Nosocomial Urinary Infections at the Urogoly Unit of the National University Hospital (Yalgado Ouedraogo), Ouagadougou: Feb.-Sept. 2012

Abstract

Objective : The aim of this study was to identify the risk factors and the microorganisms susceptibilities of nosocomial urinary infections at the urology unit of the national university hospital of Ouagadougou in Burkina Faso. Method : From February to September 2012, two bacteriological analyzes have been performed for any of the 75 inpatients in the urology unit of the national university hospital of Ouagadougou in Burkina Faso. Results : During the study period, 43 cases of nosocomial urinary infection were identified (57.3%) and we found no statistically significant associated risk factors with age groups, sex, arterial blood pressure, kidney illness and urinary obstructive pathologies. The most frequently isolated bacteria were Escherichia coli (30.9%), Klebsiella spp (26.9%) and Staphylococcus spp (15.4%). The yeasts strains were very sensitive to antifungal but the bacteria susceptibility rate to antibiotics was very variable. Thus, the cocci were rather sensitive to association clavulanic acid + amoxicilline and ceftriaxone and enough sensitive to gentamicine ; the bacilli were enough sensitive to gentamicin and very sensitive to imipenem. Conclusion : From the antibiogram results, we recommend gentamicin in combination with penicillin or metronidazole as the first antibiotics to be used in the treatment of nosocomial urinary tract infections.
