Strong echogenic spots in the renal cortex are imaging manifestations, mainly considered as renal calcification foci, which may be caused by renal tuberculosis or chronic inflammation of the kidneys. 1. Consider renal calcification foci: in ultrasound examination, the examined tissues absorb ultrasound waves differently and show different light and dark images on the image, strong echogenic light spots in the renal cortex area suggest that the absorption degree of ultrasound waves there is high, and they are often caused by various reasons of calcification foci. 2. caused by renal tuberculosis: tuberculosis bacillus enters into the kidney and forms multiple tiny tuberculosis foci mainly in the bilateral renal cortex, which can be shown as strong echogenic light spots in the renal cortex area on the imaging, if the patient’s immune status is good and the number of infected bacillus strains is small, the early stage of renal tuberculosis can be cured by itself, and those with more serious infections are often accompanied by urinary frequency, urgency, urinary pain and symptoms such as hematuria in the final stage of the infection. 3. Chronic inflammation of the kidney: chronic inflammation of the kidney caused by various reasons can stimulate the corresponding parts for a long time, and the fibrotic repair of inflammation can also produce calcification foci, and there are strong echogenic spots in the renal cortex. It is recommended to consult a doctor in a regular hospital to find out the cause and standardize the treatment, so as to avoid the delay of the condition or the adverse consequences caused by irregular treatment.
