[Bile salt nephropathy/cholemic nephrosis]

Bile cast nephropathy is a tubulo-interstitial nephropathy. Its diagnosis may be under-estimated. It develops in patients who have cholestatic jaundice, with high bilirubinemia. Bile salts are freely filtered through glomerulus. Under certain circumstances, it forms casts into the tubule and cause an acute tubular necrosis. The diagnosis evidence is histologic, but fulfilment of renal biopsy is often made difficult, because of the hemostatic abnormalities that patients with hepatocellular injury develop. The treatment is supportive and etiological. We report here the case of a patient who presented a drug-induced hepatic jaundice, complicated with acute kidney failure secondary to bile cast nephropathy. We present the histological diagnosis evidence.
