Low back pain is not the direct cause of hematuria, but low back pain can be accompanied by hematuria. The causes of low back pain accompanied by hematuria mainly include urinary tract stones, inflammation of the urinary tract, urinary tract tumors, tumors invading the tissues of the lumbar back and trauma. 1. Ureteral stones: mainly ureteral stones will scratch the ureteral wall during the downward movement of the stone, causing corresponding symptoms. 2. Inflammation of the urinary tract: urinary tract infections can cause mucosal edema and damage, which can also cause the corresponding conditions. 3. Urological tumors: the appearance of urinary tumors, such as renal cancer, renal pelvis cancer, etc., will cause local mucous membrane ulceration and encroachment of surrounding tissues, which will also cause corresponding symptoms. 4. Tumor invading the tissues of lumbar back: surrounding tumorous lesions invading the tissues of lumbar back, especially invading the ureter will also cause corresponding symptoms. 5. Trauma: Trauma directly causing kidney injury will cause blood vessel breakage, which will also lead to the corresponding conditions. Low back pain itself does not directly induce hematuria, but when there is low back pain accompanied by hematuria, you need to go to the regular hospital in time to diagnose the specific physical condition, under the guidance of the clinician to carry out standardized treatment, to avoid causing delays in the condition.
