ABSTRACT –
Renal Artery Stenosis is the contraction of arteries that carry blood to kidneys (renal arteries) by preventing kidneys to get oxygen-rich blood. It needs adequate blood to filter waste products and remove excess fluids. The reduced blood flow increases blood pressure in the whole body and injures kidney tissues.

COMPLICATIONS –
- Elevated blood pressure
- Breathing problems
- Kidney failure resulting into kidney transplant and dialysis
- Fluid retention in legs
DIAGNOSIS –
- Physical Examination
- Blood and Urine tests
- Renal Arteriography
- Magnetic Resonance Angiography (MRA)

- Doppler Ultrasound
TREATMENT –
- Medications such as beta and alpha beta blockers, calcium channel blockers, diuretics
