The kidney is one of the important organs of the human body, and its physiological anatomical location is on both sides of the human vertebral body, close to the posterior abdominal wall. There are many clinical diseases that can cause patients to have kidney pain symptoms, such as kidney stones, ureteral stones, hydronephrosis, pyelonephritis, etc. The pain site can be the location where the kidney is located, or it may be radiating pain from other parts. 1, low back: the typical site of pain in the kidney area is in the low back, located on both sides of the spine, at the corner of the rib cage, such as pyelonephritis, which can cause percussion pain in the low back. In addition, acute diseases of the kidney such as urinary stones and acute interstitial nephritis also often present painful symptoms in the lower back, and may be accompanied by vomiting and other uncomfortable symptoms; 2. Upper abdomen: when kidney stones and ureteral stones appear, patients may feel vague pain in the lower back or upper abdomen depending on the site of stone activity, and some patients have severe and unbearable pain, requiring immediate medical attention and lithotripsy through extracorporeal shock wave lithotripsy and other methods for Lithotripsy treatment; 3. Others: When acute complete obstruction occurs in the ureter, renal pelvis junction or ureter, renal colic will occur, which can cause paroxysmal pain and may also be accompanied by sweating and vomiting. The pain may gradually radiate to the lower abdomen, bladder area and inner thighs, testicles and other areas. In addition to the above, when lumbar spine disease or lumbar strain occurs, it can also cause pain in the lower back, and some people may confuse it. At this time, it needs to be distinguished from kidney pain, which is located relatively high, where the back of the waist meets, while in cases such as lumbar spine disease or lumbar strain, the pain is located relatively low, in the lower back. When kidney pain occurs, patients need to go to the hospital to clarify the cause through urine and blood tests, ultrasound and other related examinations, and then carry out targeted treatment, such as medication and surgery, to reduce body damage. At the same time, patients should take sufficient rest and avoid staying up late so as not to affect their body recovery.
