菌尿症是指尿培养菌落计数≥105 CFU/mL。在患有无症状性菌尿症(ABU)的糖尿病患者、孕妇、尿路梗阻患者中一定比例的患者会发生肾盂肾炎,ABU与发生肾盂肾炎有相关性。一项治疗妊娠期ABU能降低症状性尿路感染风险的研究为该观点提供了依据。另有研究表明,在尸检中发现所有肾盂肾炎病例中只有1/5在生前被确诊,原因在于临床上多数患者症状不典型或感染不明显所以认为无论是
Bacteriuria means urine culture colonies count ≥ 105 CFU / mL. In diabetic patients with asymptomatic bacteriuria (ABU), pregnant women, a certain proportion of patients with urinary tract obstruction pyelonephritis occurs, and ABU is associated with pyelonephritis.

Another study showed that in autopsy found that only 1/5 of all cases of pyelonephritis were diagnosed during their lifetime, because most patients in clinical symptoms or atypical symptoms is not obvious so that no matter
