renal hypercalciuria

renal hypercalciuria

hypercalciuria caused by primary renal wasting of calcium, which stimulates production of parathyroid hormone to increase calcium resorption in the intestine. This type is not linked to formation of renal calculi.

Other examples of selective therapy include a thiazide diuretic for absorptive hypercalciuria or renal hypercalciuria and potassium citrate for gouty diathesis.
With renal hypercalciuria, the primary defect is in the kidney, where calcium leaks from the distal tubule, causing a transient drop in the plasma calcium that stimulates parathyroid hormone (PTH) as a compensatory mechanism.
For example, if used to treat a patient with renal hypercalciuria, whose increased intestinal absorption of calcium is a compensatory mechanism for a renal leak, it can increase the risk of negative calcium imbalance and bone disease, as well as the risk of hyperoxaluria, which could also increase the risk of stone recurrence.
