The main idea is that bilirubin in urine reflects the presence of conjugated (direct) bilirubin in the bloodstream. Unconjugated bilirubin, being not water-soluble, does not appear in urine.

Viral hepatitis represents hepatocellular injury that disrupts normal bilirubin processing, causing more conjugated bilirubin to spill into the blood and be eliminated in the urine. Obstructive disease blocks bile flow, so conjugated bilirubin cannot reach the intestine and is excreted in urine, leading to bilirubinuria. Hepatocellular disease in general also impairs handling of bilirubin, increasing direct bilirubin in urine as well.

Because each of these conditions can raise direct bilirubin in the urine, increased urine bilirubin is listed with all of them.
