Clinical background was investigated on 632 bacterial strains isolated from patients with urinary tract infections (UTIs) in 11 hospitals during the period from June, 1991 to May, 1992. 1. Distribution of sex, age and infections Among over forties males, the majority was taken by complicated urinary tract infections. Among females, the uncomplicated urinary tract infections was most frequent without a relation of age. 2. Distribution of sex, age and pathogens isolated from UTIs In uncomplicated UTIs, Escherichia coli was most frequently isolated without a relation of age, and next Enterococcus faecalis in over fifties. In complicated UTIs without indwelling catheter, E. coli and E. faecalis were isolated with a frequency of 17.4-26.6%, respectively. In complicated UTIs with indwelling catheter, E. faecalis were most frequently isolated, and next Pseudomonas aeruginosa. 3. Administration of antibiotics and pathogens isolated from UTIs In uncomplicated UTIs, pathogens, after administration of antibiotics, isolated from patients have obviously decreased from 319 to 34 isolates. And also, pathogens of complicated UTIs without indwelling catheter, have decreased from 122 to 49 isolates. However, in complicated UTIs with indwelling catheter, pathogens after or before administration of antibiotics, were not revealed an obvious change. 4. Pathogens and UTIs with or without factor and operation In uncomplicated UTIs with or without factor and operation, E. coli was mainly detected. In complicated UTIs without indwelling catheter and with or without factor and operation, E. faecalis and E. coli were mainly detected. In complicated UTIs with indwelling catheter and with factor and operation, E. faecalis and P. aeruginosa were detected, 24.3% and 22.9%, respectively. Without factor and operation, E. faecalis was detected 18.4%, and next Klebsiella spp. 15.8%. And the distribution of pathogens after administration of antibiotics was similar.
