Abstract

We report a rare case of bilateral renal infarction resulting in acute renal failure in a previously healthy 26-year-old soldier. The patient presented with an abdominal pain and bilateral costovertebral angle tenderness. Laboratory studies showed elevated serum creatinine, mild leukocytosis, and increased lactate dehydrogenase. Contrast-enhanced computed tomography showed multiple perfusion defects in both kidneys with wedge-shaped infarction in right kidney. Kidney biopsy performed in the left kidney revealed microinfarction. Comprehensive work-up did not reveal any specific causes or risk factors except smoking, and the infarction was considered to be idiopathic. He emphasized that he received extremely strenuous military training several days before he came to the hospital. He was treated with low molecular weight heparin with significant improvement in renal function. Further studies are needed for the characterization of idiopathic renal infarction in previously healthy individuals and evaluating the mechanisms including strenuous physical activity on the renal blood flow.
