Asymptomatic bacteriuria

Asymptomatic bacteriuria, also known as occult bacteriuria, is a type of occult urinary tract infection, which means that the patient has true bacterial urine (the clean medium-term urinary bacterial quantitative culture is greater than 105 / ml twice in a row, and the bacteria are the same twice. And the false positive result was excluded) without any symptoms of urinary tract infection, but in some cases, mild symptoms can be found after careful inquiry. Its bacteria come from the kidneys or from the bladder. The incidence of asymptomatic bacterial urine is higher than that of symptomatic patients. The incidence is 4% in women aged 16 to 65 and 0.5% in men. Although 1/4 of bacterial urine disappears in female patients, but New bacterial urine also continues to occur, so the incidence of 4% is fairly constant.
