title: [Osseous metaplasia of renal medulla (author's transl)].
abstract: Bone formation in renal medulla arises from papillary necrosis and is observed almost exclusively following chronic pyelonephritis and chronic interstitial nephritis. Since papillary necrosis occurs in the early stage of chronic interstitial nephritis, this kind of osseous metaplasia has specific diagnostic significance. By means of a case report formal pathogenesis, experimental basis, clinical diagnostic considerations and prognosis of the bone formation in renal medullary parenchyma are discussed.
