Epidemiological and clinical aspects of 270 episodes of urinary tract infection caused by Staphylococcus saprophyticus were studied. The cases were randomly selected and matched consecutively with 276 others of urinary tract infection according to sex, age and temporal occurrence. Such infections were found typically among young women in the outpatient health service. They were common among professionals handling meat products and were especially associated with prior outdoor swimming. Common symptoms of inflammation of the lower urinary tract, haematuria and pyuria were seen more often among patients with S. saprophyticus infections. Some cases of asymptomatic S. saprophyticus infection, however, were seen. We found S. saprophyticus as the cause of 13% upper urinary tract infections, an incidence which is higher than has been reported for other bacteria. Staphylococcus saprophyticus was less correlated to nephrolithiasis and was not a common cause of catheter-induced infections.
对270例腐生葡萄球菌引起的尿路感染病例的流行病学和临床特征进行了研究。这些病例是随机选取的，并根据性别、年龄和发病时间与另外276例尿路感染病例连续匹配。此类感染多见于门诊健康服务中的年轻女性。在处理肉类产品的专业人员中很常见，尤其与之前的户外游泳有关。腐生葡萄球菌感染患者更常出现下尿路感染、血尿和脓尿等常见炎症症状。然而，也发现了一些无症状的腐生葡萄球菌感染病例。我们发现腐生葡萄球菌是13%上尿路感染的病因，这一发病率高于其他细菌的报道。腐生葡萄球菌与肾结石的相关性较小，不是导管相关感染的常见原因。
