Objective: The purpose of this study is to evaluate the diagnostic value of nitrite test in comparison with urine culture (U/C) results in patients with Urinary tract infection (UTI) symptoms.Methods: This cross-sectional study was performed on 203 patients with UTI symptoms. Middle urine sample was taken into sterile plastic containers, and simultaneously the urine sample and the nitrite...

BACKGROUND Urinalysis testing is frequently ordered in the emergency department (ED), but contamination of urine specimens limits the interpretation of results. The mid-stream, clean-catch (MSCC) procedure for urine specimen collection is recommended to decrease contamination rates, but without instructions this procedure has poor compliance. OBJECTIVE To evaluate the effectiveness of written...

OBJECTIVES Degenerative changes caused by delays in urine preservation contribute to false-negative and false-positive interpretation of urothelial disease in cytology. The aim of this study is to assess whether the delay of fixation of urine samples makes any significant difference to urine cytology and morphology, and the limit of acceptability of delay for routine use in the hospital laborat...

background: preeclampsia is a serious complication of pregnancy, and it is vital to diagnosis the condition as early as possible. proteinuria is an important symptom of preeclampsia, and repeated urine analysis to screen for the condition is part of the standard antenatal care. the purpose of this study was to determine the correlation between 4- and 24-hour urine total protein values to examin...

To investigate age-associated impairments in fluid homeostasis, 4-mo (young) and 32-mo (old) Fischer 344/BN male rats were studied before and after a dietary sodium load. Transferring young rats from a low-sodium (LS) to a high-sodium (HS) diet increased water intake and urine volume by 1.9- and 3.0-fold, respectively, while urine osmolality and plasma aldosterone decreased by 33 and 98%. Conco...

AIM The aim of this study was to underscore problems associated with the dipstick test and determination of protein concentration alone in spot-urine (P-test) compared with spot-urine protein-to-creatinine ratio (P/Cr test) and to determine whether urine collection for 24-h test was complete. MATERIAL AND METHODS Dipstick and P/Cr tests were performed simultaneously in 357 random spot-urine s...

BACKGROUND 24-h urine protein is traditionally used as a gold standard method for protein estimation. Because of the operational difficulty, there is the necessity to use rapid, convenient, and reliable method of proteinuria estimation. AIM We carried out this study to compare the two rapid methods of protein estimation: dipstick method and spot urine protein creatinine ratio (UPCR) with that...

background: the most common clinical indication of aminoglycosides (ag) is the treatment of serious gram?negative infections.the aim of this study was to evaluate plausible effects of atorvastatin on the biomarkers of acute kidney injury (aki) in patients receiving amikacin. materials and methods: in this double?blinded randomized clinical trial, fifty patients (25 in each group) receiving amik...
