Cloudy urine often is a result of precipitated phosphate crystals in alkaline urine, but pyuria also can be the cause. |
No clinical or laboratory finding distinguishes the two, though presence of pyuria makes true UTI more likely. |
Subsequently neutrophils are recruited into the urinary tract, producing pyuria. |
The specificity of the dipstick test makes it useful for identifying hematuria, pyuria, or bacteriuria. |
Findings on urinalysis may be entirely normal or may show microscopic hematuria or pyuria. |
Renal manifestations include sterile pyuria, hematuria, subnephrotic proteinuria, and renal insufficiency. |
