Renal artery thrombosis with deterioration of kidney function.

Renal artery thrombosis is an uncommon but serious cause of acute kidney injury that can result in permanent loss of function. It is frequently misdiagnosed due to its non-specific appearance, which can mimic renal colic and other more common causes of abdominal pain. There is no agreement on the first-line treatment and no prospective studies comparing thrombolysis, anticoagulation and embolectomy. We present a case of a patient with right renal artery thrombosis and acute kidney injury, in whom renal function was recovered with anticoagulation therapy.
