Abstract
Urinary excretion of the most widely studied renal stone promoting (calcium, oxalate, uric acid and phosphate) and inhibiting (citrate, magnesium, pyrophosphate and glycosaminoglycans) factors, as well as the Tamm-Horsfall mucoprotein, was evaluated in 14 children with idiopathic calcium nephrolithiasis, 6 children with renal stone disease secondary to excretory malformations and 19 normal controls. No statistically significant differences in urinary excretion of promoting and inhibiting factors were found in children with idiopathic calcium nephrolithiasis but the relationship between promoting and inhibiting factors was changed as shown by an abnormal ratio of oxalate/citrate X glycosaminoglycans. This finding suggests that there is an imbalance between promoting and inhibiting factors in children with idiopathic calcium nephrolithiasis, and it is not detected by assay of each single substance.Entities:
