Kidney anatomy

Kidney - blood and urine flow

Clot in the renal vein; Occlusion - renal vein

The treatment is focused on preventing new clot formations and reducing the risk of the clot traveling to other locations in the body (embolization). Anticoagulants may be given to prevent formation of new clots. Bedrest or limited activity may be recommended for a brief period.

Renal vein thrombosis usually resolves over time without permanent injury to the kidneys.

• Acute renal failure (if thrombosis occurs in a dehydrated child)
• Embolization of the blood clot to the lungs (pulmonary embolism)
• Formation of new blood clots

Call your health care provider if symptoms indicating renal vein thrombosis may be present.

If you have experienced renal vein thrombosis, call your health care provider if decreased urine output, difficulty breathing, or other new symptoms develop.
