Patients with kidney stones may experience pain in the lower back. If kidney stones become impacted or obstructed, they may also cause pain in the upper abdomen, lower abdomen, and other areas.

Simple Low Back Pain

1. Small kidney stones: Kidney stones with a relatively small volume, such as a diameter less than 0.6cm, usually do not cause significant clinical symptoms, thus also without significant pain sensation.

2. Large kidney stones: When kidney stones are large, such as exceeding 0.6cm, they tend to get stuck in the ureter, causing severe colic pain, which may radiate to the ipsilateral inguinal region and perineum. Symptoms like nausea and vomiting may also accompany.

Pain in Other Areas

1. Upper abdomen: When kidney stones fall into the ureter and cause acute obstruction, it can lead to hydronephrosis, resulting in pain in the upper abdomen of the affected side, accompanied by swelling, nausea, vomiting, and other symptoms.

2. Lower abdomen: Some patients with kidney stones do not pay attention to their diet for a long time or drink less water, which causes urine to concentrate and form crystals that deposit in the kidneys. With the progression of the disease, kidney stones may be induced. If the stone volume is large, it may stimulate local tissues and cause pain in the lower abdomen.

3. Posterior lower back: When kidney stones enter the ureter, they can cause some damage to the surrounding mucosa, resulting in dull pain and discomfort.

It is recommended that patients with kidney stones promptly consult a urologist at the hospital. Under the guidance of a doctor, they should complete relevant examinations and undergo targeted treatment according to the doctor's advice. In addition, patients should also pay attention to a reasonable diet, mainly focusing on light foods. They can eat fresh fruits and vegetables, and avoid eating too much greasy or spicy food to prevent worsening of the condition.
