excess of calcium in the urine, such as in hypercalcemia or in defective renal tubular reabsorption of calcium.

hypercalciuria

(hī′pər-kăl′sē-yo͝or′ē-ə)
n.
The excretion of abnormally high concentrations of calcium in the urine.

hypercalciuria

[hī′pərkal′sēyoo͡r′ē·ə]
Etymology: Gk, hyper + L, calx, lime; Gk, ouron, urine
the presence of abnormally great amounts of calcium in the urine, resulting from conditions such as sarcoid, hyperparathyroidism, or certain types of arthritis that are characterized by augmented bone resorption. Immobilized patients are often hypercalciuric. Some people absorb more calcium than is normal and therefore excrete greater than normal amounts into their urine. Concentrated amounts of calcium in the urinary tract may form kidney stones. Treatment is directed to correcting any underlying disease condition and limiting dietary intake of calcium. Also called hypercalcinuria. Compare hypercalcemia. hypercalciuric, adj.

Excretion of abnormally large amounts of calcium in urine.

hypercalciuria (hī´pərkal´sēoo´-rēə),

(hypercalcinuria), a condition in which there is an excessive increase in urinary calcium excretion. Major causes include primary hyperparathyroidism, hypervitaminosis D, excessive milk intake, metastatic malignancy, immobilization, and renal tubular acidosis. See also hypercalcemia.

hypercalciuria

excess of calcium in the urine.

absorptive hypercalciuria
caused by increased absorption of calcium from the intestine. Blood calcium levels are normal and parathyroid hormone levels are normal or low. May be caused by an excess of vitamin D or hypophosphatemia.
renal leak hypercalciuria
decreased renal resorption of calcium.
resorptive hypercalciuria
results from hypercalcemia with excessive calcium filtration and renal tubular resorption.
