Sterile pyuria
- Sterile pyuria
- Definitions
- Pyuria: the presence of 10 or more white cells per cubic millimeter in a urine specimen, 3 or more white cells per high-power field of unspun urine, a positive result on Gram’s stain of an unspun urine specimen, or a urinary dipstick test that is positive for leukocyte esterase
- Sterile pyuria: the persistent finding of white cells in the urine in the absence of bacteria, as determined by means of aerobic laboratory techniques (on a 5% sheep-blood agar plate and MacConkey agar plate)
- Bacteriuria: bacterial colony counts of more than 1000 colony-forming units (CFU) per milliliter in urine
- Causes
- Infectious etiologies
- Gynecologic infection
- Urethritis due to chlamydia, Neisseria gonorrhoeae, mycoplasma, or ureaplasma
- Prostatitis
- Balanitis
- Appendicitis
- Viral infection of the lower genitourinary tract
- Genitourinary tuberculosis
- Fungal infection
- Parasitic disease such as trichomoniasis or schistosomiasis
- Non-infectious etiologies
- Current use of antibiotics
- Recently treated urinary tract infection (within past 2 weeks)
- Presence or recent use of a urinary catheter
- Recent cystoscopy or urologic endoscopy
- Urinary tract stones
- Foreign body such as surgical mesh in the urethra or a retained stent
- Urinary tract neoplasm
- Pelvic irradiation
- Urinary fistula
- Polycystic kidney
- Rejection of a renal transplant
- Renal-vein thrombosis
- Interstitial nephritis or analgesic nephropathy
- Papillary necrosis
- Interstitial cystitis
- Inflammatory disease such as systemic lupus erythematosus or Kawasaki’s disease
