The patient’s urinalysis results suggest that the urine bilirubin is (++++), indicating that his bilirubin metabolism has some abnormalities, and he needs to do further relevant examinations to clarify the cause of the disease. Urinary bilirubin is the unconjugated bilirubin generated after the decomposition of red blood cells, which is transformed into conjugated bilirubin in the liver and then enters the intestine to form bilirubinogen, and then passes through the hepatic and intestinal circulations, and a part of it is excreted with the urine, which is urinary bilirubin. If the patient’s test result is greater than 34.2 μmol/L, and direct bilirubin is predominantly elevated, combined with elevated alkaline phosphatase and glutamyl transpeptidase, then biliary obstruction should be considered, and ERCP should be considered for choledocholithiasis removal and placement of nasobiliary drainage. In addition, some neoplastic diseases of the bile ducts and tumors in the head of the pancreas compress the bile ducts, which can also lead to obstructive jaundice. For some patients with hepatocellular jaundice, it is mostly due to liver insufficiency caused by viral hepatitis and autoimmune hepatitis, and jaundice occurs after necrosis of liver cells, which will also affect the test results of patients. To sum up, it is recommended that patients go to regular hospitals to improve urine routine, blood routine and a series of tests, in order to clearly diagnose the disease, and then give reasonable treatment.
