[Ertapenem administered intravenously or subcutaneously for urinary tract infections caused by ESBL producing enterobacteriacea].

Introduction: Ertapenem could be used to treat urinary tract infections (UTI) caused by ESBL producing enterobacteriacae (ESBL-E) and administered subcutaneously.

Method: The authors made a retrospective study on adult patients treated with ertapenem administered intravenously or subcutaneously for UTI caused by ESBL-E, between May 2009 and August 2011 at the Chambery hospital, France.

Results: Twenty-five patients were treated (13 cases of prostatitis, ten of pyelonephritis, two of cystitis) mostly caused by Escherichia coli (24 cases).
