Kidney Scan: Why It Is Done
Content provided by Healthwise
Why It Is Done
A kidney scan is done to:
- Check the blood flow through the kidneys. Abnormal flow may mean narrowed renal arteries that can cause a type of high blood pressure called renovascular hypertension.
- See how a transplanted kidney is working.
- Evaluate the extent of kidney damage caused by an injury or infection.
- Find an obstruction in the kidney or ureter, such as from a kidney stone.
- Find growths in the kidneys (rare).
