Kidney pain when squatting is generally considered to be induced by kidney stones, renal cysts, acute pyelonephritis and lumbar muscle strain, and the specific causes need to be analyzed. 1. Kidney stones: Kidney stones cause pain in the kidney area is a common phenomenon, which is related to the fact that stones can cause hydronephrosis or stones cause the ureter to be stretched. 2. Kidney cysts: the enlargement of cysts will cause the outer membrane of the kidney to be pulled, which in turn will cause pain in the kidney area. 3. Acute pyelonephritis: local inflammatory factors can also lead to pain in the renal region induced by adverse stimulation of the kidneys. 4. Lumbar muscle strain: it can also cause discomfort due to the injury of lumbar muscles, causing pain in the kidney area. It is recommended that patients with renal pain while squatting should go to regular hospitals to receive relevant examinations as soon as possible and be treated according to the examination results.
