Introduction: Urolithiasis is a metabolic disorder with a tendency to relapse. The aim of this study was to assess the prevalence of metabolic abnormalities in patients at high risk and the impact of sex and age. Materials and methods: Descriptive study of 54 patients (37 men and 17 women),with lithiasic pathology at high risk of recurrence. The metabolic study included the measurement of calcemia, uricemia, fosfemia, parathormone, calciuria/24 h, uricosuria/24 h, fosfaturia/24 h, oxalaturia/24 h, citraturia/24 h and creatinine/24 h. The values obtained were corrected according to weight and creatinine. The test used for statistical analysis was t-student (STATA 7.0). It was considered significant p<0.05. Results: In 64,8% (35/54) of the cases a metabolic abnormality was observed and in 27,7% (15/54) there was 2 or more alterations present. The metabolic disorders most frequently observed were hypercalciuria (15/54) 27,7%, hypocitraturia (15/54) 27,7%., hyperuricemia (8/54) 14,8%. and hyperoxaluria (8/54) 14,8%. There was no significant difference in age or sex between the groups with and without metabolic abnormality. Conclusions: Most patients with recurrent lithiasic pathology or at high-risk display one or more metabolic disorders, being hypercalciuria and hypocitraturia the most frecuently encountered. In this study, there was no difference between sexes in most of the metabolic disorders, nor in its age distribution. These results demonstrate the need for metabolic studies in high-risk patients, since there are tools that allow therapeutic medical management of metabolic disorders and thus reduce the recurrence of lithiasis.
