Pyuria is a condition wherein abnormal amounts of white blood cells leak to the urine. This usually causes a myriad of symptoms, such as fever and cloudy urine. However, there are cases in which the patient does not show any symptoms or hardly notice any changes in the appearance of the urine.
An assortment of factors could result in high level of white blood cells in the urine. Pyuria is treated in a variety of ways depending on the root cause. This is the reason why those who suffer from it should see a doctor and go through different laboratory tests to get an accurate diagnosis. The doctor will then design the treatment according to the result of the tests.
It is possible for pyuria to recur but from a totally different cause. It is therefore very important to know other triggering factors of the condition and act accordingly to prevent it from happening again.
Causes of Pyuria
Ideally, the urine must not contain any traces of white blood cells (WBC). Something must have gone wrong if they make their appearance in the urine. WBCs are important components of the immune system to fight infection and their presence in the urine may indicate some sort of infection. There are cases though when WBC in urine does not indicate any infection.
The following may cause Pyuria:
This is the leading cause of high levels of WBCs in the urine. This develops when bacteria set in the urinary tract, kidneys or bladder and cause infection.
- STDs and other bacterial infections
Gonorrhea and Chlamydia, as well as other forms of bacterial infections like pneumonia and tuberculosis, also give rise to pyuria. Even parasitic infections like trichomoniasis can cause WBCs in the urine.
- Stones and tumors
Whether they occur in the kidneys, bladder or ureter, stones and tumors also give rise to pyuria.
- Inflammatory conditions
Inflammation stimulates the body to release histamine to dilate serotonin and blood vessels. This chemical is also important in protecting the surrounding tissues where tissue damage occurred by causing fluid to flow to the neighboring blood vessels to isolate the foreign substances. In the case of pyuria, inflammation may be present in the kidneys and other areas in the urinary system.
- Certain medicines
Glucocorticoid is one of the offending medications that have been found to cause high amounts of white blood cells in the urine.
Persons suffering from the condition experience differing symptoms which include:
- Painful urination
- Cloudy and smelly urine
- Frequent urination
- Urinary incontinence
Quite a few though do not show any symptoms at all which leads them to believe that nothing is wrong. Whether or not other symptoms appear, it is important to visit the doctor and seek help if the WBC level is high in the urine. A series of blood work and lab tests helps in getting an accurate diagnosis of the problem.
The doctor will prescribe appropriate medications to treat the cause of pus in the urine. Antibiotics are often used to fight the infection. Further evaluation may be required if the antibiotics do not work. On the other hand, treatment is not usually needed for pyuria that has been proven to be not linked to any infection.
