What is dx approach for renal diseases?

➢ Renal biopsy provides a specific pathological pattern or reveals non specific lesions (end stage kidney disease) ➢ To determine the disease (as a clinical entity) it will be essential to compare the anatomopathological report with the clinical and biological data. ➢ This correlation is a fundamental step which will allows us to distinguish primitive GP from secondary ones occuring in a more complexe disease ➢ Ex : crescentic pauci- immune GN can be seen in a variety of conditions including ANCA vacsulitis : in the case of an upper repsiratory tract syndrome is associated, with positive ANCA, we could propose the diagnosis of wegner granulomatosis
