De Ruysscher C, et al. - Ninety-seven children with the first episode of urolithiasis between 1998 and 2016, followed at Ghent University Hospital initially and at least one-year follow-up, were involved in this analysis in order to recognize risk factors related to recurrent kidney stones in a pediatric cohort in a Belgian tertiary center. BMI > 85th percentile and asymptomatic stones at primary presentation were related to 1.8 and 0.1 times lower risk of recurrent stones, respectively, in the univariate analysis. On the contrary, the tenfold greater risk was caused following immobilization and the requirement for technical intervention was related to a 3.2 times higher risk of developing recurrent stones. Only BMI > 85th percentile was correlated to a 15-fold lower risk of recurrence of stone, on multivariate analysis. Hence, BMI > 85th percentile and asymptomatic stones are related to a lower risk of stone recurrence, out of all the factors examined in this cohort. Conversely, from an intense follow-up following the first episode of urolithiasis, immobilized individuals and those who need technical intervention at the primary presentation could take advantage.
