Hepatolithiasis is a medical condition that refers to the presence of stones (calculi) in the liver or bile ducts. There are several synonyms for the term hepatolithiasis, including hepatic calculi, intrahepatic calculi, bilirubin stones, and biliary calculi. These stones are small, hardened deposits that form in the liver or bile ducts due to the accumulation of bile salts, cholesterol, and other substances. Hepatolithiasis can lead to various symptoms such as abdominal pain, nausea, vomiting, and jaundice if left untreated. Treatment options include surgery to remove the stones, lithotripsy to break them into smaller pieces, and medication to dissolve them over time.
