Gout stones can occur in the bladder and ureter?

Gout occurs in the kidney stone mainly to two factors: (1) the blood uric acid excretion through the kidneys approximately 75% -80% of the uric acid from the kidneys, about 20 percent of uric acid through the bile duct into the gut, with the feces from. Other organs such as the lung, pancreas, and so almost zero urinary acid, uric acid deposition easy in the formation of kidney stones in the kidney. Especially high concentrations of serum uric acid excretion over the ability of the kidney, kidney stones more prone to gout. (2) uric acid deposition and local environmental organizations pH (the pH value). When local, that is, when the low value of HP sedimentary formation of uric acid stones easily when local partial base, that is, at high pH values, not in some uric acid deposition. Normal blood pH value of 7.35 ~ 7.45 (neutral). Liver, lung, heart, brain and other organizations of similar pH and blood, and uric acid secretion is not the place, so difficult sedimentary formation of uric acid stones. While urine is a kidney premises, the urine pH values in the 5.5 to 6 or so, was acidic, and uric acid in urine from the mainly by the, so easy in the deposition and formation of kidney stones. Sometimes in the deposition of ureter and bladder stone formation. In a few cases, gout may also large stone vessel wall, endocardial and biliary formed, but such cases are rarely seen.
