Abstract Background Patients with idiopathic calcium oxalate stones are advised to consume a low-oxalate diet prevent recurrence. In this study, on patients we have attempted determine the effect of content formation crystals in urine by vitro supersaturation study fresh postprandial samples and observing morphology formed using polarized optical microscopy. Methods The trial was conducted as p...

OBJECTIVE We aimed to compare serum and urinary HER2/neu levels between healthy control group and patients with non-muscle invasive bladder cancer. Additionally, we evaluated relationship of HER2/neu levels with tumor stage, grade, recurrence and progression. MATERIALS AND METHODS Fourty-four patients with primary non-muscle invasive bladder tumors (Group 2) and 40 healthy control group (Grou...

The aim was to evaluate the usefulness of urinary N-terminal fragment of B-type natriuretic peptide (NT-proBNP) measurement for predicting the presence of left ventricular hypertrophy (LVH) in 160 asymptomatic patients with essential hypertension. The urinary NT-proBNP/creatinine ratio was higher in patients with LVH than in either those without LVH (P< .0001) or control subjects (P< .0001). Mu...

introduction: since hypercalciuria is implicated in renal stone formation, random urine calcium to creatininee ratio (uca/cr) is the practical use in screening for hyperalciuria. however, due to worldwide variations in reference values for human population and difficulty of 24 hr urine collection for detection of hypercalciuria, we decided to conduct this study to determine normal confecting ra...

PURPOSE Microalbuminuria is defined as increased urinary albumin excretion (30-300 mg/day) or microalbumin/creatinine ratio (30-300 mg/g) in a spot urine sample. Although microalbuminuria is a predictor of clinical nephropathy and cardiomyopathy, few studies have investigated microalbuminuria in children with urinary tract infection (UTI). METHODS Therefore, we compared the spot urine microal...

Background: The ratio of urine protein to urine osmolality has recently been suggested as an accurate method to determine proteinuria.  Objective: We studied the correlation of urine protein to urine osmolality ratio with 24-hr urinary protein excretion. Methods: 150 children aged 0.11–17 years admitted to the Department of Pediatric Nephrology were included in this study. Early morning urine s...

Hyperthyroidism is characterized by accelerated bone turnover, caused from direct stimulation of bone cells by increased thyroid hormones. In this study, we aimed to investigate serum osteocalcin levels as a bone formation marker, before antithyroid (propylthiouracil) therapy at hyperthyroid stage and after antithyroid therapy at euthyroid stage of the patients. Twenty four hyperthyroid patient...

Chronic inflammation contributes to the development and progression of chronic kidney disease (CKD). Identifying renal inflammation early is important. There are currently no specific markers of renal inflammation. Endothelin-1 (ET-1) is implicated in the pathogenesis of CKD. Thus, we investigated the impact of progressive renal dysfunction and renal inflammation on plasma and urinary ET-1 conc...
