Pyuria: Causes & Reasons

Possible Causes for Pyuria

In most cases, when true UTI has been reported to occur in the absence of pyuria, the definition of pyuria has been at fault. [pediatrics.aappublications.org]

Pyuria is nearly always present. [microbiologybook.org]

Therefore, a finding of pyuria by no means confirms that an infection of the urinary tract is present. The absence of pyuria in children with true UTIs is rare, however. [pediatrics.aappublications.org]

Acute Cystitis

(leucocytes) can occur with other febrile illnesses, so pyuria alone on dipstick/microscopy does not confirm UTI Pyuria may be absent in early infection or very young children [rch.org.au]

Acute Pyelonephritis
