The infection of the kidney is more commonly called pyelonephritis. It is dangerous to leave this kind of infection untreated as it can lead to serious health issues. There are a number of reasons that lead to an infection in the kidneys. The bacteria start to spread up to the uterus from the bladder and enter into the kidney. As a result, kidney dysfunction takes place and the white blood cells start to leave the body through the urine. A kidney infection can also take place if there is a urethral or kidney stone in your kidneys. The stone slows down the passage of urine from the urinary tract. As a result, the urine that gets trapped within the kidneys starts to be infected and then WBCs populate the area. In the case of a kidney infection, you will feel pain in the flank area, burning sensation during urination, urinating more often and foamy urine. In order to treat the infection, you have to take antibiotics continuously for a prescribed time in order for it to get rid of the symptoms and fight the infection.

There are a lot of other reasons because of which you might see the white blood cells in urine. These include medications, disorders of the blood, a few kinds of cancers, such as kidney and prostate cancer.
