Nephrocalcinosis in childhood.
Charts of 16 children with nephrocalcinosis between 1990 and 1997 were reviewed. The cause of nephrocalcinosis was believed to be iatrogenic in 7 patients (43.8%) and non-iatrogenic in 9 (56.2%). Vitamin D therapy was responsible for 5 patients of iatrogenic nephrocalcinosis, and furosemide therapy for the remaining iatrogenic patients. Non-iatrogenic cases consisted of 3 patients with renal tubular acidosis, 3 patients with idiopathic hypercalciuria, and the 3 other patients with rare underlying conditions. Abdominal X-ray detected nephrocalcinosis in only 2 (12.5%) of the total 16 patients. None showed resolution of nephrocalcinosis during these years of follow-up.
