Egg protein can cause kidney stones?

Yes: Limit animal protein: eating too much animal protein, such as red meat, poultry, eggs, and seafood, boosts the level of uric acid and could lead to kidney stones. A high-protein diet also reduces levels of citrate, the chemical in urine that helps prevent stones from forming. If you’re prone to stones, limit your daily meat intake to a quantity that is no bigger than a pack of playing cards.

Egg protein: Egg protein itself will not promote kidney stones. Animal protein from muscle will promote kidney stones. Egg protein is pH neutral and is not going to release as much calcium from bone as muscle protein, which is acid and thus requires bone buffering after ingestion.
