Treatment:

Treatment depends on the severity of the condition. If only one artery is involved, the second kidney may be able to filter and produce urine.

Surgery may be needed in some cases. Alternatives to surgery include a balloon angioplasty or stenting.

Medications may be needed to control high blood pressure. Renal hypertension caused by this condition may be difficult to treat. For treatment information, see the article on renal hypertension.

Complications:

Renal artery stenosis may cause chronic kidney failure if:

• It involves both kidney arteries
• High blood pressure associated with this condition is severe or continues for a long time

Additional complications:

• Malignant hypertension

Calling your health care provider:

Discuss your medical history with your health care provider to determine if you are at risk for this condition.

Decreased urine volume may be an emergency sign of kidney failure.
