Chapter Five: Idiopathic Calcium Stones

You have idiopathic calcium stones. That means much of this site applies to you and your disorder. But the many articles read without a guide or sequence can confuse. You would be best off reading here, and following links as they come up. Of course you are free to...

Chapter Eight: Uric Acid Stones

Uric acid stones, to me, means not just pure uric acid stones but any uric acid in stones. If this seems fey, let me explain. Uric acid is a peculiar kind of crystal. Low urine pH causes them and treatment that raise urine pH prevent them altogether. Whether they form...
HYPERCALCIURIA

HYPERCALCIURIA

This is a foundational article for the site. High rates of urine calcium excretion (hypercalciuria) will raise calcium concentration at any given urine flow rate, and therefore raise supersaturation with the calcium stone forming salts. Genetic (‘idiopathic’) hypercalciuria, simply the upper end of the normal range, is greatly over-represented among stone formers, and idiopathic hypercalciuria (IH) is a main focus of treatment for stone prevention. As well, people with IH, stone formers or not, are at risk for bone disease. This article introduces hypercalciuria: IH itself and a few of the less uncommon named diseases that cause hypercalciuria like primary hyperparathyroidism, renal tubular acidosis, and sarcoidosis. It mentions confusing disorders such as normocalcemic primary hyperparathyroidism, secondary hyperparathyroidism, and familial hypocalciuric hypercalcemia. It also offers evidence linking specific levels of urine calcium excretion to risk of stones, a very important matter in deciding what needs to be treated.

Potassium Citrate: The Contributions of Dr. Charles Pak

Potassium Citrate: The Contributions of Dr. Charles Pak

It seems to me important to highlight not only what we can do for stone prevention, but here and there to recognize those people who have given us what we have. Charles Pak’s work was instrumental in getting potassium citrate into the real world as a treatment. He helped to establish it worked, and helped industry make a practical pill form of it. As my tribute to him I have reviewed some his most important papers on the subject. Anyone who uses the drug should care.
