Background and purpose:Urolithiasis is one of the most common diseases of urinary tract. Abdominal colicky pain, nausia, vomiting and hematuria are the major clinical findings. Treatments including oral drugs, lithitripsy, using ureteroscope and open surgery are expensive and may result in significant complications. The aim of this research was to find medications for dissolution of urinary sto...
BACKGROUND Urinary neutrophil gelatinase-associated lipocalin (NGAL) is a novel, sensitive and specific biomarker that is rapidly released after kidney injury. It predicts acute kidney injury (AKI) in multiple clinical scenarios. We hypothesized that urinary NGAL can predict AKI after liver transplantation. METHODS Urine was collected in 92 patients undergoing liver transplantation (18 living...
BACKGROUND We recently reported that immunoreactivity of intrarenal angiotensinogen (AGT) is significantly increased in IgA nephropathy patients. Meanwhile, we have developed direct enzyme-linked immunosorbent assays to measure plasma and urinary AGT (UAGT) in humans. This study was performed to test the hypothesis that UAGT levels are increased in chronic glomerulonephritis patients. METHODS...
BACKGROUND Primary hyperaldosteronism may be associated with elevated 24-hour urinary potassium excretion. We evaluated the diagnostic value of spot urine (SU) potassium as an index of 24-hour urinary potassium excretion. METHODS We measured SU and 24-hour urinary collection potassium and creatinine in 382 patients. Correlations between SU and 24-hour collections were assessed for potassium l...
AIM To evaluate whether the urinary creatinine concentration is a reliable reference value to standardise urinary solute excretion in a spot urine sample during the first week of life. METHODS Spontaneously voided urine specimens were obtained in 48 healthy, full term neonates, aged 1 to 6 days (median 2.4) and in 168 healthy older children with a median age of 1.5 years (range 1 month to 3 y...
Background: The kidneys perform glomerular filtration, tubular reabsorption, and tubular secretion and the study of urinary excretion of some enzymes considered as a sensitive test for the detection of early stages of renal disease, particularly N-acetyl-β-D-glucosaminidase (NAG) which is a hydrolytic lysosomal enzyme present in the epithelial cells of the proximal convoluted tubule. Increased ...
Objective: Renal toxicity and ototoxicity are considered as the main side effects of aminoglycoside antibiotics, such as gentamicin. The present study aimed to investigate the effect of co-treatment by origanum vulgare extract on the gentamicin-induced renal toxicity. Methods: Adult male Wistar rats in the weight range of 200 to 250 grams were randomly assigned into four groups (n = 8): contro...
Urinary hydroxyproline excretion was measured in 130 chain saw operators aged 28-59 and in 31 normal control subjects aged 26-59 with no occupational exposure to vibration. The results measured were expressed as a ratio of hydroxyproline to creatinine. (1) No significant correlation between hydroxyproline/creatinine ratio and age was observed among normal subjects. (2) In chain saw operators gr...
