Study of Calcium Metabolism in Idiopathic Hypercalciuria by Strontium Oral Load Test

Calcium excretion and absorption were evaluated in hypercalciuric calcium stone formers by the study of Sr2+ excretion and absorption after an oral load. Ca2+ stone formers (n = 140) were studied, and the results were compared in the 83 of them who had idiopathic hypercalciuria and in the 57 who had...

Zusammenfassung:Calcium excretion and absorption were evaluated in hypercalciuric calcium stone formers by the study of Sr2+ excretion and absorption after an oral load. Ca2+ stone formers (n = 140) were studied, and the results were compared in the 83 of them who had idiopathic hypercalciuria and in the 57 who had Ca2+ excretion within reference values. Hypercalciuric patients showed increased renal Sr2+ clearance (CRE; 5.26 +/- 0.358 vs 3.29 +/- 0.277 mL/min; P
