Renal infarction after aerobics

Renal infarction is most frequently due to emboli from the heart or aorta. Other causes include atheromatous disease, renal artery aneurysm, vasculitis, hypotension, hypercoagulable states, aortic dissection, and major trauma. Most renal infarctions are segmental. The extent of disease is dependent upon the size and number of renal vessels involved, coexistent renal disease, and collateral circulation. Flank pain, fever, leukocytosis, hematuria, renal failure, or hypertension may suggest the diagnosis, but these findings are nonspecific and diagnosis will depend not only on history and physical examination, but also on the appropriate imaging tests. The type of treatment is dictated by the etiology of the infarction.
