Leukocytes, or white blood cells in normal cases present in the urine in very small quantities. Norma content of leukocytes in urine is considered to ten leucocytes per microliter (for women the rate is up to six white blood cells, for men - up to three) in the field of view after examining the fluid samples under a microscope. Elevated leukocytes in urine - any sign of inflammation.
A condition in which the number of leukocytes in urine exceeds the norm, called leukocyturia. If the number of leukocytes in the field of view in the study of urine under the microscope more than two hundred, the state called pyuria. The presence of white blood cells in the urine is determined in the analysis of urine for leukocyte esterase (an enzyme produced by white blood cells). Although the analysis is considered to be sufficiently accurate, in some cases, test results may be wrong - for example, trihomonialnye infection or vaginal discharge
The whole truth about vaginal secretions
can cause erroneous confirmation of the presence of leukocytes in urine, and a high level of acid or protein in urine, on the contrary, to conceal the presence of leukocytes in urine.
Elevated white blood cells in urine - a sign of the disease
Any deviation from the norm detection of leukocytes in urine is considered to be potentially a symptom of any disease of the genitourinary system.
The presence of white blood cells in the urine itself is only indirectly symptoms - the final diagnosis of the disease requires other tests, as above normal white blood cells in the urine can be caused by a variety of diseases. For example, elevated white blood cells in the urine
White blood cells in urine - complications are inevitable
characteristic of different types of cystitis, pyelonephritis, and various other kidney disease, urethritis, prostatitis

. Usually, the analysis of urine for white blood cells and is used to diagnose the disease and to monitor the effectiveness of treatment and - after a successful course of treatment the level of white blood cells in the urine returns to normal parameters.
Cystitis
One of the most common reasons for increasing the number of white blood cells in the urine - an ordinary cystitis, bacterial infection of the urinary tract and bladder, which is often experienced by women, at least - men. Urinalysis, including the maintenance of Bellevue blood cells - the main method of diagnosis of cystitis, which causes the characteristic symptoms such as frequent urination, pain during urination, the appearance of blood clots in the urine. The main method of treatment of cystitis - a short course of antibiotics after administration which, as a rule, the re-analysis of urine, on the basis of which the judge recovery.
Pyelonephritis
Another common reason for raising the level of white blood cells in urine - pyelonephritis, a kidney infection that causes acute symptoms. Usually, pyelonephritis - a consequence of a urinary tract infection, in the absence of proper treatment and affecting the kidneys. As cystitis, pyelonephritis - an infection of bacterial nature, which, however, is accompanied by a much more severe symptoms. Pyelonephritis can cause severe pain in the kidney area, a sharp increase in body temperature, nausea, vomiting, along with symptoms similar to the symptoms of cystitis. As well as diseases of the urinary tract and bladder, pyelonephritis taken a course of antibiotics to cure.
Urethritis
Elevated leukocytes in urine could be caused by urethritis - inflammatory diseases of the mucosa of the urethra (urethral), which often experienced by men. Urethritis can be one of the consequences of diseases, sexually transmitted diseases - such as gonorrhea, trichomoniasis. Typical symptoms of urethritis - the presence in urine of large amounts of white blood cells, discharge from the urethra, sharp cutting pain when urinating.
Hematuria
Hematuria - the appearance of blood in the urine, a symptom typical of many diseases of the urinary tract, the bladder and kidneys and causing an increase in the number of white blood cells in the urine. The cause of hematuria may be cystitis
Cystitis: urgently take action
, Various internal injuries, formation of stones in the gallbladder or kidney.
