If the kidney hurts when pressed and cannot be relieved after rest, it is recommended to further go to the hospital to identify the cause. The most common causes are urinary tract infection, urinary tract stones and renal occupancy. The diagnosis can be clarified by checking liver function, kidney function, blood routine, urinary routine and urinary ultrasound. If accompanied by obvious urinary frequency, urinary urgency, urinary pain, lumbar soreness and discomfort such as chill and fever, urinary tract infection is considered more likely, usually upper urinary tract infection, which needs to be treated with antibiotics for two weeks. If the pain is caused by a stone, it is usually obvious when the stone is moving and can be slightly relieved by bending at the waist and knee position, so lithotripsy is needed if necessary. If the pain is caused by renal occupancy, it is usually vague pain in the kidney area, and needs to be investigated whether it is primary kidney tumor or secondary, and if necessary, surgical treatment.
