Abstract
To investigate the rate of occurrence, clinical presentation, predisposing factors and frequency of secondary bacteremia, 132 patients with significant S. aureus bacteriuria were reviewed retrospectively. S. aureus accounted for 3.3% of all positive urine cultures. Most patients were elderly men. The most important predisposing factors in the urinary tract were indwelling catheters (63%), obstruction (56%) and instrumentation or surgery (43%). Bacteremia developed secondary to bacteriuria in all 11 patients (8.3%). For that reason S. aureus bacteriuria should be regarded as a hazardous condition, especially in patients with predisposing factors in the urinary tract.
