Renal ischemia
Renal ischemia refers to the lack of blood flow to the kidney. It is a serious condition that can lead to kidney damage and failure if not treated promptly.
Causes[edit | edit source]
Renal ischemia can be caused by a variety of conditions that affect the blood vessels leading to the kidneys. These include:
- Atherosclerosis: This is a condition in which fatty deposits build up in the arteries, narrowing them and reducing blood flow.
- Thrombosis: This is a blood clot that forms in a blood vessel, blocking blood flow.
- Renal artery stenosis: This is a narrowing of the renal artery, which supplies blood to the kidney.
- Hypertension: High blood pressure can damage the blood vessels in the kidneys, reducing blood flow.
Symptoms[edit | edit source]
The symptoms of renal ischemia can vary depending on the severity of the condition. They may include:
- Pain in the back or side
- Blood in the urine
- High blood pressure
- Decreased urine output
- Nausea and vomiting
- Fatigue
Diagnosis[edit | edit source]
Renal ischemia can be diagnosed through a variety of tests, including:
- Blood tests: These can measure the levels of certain substances in the blood that may indicate kidney damage.
- Imaging tests: These can include ultrasounds, CT scans, and MRIs, which can provide images of the kidneys and surrounding structures.
- Renal angiogram: This is a special type of X-ray that uses a dye to highlight the blood vessels in the kidneys.
Treatment[edit | edit source]
Treatment for renal ischemia depends on the underlying cause. It may include:
- Medication: This can include drugs to lower blood pressure, reduce cholesterol levels, or dissolve blood clots.
- Surgery: In some cases, surgery may be needed to repair or unblock the blood vessels leading to the kidneys.
- Dialysis: If the kidneys are severely damaged, dialysis may be needed to filter waste products from the blood.
