[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1994). II. Background of patients].
Clinical background was investigated on 628 bacterial strains isolated from patients with urinary tract infections (UTIs) in 10 hospitals during period from June, 1994 to May, 1995. 1. Distributions of sex, age and urinary tract infections Among over sixties 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. As for over 40 females, the increase of complicated UTI was admitted. 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 and CNS. In complicated UTIs without indwelling catheter, E. coli, Pseudomonas aeruginosa and E. faecalis were isolated the most frequent. In complicated UTIs with indwelling catheter, P. aeruginosa was most frequently isolated, and next E. faecalis and Staphylococcus aureus. 3. Administration of antimicrobial agents and pathogens isolated from UTIs In uncomplicated UTIs, pathogens, after administration of antibiotics, isolated from patients have obviously decreased from 216 to 32 isolates. And also, pathogens of complicated UTIs without indwelling catheter, have decreased from 127 to 50 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 factor and operation E. faecalis was mainly detected, and next E. coli, S. aureus and P. aeruginosa. Without factor and operation, E. coli was mainly detected. In complicated UTIs with indwelling catheter and with factor and operation, P. aeruginosa, E. faecalis and S. aureus were mainly detected at 23.5%, 15.0%, 15.0%, respectively. Without factor and operation, Proteus spp. 22%, and next E. faecalis and P. aeruginosa 10% and 12%, were detected, respectively. The distribution of pathogens, in the case of Proteus spp. and P. aeruginosa has been obviously varied by the influence of factor and operation.
