Hyperuricosuria is a condition in which there are high levels of uric acid in urine. It occurs in 15 - 20% of people (mostly men) with calcium oxalate stones. Urate, the salt formed from uric acid, creates the center of a crystal (nidus), around which calcium oxalate crystals form and grow.
Other causes of elevated liver enzymes may include: 1  Alcoholic hepatitis (severe liver inflammation caused by excessive alcohol consumption) 2  Autoimmune hepatitis (liver inflammation caused by an autoimmune disorder)  Celiac disease (small intestine damage caused by gluten)
Medical conditions such as hepatitis (swelling of the liver), nonalcoholic fatty liver disease, the metabolic syndrome, and alcoholic liver disease are the more common causes. Certain medicines can also cause elevated liver enzymes.
