Alkaline citrates are used to prevent recurrent calcium stone formation. [13] [14] [15] [5] This is one of the major types of kidney stones. [16] [17] The citrate salts can increase urine citrate, which binds with urine calcium, reduces supersaturation of calcium salts, and inhibits crystal formation. [18] [8] This helps prevent kidney stones ...
Uric acid displays lactam–lactim tautomerism. [4] Uric acid crystallizes in the lactam form, [5] with computational chemistry also indicating that tautomer to be the most stable. [6] Uric acid is a diprotic acid with pK a1 = 5.4 and pK a2 = 10.3. [7] At physiological pH, urate predominates in solution. [medical citation needed]
Dosage is adjusted to maintain a reduced urinary excretion of uric acid. Serum uric acid level at or below 6 mg/100 mL is often a therapeutic goal. Hyperuricemia is not necessary for the formation of uric acid stones; hyperuricosuria can occur in the presence of normal or even low serum uric acid.
In kidney stones, calcium oxalate is the most common mineral type (see nephrolithiasis). Uric acid is the second most common mineral type, but an in vitro study showed uric acid stones and crystals can promote the formation of calcium oxalate stones. [1]
Hypocitraturia: the urine has an abnormally low concentration of citrate, which normally helps to dissolve free calcium. [41] The urine has a low pH, which stops uric acid from dissolving, leading to crystals that act as a nidus for calcium stone formation. [41]
These stones are most commonly made up of substances such as calcium, cystine, oxalate, and uric acid, as these are the substances that normally would dissolve within the urine. When they do not dissolve correctly and further build up, they will commonly lodge themselves in the urinary tract and in this case, are usually small enough to pass ...
