Causes of Hypercalciuria-associated Nephrolithiasis in Children and Adults Idiopathic hypercalciuria Increased intestinal calcium absorption - Granulomatous disease e.g. sarcoidosis - Hypervitaminosis D - Milk alkali syndrome Increased bone resorption Immobilization e.g. paraplegia and quadriplegia High animal protein diet Systemic acidosis e.g. distal renal tubular acidosis - Adrenocoicotrophic hormone or coisol excess - Primary hyperparathyroidism Decreased renal calcium reabsorption - Barret's syndrome - Chronic loop diuretic administration - X-linked hypercalciuria nephrolithiasis - Familial hypocalcemic hypercalciuria Systemic disease associated with chronic hypercalcemia - Williams syndrome - Primary hyperparathyroidism
