Can a supplement help prevent calcium phosphate kidney stones?

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.
This early study compares different “alkalinizing” medicines to see if they lower kidney stone risk in people following a carefully controlled diet. It may help those trying to prevent stones, especially if diet changes and medication together work better than diet alone.
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 if adding baking soda (sodium bicarbonate) to your current medication (Urocit-K) helps lower stone-forming chemicals in your urine. It is for people who have low citrate or uric acid stones and are already taking Urocit-K.
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 trial tests a new approach to prevent calcium oxalate kidney stones from coming back. It may help people who have had a procedure to remove stones and have a specific stone type.
