However, pyuria is not exclusive to bacterial infections. The presence of white blood cells, or leukocytes, in the urine is not a disease itself but a primary indicator of an underlying pathological process, most commonly an infection.
UTI Leukocyte in Urine Symptoms and What They Indicate
Microscopy provides quantitative data on the number and type of cells present, while culture is the gold standard for confirming an infection and guiding targeted antibiotic therapy. Differential Diagnosis and Associated Findings The differential diagnosis for leukocyturia is broad and extends beyond simple cystitis.
However, in patients with known risk factors for urological diseases, such as diabetes, immunosuppression, or a history of kidney stones, the presence of leukocytes is a strong signal that warrants further diagnostic evaluation to prevent complications like pyelonephritis or renal abscess formation. Concurrent findings are crucial; the presence of white blood cell casts strongly suggests pyelonephritis or interstitial nephritis, indicating renal parenchymal involvement, whereas the presence of bacteria without white cells may point toward a contaminated sample or an early infection phase.

Furthermore, sterile pyuria, where white blood cells are present without detectable bacterial growth, can occur in cases of interstitial nephritis, renal tuberculosis, or certain sexually transmitted infections like chlamydia and gonorrhea. A positive result, or pyuria, is significant when accompanied by other symptoms such as dysuria, frequent urination, suprapubic pain, or fever.
