So Calcium phyrophosphate causes pseudogout (rhomboid crystals, weakly birefringent under polarized light and blue when parallel to the light, as opposed to monosodium urate crystals that produce gout and crystals are yellow when parallel). Great.

Calcium phosphate on the other hand, causes radiopaque kidney stones, and urine crystals are wedge-shaped prisms.

Question is:

Are both the same or significantly different compounds? i.e.: is pseudogout associated with higher risk of kidney stones, or kidney stones associated with higher risk of pseudogout?
