Ecology and fluoroquinolon resistance profiles in febrile urinary tract infections (FUTI) after prostate needle biopsy: A retrospective study in 466 biopsies
Résumé
Objective. - The biopsies of prostate are the reference examination to assert the diagnosis of prostate cancer. Even if the urinary infectious complications are rare thanks to the systematic oral antibiotic prophylaxis, they may still be serious. The SPILF (Society of Infectious Pathology and French language) published in 2014, an important increase of the resistances in fluoroquinolones for Escherichia coil (3 to 25%), whereas this is the most bacterium frequently found in the urinary infections (70-80%). The objectives of this study were to estimate the indicence of the febrile urinary tract infections after prostate needle biopsy and to define the ecology and the profile of E. coil's resistance. Methods. - A total of 466 transrectal ultrasound-guided needle prostate biopsy were included in the study from 2012 to 2015. All the patients were taken care according to the recommendations of the AFU (Ouzzane et al., 2011). We estimated, for all the inclusive patients, if they had presented a clinic sign of urinary infection like fever or burning which suggestive of an urinary infection, and having a urines and blood culture, in the next 30 days the realization of the medical exam. Results. - Among 466 realized biopsies, seven patients developed a febril urinary tract infection (1.5%) [prostatitis (n=6), orchitis (n=1)]. Five infections to E. coil were identified; two were resistant for fluoroquinolones (40%). No germ was able to be identified for two patients. Conclusion. - The infectious complications post-biopsy of prostate are rare (1.5%). E. coil is the germ most frequently identified with 40% of resistance with fluoroquinolones.
