UNLABELLED The purpose of this work was to investigate if in adolescents with hyperuricemia serum levels of asymmetric and symmetric dimethylarginine (ADMA, SDMA) are increased and if their levels correlate with serum uric acid (UA). PATIENTS AND METHODS The study group consisted of 58 hyperuricemic patients aged median 16.15 Q1-Q3 (14-17). The reference(More)
PURPOSE The Bonn Risk Index has been used to evaluate the risk of urinary calcium oxalate stone formation. According to the original method, risk should be determined based on 24-hour urine collection. We studied whether the Bonn Risk Index could be measured in spot urine samples and which part of the day is most suitable for this purpose. MATERIALS AND(More)
The aim of the study was to assess serum cystatin C level in children with a congenital solitary kidney, depending on their age and compensatory overgrowth of the kidney. The study group (I) consisted of 36 children, 3-21 years of age (median 10.8 years), with a congenital solitary kidney and no other urinary defects. The control group (C) contained 36(More)
BACKGROUND Detrusor overactivity (DO) is one of the most frequent bladder dysfunctions in children up to the age of 18. Nowadays, the only way to confirm DO is by urodynamic investigation, which is an invasive procedure. Among the many mediators influencing bladder function, nerve growth factor (NGF) plays an important role. The present study was designed(More)
BACKGROUND The study was undertaken to develop a potential new markers for distinguishing minimal change nephrotic syndrome (MCNS) and focal segmental glomerulosclerosis (FSGS) in children. We hypothesized that matrix metalloproteinase-9/neutrophil gelatinase-associated lipocalin (MMP-9/NGAL) is a better marker of focal sclerosis in the glomerulus then(More)
OBJECTIVE To assess functional day-time bladder capacity (DBC) and urine osmolality in children with primary monosymptomatic nocturnal enuresis (PMNE) according to age and sex. MATERIAL AND METHODS A total of 263 children with PMNE were divided into two groups: Group I, 160 children (63 girls, 97 boys) aged 5-9 years (mean age 7.14+/-1.47 years); and(More)
UNLABELLED Pyelonephritis (PN) is frequent bacterial infections in young infants and very important because may cause parenchymal scarring. Early confirmation of bacterial infection and application the appropriate treatment before obtaining result of urine culture, reduce probability of parenchymal scarring. THE AIM OF THE STUDY To evaluate the useful of(More)
Oxalate homeostasis is a derivative of absorption and transportation in the digestive system and renal/intestinal excretion of oxalate. The objective of this cross-sectional study was to determine normative values of plasma oxalate in relation to age, gender, and body size. A group of 1,260 healthy Caucasian children and adolescents aged 3 months to 18(More)
UNLABELLED Hyperhomocysteinemia is independent risk factor of cardiovascular diseases. Similarly to nephrotic syndrome (NS) predisposes to vein thrombosis. THE AIM OF THE STUDY To evaluate serum and urinary total homocysteine (stHcy and utHcy) levels in children with the symptoms of SN, and to determine a correlation between its concentration and some(More)
