[Modern aspects of diagnostics and treatment of renal infarction]

One of the causes of acute kidney injury is the renal artery thrombosis. Clinical manifestations depend on the level of thrombus. This pathology is characterized by non-specific clinical manifestations in the early period, the complexity of differential diagnosis, often delayed verification of the diagnosis and unfavorable prognosis in case of prolonged (5-7 days) anuria. There is no generally accepted protocol for the diagnosis and treatment of renal artery thrombosis. To clarify the diagnosis, intravenous urography, radionuclide renography, and contrast-enhanced computed tomography are recommended. Until recently, patients with suspected renal artery thrombosis were treated with anticoagulant therapy and renal replacement therapy with hemodialysis, which is required constantly as renal function was usually irreversibly impaired. Surgical treatment is effective only in the first hours. The outcome is often unfavorable, the probability of hemorrhagic complications is high. Due to the rare frequency of detection and verification of renal infarction, no consensus has been reached regarding the diagnosis or treatment of this condition.
