[A rare hemopathy: urographic diagnosis (author's transl)].

A case of papillary necrosis was discovered by chance when doing a systematic urography on a black woman suffering from subacute pains in the abdomen. This radiological information leads us to the finding of two hemoglobinopathies associated with a heterozygous shate: drepanocytemia and hemoglobin C disease. Clinically this list, nearly asymptomatic, is closed up by distinctive osseous lesions, the pains in the abdomen were due to a biliary lithiasis.
