Renal vein thrombosis is a blood clot that develops in the vein that drains blood from the kidney.
Renal vein thrombosis is an uncommon disorder. It may be caused by:
In adults, the most common cause is nephrotic syndrome. In infants, the most common cause is dehydration.
Symptoms may include:
Exams and Tests
An exam may not reveal the specific problem. However, it may indicate nephrotic syndrome or other causes of renal vein thrombosis.
The treatment is focused on preventing new clot formations and reducing the risk of the 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:

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.
