Overview

Pyuria is a urinary condition characterized by a high number of white blood cells in the urine. It is generally characterized as the presence of 10 or more white blood cells per cubic millimeter in a sample of urine, 3 or more white cells per high-power field of unspun urine, a positive result on Gram's staining of an unspun urine specimen, or a urinary dipstick test that is positive for leukocyte esterase. Pyuria most commonly occurs in urinary tract infections (UTI) and/or sepsis. Other causes include sterile pyuria, STDs, pneumonia, interstitial cystitis, kidney stones, pelvic infections and urinary fistulas. Long-term usage of some medications, including aspirin, diuretics, nitrofurantoin, PPIs and NSAIDs, induces pyuria. There may be visible changes in the urine, which may appear cloudy or thick or look like pus.

Life-threatening causes of pyuria include

Common Causes

Diagnosis

Shown below is an algorithm summarizing the diagnosis of pyuria.[2]



 
 
 
Patient with Pyuria
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Patient with pelvic pain, urinary
symptoms and urethral symptoms
 
Patient with fever, systemic
symptoms, urinary symptoms,
abdominal or pelvic pain
 
 
 
 
 
 
 
 
 
 
 
 
Evaluate for: STDs, Prostatitis, PID
 
Reassess for bacterial infection
by means of aerobic and
anaerobic culture
 
 
 
 
 
 
 
 
 
 
 
 
If not detected, consider:
Urinary stone,
Foreign body,
Interstitial cystitis,
Bladder tumor,
Schistosomiasis
 
No bacteria detected
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Evaluate for: Tuberculosis
If patient is a immigrant
from tuberculosis endemic country
Fungal infection
If patient is immunocompromised,
check for candida, aspergillus or
cryptococcus infection
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If no infection detected, consult
with infectious disease
specialist or nephrologist
