在老年人中无症状性菌尿是常见的。人群调查发现65岁以上老年人男性6～20％、女性17～33％存在无症状性菌尿,而住院病例所占比例将会更高。过去,因无足够证据证明无症状性菌尿影响肾功能或死亡率的有害性,故一般不用抗生素治疗。最近研究表明,有菌尿的老年男女均比无菌尿者死亡率高,老年菌尿患者肾小管功能明显受损,因
Asymptomatic bacteriuria is common in the elderly. Population survey found that 6 to 20% of men over the age of 65 and 17 to 33% of women have asymptomatic bacteriuria, while the proportion of inpatient will be higher. In the past, there was generally no antibiotic treatment because there was not enough evidence to prove the harmfulness of asymptomatic bacteriuria affecting renal function or mortality. Recent studies have shown that older men and women with bacteriuria have higher mortality rates than those with sterile urine, and renal function of patients with geriatric bacilli is significantly impaired due to
