| Abstract |
Urinary tract infections consist of 40% of hospital infections and appearance of resistant bacteriae are increasing more and more nowadays due to antimicrobial agents abuse. Authors observed underlying diseases of suspicious urinary tract infections and hope that this study may help the choice of antibiotics and proper treatment of urinary tract infection. The 317 cases of inpatients and the 95 cases of outpatients with urinary tract infections were evaluated for causative organisms and antibiotic susceptibility during 1 year from July 1989 to June 1990.
The following results were obtained
1. There were 134 male patients and 278 female patients among total 412 patients were observed. The ratio of male patients to female patients was 1:2.1.
2. The underlying conditions of outpatients were found in 54 cases. The most common disease were urolithiasis(18.5%) and BPH(16.7%), diabetes mellitus(14.7%), cervix cancer(7.4%), indwelling catheter(7.4%), vesicoureteral reflux(5.6%), prostatic cancer(5.6%) ureteral stricture(3.6%), bladder diverticulum(3.6%) were followed.
3. The most common pathogens were E. coli(40.9%) and Staphylococcus(9.7%), Enterococcus(9.6%), Pseudomonas(8.4), Klebsiella(6.2%) according to the order.
Serratia and Enterococcal infections of inpatients were significantly more common than that of outpatients.
4. Mixed urinary tract infections were observed in 18.6% of inpatients and in 10.5% of outpatients. The most common causative organisms was E.coli(inpatient;14.8%, outpatient;21.7%).
5. E.Coli from outpatients and inpatients was sentive to cefotaxime and ofloxacin.
Pseudomonas was resistant to most of antibiotics except ofloxacin.
6. The susceptibility of Staphylococcus was low to penicillin and high to ofloxacin.
The susceptibility to ampicillin of Enterococcus was 80.0% in outpatients and 84.6% in inpatients. |
