The causes of high urine sediment leukocytes are as follows: 1. The presence of urinary tract infections and the presence of more pathogenic microorganisms in the urine after infection. At this time, the human body’s white blood cells will converge to the urine and engulf the relevant pathogenic microorganisms, and a high number of white blood cells will appear when the urine sediment is examined. In this case, the patient has symptoms of urinary tract irritation such as frequent urination, urinary urgency, and painful urination, and further urine culture tests are needed to clarify the specific infecting bacteria.2. If there is urine contamination, a high white blood cell count can occur. If the process of urine retention, contamination of the utensil or urine left for a long time, urine corruption or bacterial growth in the urine, then there will be high white blood cells. 3, if suffering from vulvar infections, such as male foreskin, glans infection, female gynecological infections, etc., there will be a high number of white blood cells in the urine, because of vulvar or gynecological and other related diseases, resulting in urine contamination.
