1. METABOLIC RISK FACTORS IN CHILDREN WITH ASYMPTOMATIC HEMATURIA Francisco Rodolfo Spivacow, Elisa Elena del Valle, Paula Gabriela Rey Dr.Mohammad Reza Razavi Dr.Mohammad Mahdi Shater

2. INTRODUCTION • Hematuria is one of the most common genitourinary abnormalities in children • clinical presentations • associate signs and/or symptoms , past medical history, family history • Idiopathic or benign hematuria • Some of these patients may subsequently suffer from kidney stones with hypercalciuria , hyperuricosuria , or hyperoxaluria , with most of these having a positive family history of urolithiasis

3. INTRODUCTION • The aim of this study was to evaluate the clinical presentation, family history, and metabolic risk factors of 60 children with asymptomatic hematuria without kidney stones

4. PATIENTS & METHODS • retrospective and cross-sectional analysis • patients under 16 years of age who were referred to our institution between 1996 and 2012 for evaluation of metabolic risk factors • referred to our institution by pediatric nephrologists and came from the general population • Negative for any explained cause of hematuria(PMH, DH ,…) • Family history of kidney stones

5. PATIENTS & METHODS • Sampling • Blood sample • Urine sample Hypercalciuria (HC), i.e., excretion of >4 mg/kg/day urinary calcium Hyperoxaluria (OX), i.e., overproduction of oxalate [>50 mg/1.73 m2 body surface area (BSA)/day] in the kidneys Hypocitraturia (CiT), i.e., urinary excretion of <400 mg citrate/g creatinine Hypomagnesuria (MG), i.e. urinary excretion of <1.24 mg magnesium/kg body weight/day Hyperuricosuria (HU), i.e., urinary excretion of excess amounts of uric acid (>815 mg/1.73 m2 BSA/day).

6. RESULTS • Study • Family history of renal stone • At least one urinary metabolic abnormality was present in 49 patients, while 11 patients had no metabolic abnormality. • Befor metabolic study

7. RESULTS • Single urinary metabolic risk factors

8. RESULTS • Multiple urinary metabolic risk factors

9. RESULTS • The most common urinary risk factor was idiopathic hypercalciuria (single or associated), which was found in 43.5 % of patients, followed by hypocitraturia (single or associated), present in 31.7 %. Unduly acidic urine pH as a single abnormality was found in 10 % of this pediatric patient population.

10. RESULTS • Metabolic risk factors in children with hematuria and in pediatric kidney stone- formers

11. CONCLUSIONS • Asymptomatic idiopathic hematuria in pediatric patients may often be associated to different urinary biochemical abnormalities, similar to what is observed in pediatric kidney stone-formers. • Long-term monitoring of children with hematuria and metabolic disorders may clarify the true association with kidney stone disease. • Finally, hematuria of unknown etiology demands a biochemical risk factor evaluation that allows definition of its cause and treatment
