[Sarcoidosis of the kidney (author's transl)].

The sarcoidosis of the kidney frequently shows little symptoms, but leads in more progredient stages to heaviest functional deficits and uremia. Beside this genuine sarcoidosis of the kidney a nephrocalcinosis caused by the often higher blood calcium level in sarcoidosis patients can occur. Its cardinal manifestation is a nephrolithiasis. Seldom in sarcoidosis patients a glomerulonephritis following to humoral immune reactions is appearing. A case of genuine sarcoidosis of the kidney with typical course and extended functional deficit, improved by intensive therapy with corticosteroids and immunosuppressiva is reported.
