Renal Vein Thrombosis Overview
Learn About Renal Vein Thrombosis
Renal vein thrombosis is a blood clot that develops in the vein that drains blood from the kidney.
Blood clot in the renal vein; Occlusion - renal vein
Renal vein thrombosis is an uncommon disorder. It may be caused by:
- Abdominal aortic aneurysm
- Hypercoagulable state: clotting disorders
- Dehydration (mostly in infants)
- Estrogen use
- Nephrotic syndrome
- Pregnancy
- Scar formation with pressure on the renal vein
- Trauma (to the back or abdomen)
- Tumor
In adults, the most common cause is nephrotic syndrome. In infants, the most common cause is dehydration.
Symptoms may include:
- Blood clot to the lung
- Bloody urine
- Decreased urine output
- Flank pain or low back pain
The treatment helps to prevent the formation of new clots and reduces the risk of clot traveling to other locations in the body (embolization).
You may get medicines that prevent blood clotting (anticoagulants). You may be told to rest in bed or cut down on activity for a short time.
If sudden kidney failure develops, you may need dialysis for a short period.

Renal vein thrombosis most often gets better over time without lasting damage to the kidneys.
Complications may include:
- Acute renal failure (especially if thrombosis occurs in a dehydrated child)
- End stage renal disease
- Blood clot moves to the lungs (pulmonary embolism)
- Formation of new blood clots
Contact your health care provider if you have symptoms of renal vein thrombosis.
If you have experienced renal vein thrombosis, call your provider if you have:
- Decrease in urine output
- Blood in the urine
- Breathing problems (due to blood clot moving to your lung called pulmonary embolism)
- Other new symptoms
In most cases, there is no specific way to prevent renal vein thrombosis. Keeping enough fluids in the body may help reduce risk.
Aspirin is sometimes used to prevent renal vein thrombosis in people who have had a kidney transplant. Blood thinners such as warfarin may be recommended for some people with chronic kidney disease.
