You may be right. I may be crazy.
Quick internet search referenced purines as cause. The doctor explained to me why mine was diet related and said things about the oxalic acid. In short, there may be many causes.
Here a result of a quick search that appears to say there are at least two causes of gout? I lost focus after reading this, so let me know what you find.
Serum uric acid was highest in the non-stone gouty patients, followed by the gouty uric acid stone formers and gouty calcium oxalate stone patients. The high values of promoters, namely uric acid and calcium in the gouty stone patients indicate the tendency for urinary stone formation in the gouty stone patients. There is probably a correlation between gout and calcium oxalate urinary stone. We presume this mechanism is achieved through the uric acid metabolism. The findings point to the summation effect of metabolic changes in development of stone disease.
