[Cocaine poisoning in acute renal insufficiency].

We report the case of a young man who developed acute renal failure after ingestion of cocaine wrapped in foil. We did not find either clinical or clear biochemical signs of rhabdomyolysis. The possible role of high blood cocaine level in the development of acute renal failure has been speculated and a direct vasoconstrictive effect on renal vessels followed by acute tubular necrosis has been hypothesized.
