Treatment of MDR urinary tract infections with oral fosfomycin: a retrospective analysis.

Objectives: Limited options for treating MDR organisms have led clinicians to turn to older antimicrobial agents that may display activity against such infections. One such agent is fosfomycin, an oral drug with activity against a variety of Gram-positive and -negative bacteria, but only approved for use in the USA for urinary tract infection (UTI) due to Escherichia coli and Enterococcus faecalis. The purpose of this study was to assess the efficacy of fosfomycin treatment of MDR UTI and identify predictors of outcome.
