Hypocitraturia is considered a major risk factor for calcium stone formation. However, there no widely accepted reference database of urinary citrate excretion in children. The aim our study was to determine the amount eliminated urine over 24-h period pediatric cohort and an optimal unit reflecting excretion. comprised 2,334 healthy boys girls aged 2–18 years. levels were assessed by enzymatic method 24-hour expressed absolute values, as concentration, citrate/creatinine ratio, per kilogram...
There are indications that obesity and hyperuricemia may influence the formation composition of urinary stones. The aim our study was to determine effect on lithogenic risk profile in a large cohort pediatric patients. population comprised 478 children with urolithiasis 517 healthy (reference group). We studied effects by dividing patients into two groups based body mass index Z-score (patients who were overweight/obese vs. those normal weight for age) comparing groups. To profile, we...
There is conflicting evidence about the role of obesity in paediatric nephrolithiasis. This Polish study explored influence nutritional status and lipid disturbances on urinary lithogenic factors risk kidney stone formation children adolescents from three to 18 years age.We carried out serum profile evaluations 24-h urine chemistry analyses 493 overweight/obese participants (mean age 13 years) without nephrolithiasis 492 healthy normal weight sex age-matched controls.A third (33%) group had...
High fluid intake has been universally recommended for kidney stone prophylaxis. We evaluated 24-h urine osmolality regarded as the best biomarker of optimal hydration and upper metastable limit after water evaporation from sample to onset spontaneous crystallization its usefulness a new risk index that would describe an individual lithogenic potential. collected 257 pediatric patients with stones 270 controls. After volume assessment, samples were subjected reduction in vacuum rotavapor...
Hypercalciuria and hypocitraturia are considered the most important risk factors for urolithiasis. Citrate binds to urinary calcium form a soluble complex which decreases availability of ionized (Ca(2+)) necessary oxalate formation phosphate crystallization. The aims this study were assess Ca(2+) fraction in relation total calciuria, citraturia pH determine whether concentration is helpful biomarker metabolic evaluation children with urolithiasis.We collected 24-h urine samples from 123...

The article aims to find potential biomarker for the detection of tubular damage in pediatric neurogenic bladder (NB) by investigating urinary levels liver-type fatty acid-binding protein (uL-FABP). This prospective analysis was conducted on two groups: 42 children with NB and 18 healthy children. uL-FABP concentrations were measured using ELISA methods. medical charts examined determine age, sex, anthropometric measurements, activity assessment Hoffer’s scale, renal function parameters....

Introduction : A disturbed calcium-phosphate balance is an important issue for kidney stone formation in nephrolithiasis. Hypercalciuria (HC) has been proposed as essential etiology of monosymptomatic nocturnal enuresis (MNE). Objectives We may suspect that patients with MNE be at risk hence the objective this paper was to assess children using Bonn Risk Index (BRI). Patients and Methods The urinary work-up 204 (83 121 controls) included calcium (Ca), magnesium (Mg) sodium (Na) excretion,...
