[Myoglobinuria and acute renal failure].
Clinical and experimental studies on the development of myoglobinuria-associated acute renal failure (ARF) were reviewed. ARF developed in 30% of the cases of rhabdomyolysis. Rhabdomyolysis-associated ARF accounted for 5-10% of all ARF. The presence of dehydration or hypotension at the presentation of rhabdomyolysis seems to be a risk factor in the development of rhabdomyolysis-associated ARF. ARF occurred more frequently in the rhabdomyolysis caused by sepsis or burns. Glycerol-induced ARF in rats or rabbits has been studied to investigate the pathogenesis of myoglobinuria-associated ARF. The early decrease in inulin clearance (Cin) in glycerol-induced ARF was dependent upon the decrease in renal blood flow, but the decrease in Cin in the late phase could not be attributed to the decrease in renal blood flow. Diminished glomerular permeability and cast formation might play important roles in the decrease in Cin in the late phase of glycerol-induced ARF.
