Abstract:

A 31-year old man presented with exercise induced acute renal failure. He experienced oliguria, myalgia, hyperkalemia, elevation of blood creatine kinase, myoglobinuria and dark urine. Renal biopsy revealed mild brown granular casts and acute tubular injury. Myoglobin casts and myoglobin deposits in tubular epithelial cells were conformed by immunohistochemistry. The diagnosis of exertional rhabdomyolysis and myoglobinuria induced acute kidney injury was made.
