Abstract: 

Published studies on community-acquired urinary tract infections (UTI) often do not link microbiological findings with clinical risk factors and patient data.

We retrospectively correlated clinical findings of all patients with UTI of a urological outpatient clinic with the respective microbiological analysis of their urine samples over 2 periods of time: (A: 2005-2006 and B: 2011-2012). Patients were stratified to the following risk groups: uncomplicated cystitis, diabetes mellitus type 2, nursing home resident, prostatitis/epidydimitis, permanent catheter.

The incidence of Escherichia coli (p < 0.001) and proteus (p < 0.001) significantly decreased from period A to B, while enterococci (p = 0.003) and staphylococci (p < 0.001) significantly increased. Antibiotic sensitivity to fosfomycin (p < 0.001), doxycycline (p < 0.001), nitrofurantoin (p < 0.001), and nitroxoline increased (p < 0. 001) and sensitivity to amoxicillin (p < 0.001) and gentamicin decreased (p < 0.001). Patients with a permanent catheter had significantly poorer sensitivity rates (50% and less) for almost all antibiotics tested compared to the overall group. The risk of a UTI with 3MRGN or MRSA bacteria was significantly higher for catheter carriers and nursing home residents.

Empiric antibiotic first-line therapy with nitrofurantoin and fosfomycin for uncomplicated community acquired UTIs are well indicated in conformity with guidelines. The accumulation of multiresistant pathogens in patients with a permanent bladder catheter requires restrictive use of any permanent catheter drainage.
