High bilirubin in cholecystitis is not usually associated with urinary occult blood 2+, which is the result of different causes in the two systems. The excretion of bilirubin is impeded in cholecystitis, which can lead to high bilirubin. There are many reasons for urinary occult blood 2+, the common ones are urinary tract infection, glomerulonephritis, kidney stones and so on. 1. When bile excretion is abnormal in cholecystitis, it can lead to high bilirubin. In addition, if the inflammation of the gallbladder is severe, it can also lead to elevated bilirubin when it causes inflammation of the liver. 2. Positive urinary occult blood can be seen in: (1) urinary tract infection: urinary tract infection due to inflammatory stimulation caused by urethral mucosal congestion and edema, increased permeability can lead to urinary occult blood 2+. (2) Glomerulonephritis: glomerular injury with inflammation due to various reasons may result in urinary occult blood 2+ or hematuria, which may be accompanied by proteinuria, edema, hypertension and other symptoms. (3) Kidney stones: Stones irritate or scratch the surrounding tissues, or scratch the urethra in the process of descending, which can cause bleeding and also result in urinary occult blood 2+, accompanied by pain radiating from the waist down the ureter to the bladder and even the testicles. Urine occult blood 2 + may have other causes such as kidney tumors, etc. If cholecystitis bilirubin is high with urine occult blood 2 +, should actively improve the examination to clarify the cause of the disease, standardized treatment.
