Leukocytes in the urine in excess of the norm, in medical terminology, leukocyturia. The presence of white blood cells in the urine usually means inflammation of the urinary system, although it can also indicate problems with the reproductive system and abdominal organs. What do urine leukocytes mean?

Leukocyturia - what does it mean?

Leukocytes in urine (leukocyturia ) in a he althy person are present in numbers only 1-3, and are normally excreted with urine. When there are more than 5 leukocytes in the field of view in the non-centrifuged urine sediment, leukocyturia is diagnosed.

The presence of an excessive number ofleukocytes in the urineis usually the result of inflammation. The number of white blood cells in the urine is increased during an infection, as they are essential for fighting a variety of pathogens (bacteria, fungi, viruses). However, their presence may also indicate many other diseases, including for cardiovascular failure.

Leukocyturiais often equated with pyuria, but it occurs when the urine contains leukocytes in an amount that causes color change, turbidity, and a specific urine odor. Pyuria is usually accompanied by bacteriuria. If the diagnosis of pyuria is without the so-called bacteriuria, we are talking about the so-called sterile pyuria.

Leukocyturia - acute and chronic urinary tract infections

The most common causes of urinary tract infections are bacteria, much less viruses, fungi, parasites, mycobacteria and chlamydia. Then there are the so-called dysuria symptoms, i.e. pain and burning when urinating, frequent urination, painful pressure on the bladder and pain in the lower abdomen after filling the bladder.

There is also a sudden pressure on the bladder and difficulties in holding urine. Occasionally, there may be pain above the pubic bone or in the lumbar region. People with upper urinary tract infections may develop fever, nausea and vomiting.

Leukocytes in urine - kidney problems

  • Interstitial nephritis is manifested by fever, dull pains in the lumbar region, skin rashes in various locations, and joint pains. In turn, urine may be red in color (haematuria) and its volume may decrease.
  • Glomerulonephritis - the chronic form of the disease is manifested by weakness, anemia,disturbances of calcium and phosphate metabolism, and even symptoms of ischemic heart disease. In turn, in the acute form, symptoms of nephritic syndrome (hematuria, proteinuria, arterial hypertension) appear, and sometimes symptoms of acute renal failure. The characteristic symptom is foaming urine, which is discolored (pink, reddish or brown).
  • Pyelonephritis usually manifests as pain in the lumbar region of varying severity. It can be unilateral or bilateral and radiate to the groin. Usually, there is also a fever or a low-grade fever, which is associated with a general malaise. There may also be abdominal pain, nausea and vomiting, as well as the so-called symptoms on duty.
  • Nephrolithiasis is characterized by colic (intermittent) pain in the lumbar region, sometimes radiating to the groin, labia, or testes, as well as nausea or vomiting, abdominal discomfort, hematuria, and dysuria. In addition, general symptoms appear, such as increased body temperature, weakness. It is worth knowing that the first symptom of nephrolithiasis is often renal colic.
