BACKGROUND Pyuria is universally considered as essential for identifying urinary tract infections in noncatheterized patients. The utility of pyuria in the catheterized patient, to identify catheter-associated urinary tract infection (CAUTI), has not been adequately defined. METHODS We prospectively studied 761 newly catheterized patients in a university hospital; 82 (10.8%) developed nosocom...

OBJECTIVE We sought to determine factors associated with the absence of pyuria in symptomatic children whose urine culture was positive for a known uropathogen. METHODS We obtained data on children evaluated at the Children's Hospital of Pittsburgh emergency department between 2007 and 2013 with symptoms of urinary tract infection (UTI) who had paired urinalysis and urine cultures. We exclude...

Six hundred and nine urine samples were analyzed for pyuria to assess its efficacy as a predictor of bacteriuria, in catheterized patients, using different techniques of pus cells estimation. In 235 and 323 urine samples, pus cells were counted per high power field in centrifuged and uncentrifuged urine respectively, while in 51 urine samples pus cells were counted per cubic millimeter in uncen...

OBJECTIVE To study the accuracy and clinical application of the dipstick leukocyte esterase test in the detection of pyuria in young febrile children suspected to have urinary tract infection. DESIGN Prospective study. SETTING Regional hospital, Hong Kong. PATIENTS Urine samples were taken from 215 children younger than 2 years who were suspected to have urinary tract infection (fever wit...

OBJECTIVES To determine the significance of pyuria as a predictor of culture proven urinary tract infections (UTI) in neonates and to assess the frequency of urinary tract anomalies in neonates with pyuria. METHODS Prospective study conducted at the neonatal intensive care unit of a tertiary care hospital; (Liaquat National Hospital Karachi) for a period of 4 months from April 2008 to August ...

The purpose of this study was to determine whether pressing a dipstick into a pad within 2 hours of urine saturation detected pyuria as effectively as immersing a dipstick in a urine specimen. Sensitivity, specificity, and positive and negative predictive values indicated that results of the pad method were as effective as those of direct dipstick into clean-catch urine in detecting pyuria. In ...

BACKGROUND Given that YKL-40 is a known marker of inflammation, we sought to determine its association with urinary tract infection (UTI) in febrile children. METHODS In total, 44 children aged 0 to 24 months with febrile UTI and 35 age- and sex-matched controls with fever from other causes were enrolled in the study. ELISA was performed to determine the level of YKL-40 in urine collected fro...
