In women, the kidneys are located on the back of the spine on both sides near the twelfth rib. The kidneys have more and more important functions in the human body, the main function is detoxification, drainage, in addition to the production of erythropoietin and vitamin D to regulate the balance of hematopoiesis and calcium and phosphorus metabolism. The human body has two kidneys, one on each side, mainly in the back of the spine on both sides, and the upper and lower position is at the lower edge of the eleventh rib, the upper edge of the second lumbar vertebra, called the kidney area. Since the right side is partially occupied by the liver, the kidney on the right side is slightly lower than the kidney on the left side. If there is pain in the kidney area, it indicates that there may be diseases in the kidney, such as acute glomerulonephritis, acute pyelonephritis, kidney stones, hydronephrosis, etc., which need to be further diagnosed together with urinary routine, kidney function, urinary ultrasound and other related tests.
