RESUMEN
In this retrospective study, the authors precise the different aspects of 7 cases of renal papillary necrosis, hospitalized in the department of Nephrology-Hemodialysis of UHC Ibn Rochd of Casablanca between 1st January 1984 to December 1990. During these 7 years, the renal papillary necrosis constituted 5% of the annual hospitalizations. The study of age and sex-ratio showed a male predominance [7]%], with an average age equal to 31,7 +/- 12,9 years. Clinically, the most frequent signs were hematuria [100%]. The etiology has been dominated by diabetes associated with acute pyelonephritis in 71% of cases. One patient had sickle-cell hemoglobinopathy and the other had renal papillary necrosis due to the abuse of analgesics. Antibiotics has been given in cases of urinary infection. Blood transfusion has been necessary in the patient having sickle-cell hemolgobinopathy. There was an improvement in the outcome of all patients
