诊断尿路感染(下简称尿感)的诊断不能仅依靠症状而确定,因有时症状可不典型,而且,许多病例可全无症状。故目前认为,尿感的诊断标准应是:凡是尿路内有真性细菌尿者,即为尿路感染。真性细菌尿的定又是:①膀胱穿刺尿定性培养有细菌生长,或②导尿作细菌定量培养,其结果≥10~5/ml,或③(?)洁中段尿细菌定量培养≥10~5/m1,但如没有尿感症状,则要2次中段尿细菌培养的结果均≥10~5/ml,且为同一病菌。中段尿细菌定量培养的阳性标准,国内外均曾有争
The diagnosis of urinary tract infection (hereinafter referred to as urinary flu) can not be diagnosed solely on the basis of symptoms, because sometimes the symptoms are not typical, and many cases can be asymptomatic. Therefore, the current view that the diagnostic criteria of urinary tract should be: urinary bacteria who have true urine, that is urinary tract infection. True bacteriuria urine set is: ① bladder puncture urine qualitative culture of bacterial growth, or ② catheterization for bacterial quantitative culture, the results ≥ 10 ~ 5 / ml, or ③ (?) Clean urine bacterial quantitative culture ≥ 10 ~ 5 / m1, but if there is no symptoms of urinary tract infection, then the results of secondary urinary bacterial cultures should be ≥10 ~ 5 / ml, and for the same bacteria. Urinary bacteria in the middle quantitative culture of positive standards, both at home and abroad have had controversy
