Gall and biliary tract stones

DISSOLUTION OF HEPATIC AND RENAL STONES 13.9.1 Gall and Biliary Tract Stones... 

This is a stone which may be formed in secreting organs or their ducts. They have been found in the salivary gland, pancreas and prostate but are most frequently encountered in the urinary tract and gall bladder. Urinary calculi usually consist of calcium, magnesium, oxalate, carbonate or phosphate but occasionally uric acid, cystine and xanthine stones occur as a result of a metabolic disease. Cholesterol and bilirubin are found in biliary stones.
