[Upper urinary tract infections in adults: about 261 episodes]

ABSTRACT

Upper urinary tract infections are frequent. Escherichia coli is the main pathogen identified from community acquired infections. We aim to study epidemiologic, clinical and bacterial features of this infection. We identified 261 episodes that occurred in241 patients. They were 213 females and 48 males aged of 48, 75 years. Enterobacteriaceae were the main pathogens isolated in 93,5% E. coli in 73,3% and Klebsiella pneumoniae in 15,3%. E.coli sensitivity was of 30% for amoxicillin, 98% for cefotaxim, 96% for gentamicin, 90% for ciprofloxaine and 56% for co-trimoxazole. Anterior antibiotic use was associated with low E. coli sensitivity mainly with fluoroquinolones [96 vs 77%] and co-trimoxazole [62 vs 43%]. This enhances the role of antibiotic pressure on the resistance emergence. The reasonable use of antibiotics is necessary to limit resistance extent
