Methionine for calcium phosphate kidney stones
Part of Kidney & urinary clinical trials.
This trial tests if taking methionine supplements can lower urine pH in people with calcium phosphate kidney stones. If you have had stones that are mostly calcium phosphate and your urine tends to be less acidic, this study could help find a way to prevent new stones.
Summary written for real people, not researchers, by Clin2.

- You are between 18 and 90 years old.

This study tests a supplement called hydroxycitrate to see if it can help people who form calcium phosphate kidney stones. It may offer a new way to prevent stones from forming.
This study looks at genes in people who form calcium phosphate kidney stones. It may help doctors understand why some people make this type of stone.
This study looks at whether a specific gut bacteria called Oxalobacter formigenes can help people who form calcium oxalate kidney stones. You will eat a controlled diet and provide samples to see how your body handles oxalate, a substance that can lead to stones.
This study looks at how the body makes oxalate (a natural substance that can form kidney stones) in people who have had calcium oxalate stones. You will eat a special diet and stop supplements for a short time to help researchers understand stone formation.
This study looks at how the body handles phosphate in people with chronic kidney disease. It may help researchers understand how to better manage phosphate levels to improve health.
This study tests whether a medication that makes urine less acidic can help prevent kidney stones. It is for adults who have had stones before or are at high risk.
