If a male patient has lower back pain with hematuria, it should be considered to be caused by kidney stones or ureteral stones, mainly because the stones damage the mucous membrane and blood vessels of the renal pelvis and ureter, resulting in hematuria. At the same time, the stone stimulates the ureter and causes spasm of the ureter, which leads to pain in the lower back. If a stone is diagnosed to be the cause of the pain, it needs to be treated with antispasmodic and analgesic treatment and, if necessary, surgery. Another condition is seen in tumors of the kidney, which will bleed after rupture, and if the bleeding is relatively large, blood clots will be formed, which will block the ureter and also cause significant back pain. Ultrasound, CT and other examinations are needed to clarify the diagnosis. If the diagnosis is confirmed to be due to tumor, timely surgery is needed to deal with it.
