Does pyuria indicate infection in asymptomatic dialysis patients?

Clin Nephrol. 1997 Jan;47(1):50-1.


It has been suggested that the finding of leukocyturia > 10 WBC/HPF in asymptomatic dialysis patients predicts a positive urine culture and hence indicates urinary tract infection. Seventeen asymptomatic ESRD patients contributed clean catch specimens. Nine patients had ten or more WBC/HPF. One of these grew a possible pathogen in pure culture (23% of specimens excluding those growing multiple organisms). Thus, leukocyturia is not a good marker for positive urine culture and moreover is not demonstrated to indicate infection even when positive cultures follow.
