When there is kidney damage or kidney disease, and the kidneys are not able to filter waste efficiently, there will likely be a rise in creatinine levels in the blood. For adults with kidney disease, dialysis is recommended when creatinine levels reach 10.0 mg/dL.
The two types of gallstones are cholesterol stones and pigment stones. Cholesterol stones are usually yellow-green and are made primarily of hardened cholesterol. They account for about 80 percent of gallstones. Pigment stones are small, dark stones made of bilirubin.
Gallstones can be divided into 2 categories: Cholesterol stones (80%) and pigment stones (20%). Most patients with gallstones are asymptomatic. Stones may temporarily obstruct the cystic duct or pass through into the common bile duct, leading to symptomatic biliary colic, which develops in 1-4% of patients with gallstones annually. Cholecystitis occurs when obstruction at the cystic duct is prolonged (usually several hours) resulting in inflammation of the gallbladder wall.
