Clot in the renal vein; Occlusion - renal vein
There is no specific prevention for renal vein thrombosis in most people. Keeping enough fluids in the body to avoid dehydration may help reduce its risk.
In people who have had a kidney transplant, aspirin is sometimes used to prevent renal vein thrombosis. In people with certain chronic kidney diseases, blood thinners such as warfarin may be recommended.
