Urine examination showing elevated leukocytes and erythrocytes suggests the presence of infection or bleeding lesions and requires further examination to clarify the specific disease.1. If urine routine reveals high leukocytes and erythrocytes, but the urinary system ultrasound is normal in performance, the diagnosis of urinary tract infection is confirmed. Because of the local mucous membrane congestion and bleeding after infection, there will be an elevated red blood cell count. Patients mostly have symptoms such as urinary frequency, urinary urgency, painful urination, lumbago, and small abdominal cramps, which require anti-infection treatment.2. If the urinalysis is abnormal, but the urinary system ultrasound reveals lesions such as stones, tumors, and polyps, it suggests the presence of related pathologies. This is due to the combination of stones or tumors, polyps, and other infections, resulting in an elevated white blood cell count. Further evaluation of the condition is required and surgical treatment is performed if necessary.
