What does a high-density shadow in the right renal cortex mean?

High-density shadow in the right renal cortex is an imaging manifestation, which is generally prone to appear in renal B-ultrasound and renal CT. It may be caused by renal parenchymal calcification, renal stones, or renal cysts.

1. Calcification: The discovery of high-density shadow in the right renal cortex through renal B-ultrasound and CT examinations is likely to be the precipitation of calcium in the renal parenchyma. It may also be a sign of gradual improvement in some diseases. If the patient has no abnormal symptoms or other discomforts, special treatment is generally not required, but more observation and regular hospital re-examinations are necessary.

2. Renal stones: If the high-density shadow in the right renal cortex appears in the renal pelvis or renal sinus, it is likely to be caused by renal stones. Patients need to adjust their diet, work, and rest. If symptoms such as urgent urination, frequent urination, and painful urination appear, or if the stones are large, surgical treatment is required immediately.

3. Renal cysts: If the patient also has bleeding, it may be a renal cyst. It is recommended to go to the hospital for a re-examination. If it is confirmed as a renal cyst, immediate surgical removal is required. Besides the above reasons, it may also be caused by renal cancer, which requires attention and active treatment.
