Normal values for urinary amylase are typically 100-300 U/L, with normal ranges varying slightly with different tests and reagents. Urine amylase 700+ is a more severe level and is not recommended for discharge. Elevated urine amylase can be seen in acute and chronic pancreatitis, pancreatic cancer, pancreatic injury, cholecystitis, cholangitis, acute peritonitis, cirrhosis of the liver, mumps and other diseases. When the patient has severe pancreatitis and pancreatic cancer, there will be exponential elevation of urinary amylase, and with the relief of pancreatitis, the urine secretion will be gradually reduced, when the urinary amylase is more than 700, it indicates that the patient still has severe pancreatitis, and at this time it is not recommended to be discharged from the hospital, and the treatment will be delayed due to the recurrence of pancreatitis after being discharged from the hospital. In addition, when the patient’s urinary amylase is more than 700, must pay attention to the diet, try to choose fluids or semi-fluids, avoid greasy food intake, to reduce the food stimulation, resulting in the recurrence of pancreatitis, must be prohibited from alcohol, avoid staying up all night, to promote the recovery of the pancreas.
