%X <B>OBJECTIVE: </B>To assess the prevalence and determinants of failure to thrive (FTT) among patients with vesico-ureteral reflux (VUR) and evaluating the effects of supplementation on growth in patients with urinary solute losses.<BR><B>METHODS: </B>We retrospectively enrolled 1277 patients with VUR (mean age at diagnosis = 6.5 months). Patients with FTT were screened for renal tubular function impairment (TFI). If fractional excretion of sodium (FENa) >2% or blood bicarbonate <20 mmol/L, supplementation was provided.<BR><B>RESULTS: </B>Among 1277 patients, 56 (4.4%) had FTT. Of these, 42 (75%) presented extrarenal causes of FTT, 3 (5.4%) had chronic kidney disease (CKD), 9 (16.1%) had TFI, and 2 (3.5%) had CKD and TFI. FTT occurred in 8/208 patients (3.8%) with and in 48/1069 patients (4.5%) without (p = 0.68) recurrent urinary tract infections (UTIs). At multiple logistic regression, birthweight <10th percentile, preterm birth, TFI, identified or suspected syndromes and other diseases were predictors of FTT. Eleven (19.6%) patients with FTT had TFI; five with increased FENa and/or acidosis received supplementation and showed catch-up growth. The remaining six patients exhibited spontaneous catch-up growth.<BR><B>CONCLUSIONS: </B>FTT was found in <5% of children with VUR. It was not determined by recurrent UTIs and was mainly associated with extrarenal causes. Supplementation with sodium and bicarbonates could be useful in selected cases.
