[Role of biofilm in urology].

The particular organization of bacteria as a biofilm on surfaces plays an essential role in urology because of the increasing use of prosthetic materials. Although the biocompatibility of the various materials used is now more effectively controlled, colonization of surfaces by microorganisms is frequent and the formation of a biofilm is responsible for difficulties encountered during treatment of prosthetic infections. The problems concerning the detection and eradication of biofilm led the authors to propose a brief review of the growing understanding of biofilm in urology over the last five years.
