RENAL STONES-CALCIUM STONES CAUSES
SUMMARY
1. Calcium stone causes: hypercalciuria, uric acid, hypocitraturia, hyperoxaluria, and medullary sponge disease.
2. Hyercalciuria causes: hypervitaminosis D, distal (Type 1) RTA, sarcoidosis, and hyperparathyroidism.
3. Acidosis causes hypocitraturia and also leaches calcium from the bones, resulting in hypercalciuria.
4. Calcium phosphate stones: primary hyperparathyroidism, acetazolamide, and distal (Type 1) RTA.
5. Calcium oxalate stones: high urinary oxalate, increased intake of Vit C, steatorrhoea.
