Hypercalciuria- childhood idiopathic
Overview
A rare disorder occurring in children for no detectable reason where excess calcium is excreted through the urine resulting in the development of stones in the urinary tract.
Symptoms
* Urinary tract stone formation * Blood in urine * Urinary tract infections * Impaired ability to concentrate urine * Enuresis
Causes
❑ inadequate intake of calcium and vitamin D, in which inadequate levels of vitamin D inhibit intestinal absorption of calcium ❑ hypoparathyroidism as a result of injury, disease, or surgery that decreases or eliminates secretion of parathyroid hormone (PTH), which is necessary for calcium absorption and normal serum calcium levels ❑ malabsorption or loss of calcium from the GI tract, caused by increased intestinal motility from severe diarrhea or laxative abuse; can also result from inadequate levels of vitamin D or PTH, or a reduction in gastric acidity, decreasing the solubility of calcium salts ❑ severe infections or burns, in which diseased and burned tissue traps calcium from the extracellular fluid ❑ overcorrection of acidosis, resulting in alkalosis, which causes decreased ionized calcium and induces symptoms of hypocalcemia ❑ pancreatic insufficiency, which may cause malabsorption of calcium and subsequent calcium loss in feces. In pancreatitis, participation of calcium ions in saponification contributes to calcium loss ❑ renal failure, resulting in excessive excretion of calcium secondary to increased retention of phosphate ❑ hypomagnesemia, which causes decreased PTH secretion and blocks the peripheral action of that hormone.
