Ⅰ、妊娠和肾疾病1.无症状性菌尿Kass将尿细菌数分为10~4/ML以下和10~5/ML以上两组,显性尿路感染者95%为后组,因此把尿中细菌数为10~5/ML的称为细菌尿。而将细菌数在10~5/ML以上却全无症状的称为无症状性菌尿,此为妊娠时肾盂肾炎的很主要的原因。孕妇的年龄、经产次数和无症状性菌尿的发生率有关,平均为4～7%。Norden认为21岁以下的初产妇为2%,而35岁以上的经产妇为8～10%。总之,具有无症状性菌尿的孕妇,35～40%的人发展为显性的急性肾盂肾炎。因此,特别是对合并蛋白尿和糖尿的孕妇,尿中细菌的检查是很重要的。进而根据Kass,Kincaid—smith报道无症状性菌尿孕妇的未
Ⅰ, pregnancy and kidney disease 1. Asymptomatic bacteriuria Kass will be divided into 10 to 4 / ML urinary bacteria and 10 ~ 5 / ML above two groups, 95% of dominant urinary tract infection for the latter group, so the The number of bacteria in urine is 10 ~ 5 / ML called bacterial urine. While the number of bacteria in the 10 ~ 5 / ML above all asymptomatic symptoms of asymptomatic bacteriuria, this is the main cause of pyelonephritis during pregnancy. The age of pregnant women, the frequency of production and the incidence of asymptomatic bacteriuria, with an average of 4 to 7%. Norden believes 2% of primipara 21 years of age, and 8 to 10% of women over 35 years of age. In short, pregnant women with asymptomatic bacteriuria, 35 to 40% of people develop dominant acute pyelonephritis. Therefore, especially in pregnant women with proteinuria and diabetes mellitus, the examination of bacteria in the urine is very important. According to Kass, Kincaid-Smith reported asymptomatic bacteriuria in pregnant women
