Renal Vein Thrombosis

Renal vein thrombosis is the formation of a blood clot within the vein that drains the kidney, which impedes the outflow of blood from this organ and can affect its function.

Common symptoms: pain in the flank or lower back, blood in the urine, or swelling; sometimes the condition is silent and is detected in tests done for another reason.

Common causes: it is associated with kidney diseases that alter clotting, with states that favor clot formation, and with significant dehydration.

Which specialist treats it? Its evaluation involves the nephrologist, the angiologist, and the vascular surgeon, and in acute cases the emergency physician. If you have intense lower back pain or blood in the urine, the prudent step is to seek timely medical evaluation to investigate its cause.
