary catheter accounts for about 40.0% of health care-related infection. Objective: To identify, based on literature review, the factors associated with biofilm formation in an indwelling urinary catheter. Method: An integrative review conducted in the databases: Medline, Lilacs, IBECS, PubMed and Portal Capes, using the descriptors “urinary tract infections”, “urinary catheters” and “biofilm”, with articles published in full between 2009 and 2016 in English, Spanish or Portuguese. Results: Eight articles were selected, four systematic reviews and four observational studies. A biofilm on an indwelling urinary catheter is formed by the fixation that is initiated by the deposition of urine on the surface of the catheter. The factors associated with biofilm formation on an indwelling urinary catheter were type of microorganisms (87.5%) (presence of flagella, motility and production of urease), structural conformation (37.5%) in latex (irregular hydrophobic and hydrophilic surfaces) that allow the adhesion and colonization by several microorganisms, and the female sex (12.5%). Conclusion: This review identified the factors that were associated with biofilm formation in an indwelling urinary catheter and contributes to the proposal of effective prevention measures focused on patient safety.
