[New approaches to diagnosis and treatment of cholelithiasis in young occupational groups].

Cholelithiasis was treated in 107 pilots. Cholesterol choleliths were effectively treated with ursosan. In bilirubin or calcium stones ursosan combination with shock-wave lithotripsy is more effective.

In lithogenic bile it is recommended to conduct early prophylaxis of the stones with ursodeoxycholic acid compounds.
