In medicine, what does it mean if there are white blood cells in a urine test?

Usually there are no blood cells in the urine as the kidney does not allow blood cells to pass into the urine and the blood has no contact with the urine in any way.|
If however there is infection of the kidneys or the bladder or if there is inflammation due to the presence of stones, immune disorders, allergies or growths anywhere along the genitourinary system, blood can get into the urine.
White cells are most likely to be seen in the urine where infection is present as these are the cells, which combat microorganisms.
For similar reasons we see white spots on the throat when we have a sore throat and white heads on our skin when we suffer from infected acne.
The white areas are collections of white blood cells, which form pus.
So your question should not be what can this cause, but what is the cause. The likely explanation is simple cystitis from a bladder infection.
The next step is to send a sample of urine away for culture and sensitivity to identify any microorganisms and to decide which antibiotic would be the most appropriate one to use in order to eradicate the infection.
Should no infection be present, further tests to measure kidney function and to outline the shape of the kidneys using X-rays may be required.
Cystoscopy to directly view the inside of the bladder using a narrow flexible telescope is another important test.
