Normal people only have discomfort or a slight pain when they press the right lower kidney. There is a large diagnostic value in the tenderness of the kidney area. There are three places of tenderness: one is the upper ureteral tender point, and the deep umbilicus of the rectus abdominis is deep pressed by the finger. The tenderness is positive, often suggesting that the renal pelvis or the upper ureter has lesions; The second is the middle ureteral tenderness point, with the fingers deep pressure at the intersection of the outer rectus abdominis and the anterior superior iliac spine, the obvious tenderness, often suggesting that the side of the ureter has lesions; the third is the ridge rib angle tender point, with fingers Heavy pressure on the patient's back spine 12 floating rib joint angle, if there is obvious tenderness, often suggesting kidney or renal pelvis lesions.
