Gout can be stones in the ureter and bladder occurred?

Gout occurs in the kidney stone mainly to two factors: (1) excretion of uric acid in the blood through the kidneys approximately 75% -80% of the uric acid from the kidneys, and about 20% of the uric acid into the intestine through the bile duct Road, with the feces from. Other organs such as the lung, pancreas, etc. almost zero urinary acid, uric acid deposition easy in the formation of kidney stones in the kidney. Especially the excessive concentration in blood uric acid excretion over the capacity of the kidney, kidney stones more prone to gout. (2) uric acid deposition and local environmental organizations pH (the PH value). When local Piansuan, that is, when the low value of HP sedimentary formation of uric acid stones easily when partial local base, that is, high PH value, not in some uric acid deposition. Normal blood PH value of 7.35 to 7.45 (neutral). Liver, lung, heart, brain and other organizations similar PH value and blood, and acid secretion is not the place, so difficult sedimentary formation of uric acid stones. Kidney and urine is a place where urine PH values in the 5.5 to 6 about acid, and uric acid in urine from the main, so easy in the deposition and formation of kidney stones. Sometimes in the deposition of ureter and bladder stone formation. In a few cases, tophi can be in the vascular wall, endocardial and biliary formation, but such cases are rarely see.
