FUNES, Patricia et al. Urinary alterations in Paraguayan lithiasic children according to nutritional status. Mem. Inst. Investig. Cienc. Salud [online]. 2019, vol.17, n.3, pp.28-33. ISSN 1812-9528.  https://doi.org/10.18004/mem.iics/1812-9528/2019.017.03.28-033.

Urolithiasis is a multifactorial disease. Recently the incidence of urolithiasis in adults and children is increasing worldwide. Changes in eating habits and an increase in the prevalence of overweight could be associated with this phenomenon. The objective was to describe the frequency of urinary alterations according to nutritional status in children with urolithiasis. This cross-sectional observational study included 104 lithiasic boys and girls divided into two groups: 68 children with normal weight and 36 children with overweight or obesity considering WHO criteria. Calcium, phosphorus, sodium, uric acid, citrate and magnesium levels were determined in 24-hour urine. The frequency of boys and girls was 51.9% and 48.1% respectively. Sixty five percent of the children presented normal weight and 34.6% of the children were overweight or obese with mean ages of 10±4 years and 8±4 years respectively. Eighty percent of the children had at least one urinary disorder, the most frequent being hypocitraturia and hyperuricosuria in both groups. The high frequency of alterations in the concentrations of urinary promoters and inhibitors of crystallization in both groups was remarkable, indicating an increased risk of recurrence.
