Asymptomatic bacteriuria?

summary

Asymptomatic bacterial urine, also known as occult bacterial urine, is a kind of occult urinary tract infection, which refers to patients with genuine bacterial urine without any clinical symptoms of urinary tract infection. It is often found in healthy people for physical examination or routine urine bacteriological examination due to other kidney diseases. Let's talk about the symptoms of this situation.

Asymptomatic bacteriuria?

Asymptomatic bacteriuria, also known as occult bacteriuria, is a kind of occult urinary tract infection, which means that the patient has genuine bacteriuria (the bacterial quantitative culture of clean midstream urine is more than 105 / ml for two consecutive times, and the bacteria species are the same for two times, and the false-positive results are definitely ruled out) without any symptoms of urinary tract infection, but in some cases, slight symptoms can be found after careful inquiry. The bacteria come from the kidney or bladder. The incidence rate incidence rate of asymptomatic bacteriuria is higher than that of those with symptoms. The incidence rate of 16~ is 65 in women, 4% in men, 0.5% in men, while 1/4 bacteria urine can disappear in female patients, but new bacterial urine is also constantly occurring, so the incidence of 4% is quite constant.

Asymptomatic bacteriuria is common in pregnant women, puerpera and girls. The incidence rate of bacterial urine was 4.5% in the pregnant women, and 82% of them were asymptomatic. In these asymptomatic bacterial urine patients, about 50% is pyelonephritis. Asymptomatic bacteriuria has no manifestation of urinary tract infection, only occasionally has mild fever and fatigue, but has positive urine bacterial culture for many times. In the past, it was considered as a benign process without treatment. Now a lot of studies have confirmed that long-term asymptomatic bacteriuria can also damage renal function, so the treatment should be the same as symptomatic urination.

Asymptomatic bacterial urine can be evolved from symptomatic urination, that is, symptomatic urination will disappear naturally or after treatment, but only bacterial urine will remain, and can last for many years. Some patients with bacterial urine may have no previous history of acute urination. In addition, urination after the use of urinary instruments and on the basis of chronic kidney disease often has no obvious symptoms.

matters needing attention

Due to the increase of antimicrobial resistance, asymptomatic bacteriuria is more likely not to be treated at present, unless the evidence that patients can benefit from it is obtained. Pregnant women should be screened for asymptomatic bacteriuria in the first 3 months of pregnancy. If it is positive, it is necessary to treat it. However, patients with diabetes, the elderly, indwelling catheter and spinal cord injury do not seem to benefit from the treatment of asymptomatic bacteriuria.
