Abstract

The aim of this study was to analyze the etiology of nephrocalcinosis (NC) and whether it has any effect on growth and renal function in children. Forty-three children who were diagnosed with bilateral NC were studied retrospectively. Two neonates treated with furosemide and five premature infants were excluded from the study. The most common condition leading to NC was hereditary tubulopathies (50%). Data of 27 children who had a follow-up period of at least two years were examined in more detail. Of the 27 patients, the median age at first examination was 12 (range: 2-132) months and median follow-up time was 57 (range: 24-209) months. Thirteen of 27 (48.1%) patients had height standard deviation scores (hSDS) <-2 at presentation, and 6 (22.2%) patients who had normal glomerular function were still below -2 SDS at the last examination. Hypercalciuria was present in 25 (92.6%) patients at the first evaluation and in 6 (22.2%) patients at the last examination. The degree of NC worsened in 6 (22.2%), remained stable in 15 (55.5%) and decreased in 6 (22.2%) patients during the followup period. Chronic renal insufficiency (CRI) developed in 5 patients without there being any increase in the degree of NC. In conclusion, growth and renal function in these patients generally depend on the nature of the underlying disease but not the degree of NC.
