Percussion pain in the kidney area is commonly seen in two ways: first, infectious factors. Acute pus accumulation in the kidney and pyelonephritis can cause percussion pain in the kidney area. At the same time, patients also have urinary tract irritation symptoms such as urinary frequency, urinary urgency and urinary pain, and may also have symptoms such as hematuria in the naked eye, chills and high fever. The treatment is antibiotic treatment, and you should choose cephalosporin antibiotics of the third and fourth generation, such as ceftazidime, ceftriaxone sodium, and cefepime. Second, obstructive factors. Obstruction of the ureter can be seen in urological stones, tumors and other pathological causes of ureteral obstruction with hydronephrosis and signs of renal percussion pain, and surgery can be chosen to relieve the obstruction. If the patient’s physical condition does not allow, the pain can also be relieved naturally by placing a ureteral stent tube from the ureter through the ureter to drain urine, or by percutaneous nephrostomy to drain urine to relieve the pain after intrapelvic pressure.
