title: [Biophysical properties of bile and urine in patients with cholelithiasis].
abstract: The electric conductivity of the hepatic bile received during and 24 hours after surgery from the drainage introduced into the common hepatic duct was studied in 94 patients with cholelithiasis. It is demonstrated that conductivity increases in cholestasis, inflammatory process in the biliary tract and depends on the hepatic morphofunctional status. The specific electric conductivity of intraoperative bile that is more than 192 S/m is considered to be criteria for the diagnosis of cholangitis. The electric conductivity of urine before and in first 4 days after surgery decreases in inflammation of the biliary tract and depends on the degree of concomitant renal dysfunction and electrolyte disturbances. There was a decrease in the conductivity of bile and urine in all studied groups. Detection of biophysical parameters of biological fluids may objectively control the postoperative period and correct treatment policy.
