Urine sediment quantitative analysis of bacteria 23/high-power field of view, suggesting an increase in bacteria in the urine, may be related to contaminated urine, but also may be related to cystitis, pyelonephritis, gonorrhea and other diseases. There is no bacteria in the urine of normal people, if the quantitative analysis of urine sediment bacteria 23 / high power visual field suggests that there are bacteria in the urine, but because the urine is usually collected by the person himself specimen and then given to the medical workers, there may be improper operation, resulting in contamination of urine and bacteria. If the cause of urine contamination is excluded, the general urine is often accompanied by the phenomenon of elevated leukocytes and epithelial cells, which may be associated with Escherichia coli, staphylococcus, streptococcus and other infections caused by cystitis, pyelonephritis and other diseases, and may also be associated with Neisseria gonorrhea infections caused by gonorrhea and so on. When there is an increase in bacteria on quantitative analysis of urine sediment, the cause needs to be clarified under the guidance of a doctor so that it can be treated aggressively.
