If the patient’s urine results indicate that the patient has a bilirubin level of 17 μmol/L, it is most likely that the patient has an obstructive biliary tract disease that is causing the bilirubin to rise. For conjugated bilirubin, it can be excreted through the urine by the kidneys, but under normal circumstances, the amount of bilirubin in the body is low and appears as negative or weakly positive. If a patient has elevated bilirubin in the urine routine, the patient should look for elevated total bilirubin, direct bilirubin, alkaline phosphatase, and GGT in the liver function. If there is, we should consider upper abdominal ultrasound and upper abdominal MRI to determine the cause of biliary obstruction. The most common cause is the presence of bile duct stones. In the case of biliary obstruction caused by bile duct stones, the patient should be actively considered for removal of bile duct stones under ERCP and placement of nasobiliary duct for drainage. In case of tumor disease, further surgical treatment is required depending on the location of the tumor.
