Hematuria is not the same as uremia; hematuria is merely a symptom with various causes such as infections of the urinary system, tumors, stones, or decreased coagulation function leading to blood in the urine. After experiencing hematuria, it is necessary to promptly visit a hospital's urology department for routine urine tests, ultrasonography of the urinary system, CT scans, urinary system imaging, or even a cystoscopy to determine the specific cause of the hematuria. Uremia, on the other hand, primarily refers to damage to kidney function, leading to decreased kidney function, which causes symptoms such as reduced urine output and localized edema in the body. If hematuria occurs or uremia is suspected, a detailed examination at the hospital's urology or nephrology department is required promptly.
