Kidney Scan

Renal Scan

Why It Is Done

A kidney scan is done to:

• Check the blood flow through the kidneys. normal 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.
• Detect an obstruction in the kidney or ureter, such as from a kidney stone.
• Detect growths in the kidneys (rare).
