7 Ιαν 2016 · Reading the numbers can help you achieve your best possible chance at stone prevention – which is the only reason all those lab tests were done in the first place. This article deals with calcium stones. A second one will cover uric acid stones. Your physician does this part.
11 Ιουν 2014 · A recent kidney stone analysis revealed a stone composition of 80% Carbonate Apatite (Dahllite) and 20% Calcium Oxalate Dihydrate (Weddellite). Past stones were comprised mostly of Calcium Oxalate Dihydrate.
These types of kidney stones are normally a composite of carbonate, apatite and struvite, and typically occur due to recurrent urinary tract infections (UTIs). Bacteria that occurs as a result of such infections produces ammonia, which primes chemicals in urine to form kidney stones.
Struvite stones, also called “infection stones” or Mg-NH 4 + carbonate-apatite stones, only form when urease-producing bacteria are present in the upper urinary tract, Dr. Curhan noted. Complete stone removal is required, and further stones can be prevented by preventing urinary tract infections (UTIs), he said.
10 Σεπ 2024 · The two forms of calcium phosphate include apatite (sometimes reported as carbonate apatite), which is the crystal type found in bone, or calcium hydrogen phosphate (brushite); the frequency of apatite is much greater than brushite.
The presence of infectious microorganisms in urinary stones is commonly inferred from stone composition, especially by the presence of struvite in a stone. The presence of highly carbonated apatite has also been proposed as a marker of the presence of bacteria within a stone.
