Abstract

Renal cortical necrosis (RCN) is a relatively rare cause of acute renal failure. In the past, the incidence of RCN was more higher in obstetrical patients than in non-obstetric patients. But during the last 15 years, the prevalence of RCN in non-obstetric patients have overwhelmed the obstetrical patients. Renal biopsy was an only gold standard diagnostic method for RCN in the past even though it was not performed frequently because of the serious clinical circumstances and coagulopathy generally accompanied by RCN, especially during the early period. Recently, contrast-enhanced computerized tomography was found to provide very characteristic representative findings. Therefore, the importance of contrast-enhanced computerized tomography as non-invasive diagnostic procedure during the initial phase of RCN is stressed. We report two cases of RCN which we have diagnosed early by using contrast-enhanced computerized tomography and treated by hemodialysis.
