[Methicillin-resistant Staphylococcus aureus (MRSA) infection in urological field--clinical backgrounds and clinical course].

The Staphylococcus aureus in this study were isolated from 33 outpatients and 38 inpatients of the Department of Urology from August 1989 to April 1991. Twenty one patients (29.5%), three outpatients, had the MRSA type. Significant correlations were found between the incidence of MRSA infection and such factors as diabetes mellitus and the isolation of MRSA within 7 days of the administration of antibiotic agents. Out of 14 MRSA which were investigated for coagulase type, 9 were type VII. This indicates an outbreak of MRSA in the urological ward. Seven cases of MRSA and 5 cases of MRSA had high grade fever (over 38 degrees C), but all patients experienced much relief by using susceptible antibiotic agents. Our study shows that the isolation frequency of MRSA has increased in urological field. Therefore, we think it is important to treat patients with MRSA infection adequately, especially when there are compromised hosts in the same room.
