A renal ultrasound is a noninvasive imaging test that uses sound waves to evaluate the kidneys and the blood vessels supplying them. It helps detect conditions such as kidney artery narrowing, cysts, blockages or changes in kidney size that may affect blood pressure and kidney function.
By providing real-time images without radiation or contrast dye, a renal ultrasound supports accurate diagnosis, treatment planning, and ongoing monitoring of kidney and vascular health.
