Is there a need for bacterial endocarditis prophylaxis in patients undergoing urological procedures?

Heart valve repair or replacement is a serious problem.The focused update on infective endocarditis of American College of Cardiology/American Heart Association 2008 (ACC/AHA guidelines) and Guidelines on the prevention, diagnosis, and treatment of infective endocarditis (new version 2009) of the European Society of Cardiology (ESC guidelines) describe prophylaxis against infective endocarditis as not recommended for urinary tract procedures in the absence of active infection. A statistical association has been recently shown between urological procedures and the development of infective endocarditis. New evidences concerning infective endocarditis due to Actinobaculum schaalii, Neisseria gonorrhoeae, Streptococcus agalactiae, Enterococcus faecalis, Pseudomonas aeruginosa, Aerococci and Staphylococcus aureus, and new findings indicate there is a need for bacterial endocarditis prophylaxis in patients undergoing urological procedures especially in elderly patients and in cancer and immunocompromised patients, to avoid serious consequences.
