title: [Incidence and significance of renal cell carcinoma as an incidental sonographic finding].
abstract: In 19,700 sonographies of the epigastrium of adult patients independently of the questioning of the referring physician the kidneys were involved in the examination. Thereby we found malignant space-occupations in the kidneys in 80 cases. Among these 80 patients with renal tumours 30 patients previously did not show any references to a renal tumour and did not show general signs and symptoms, which had given rise to a search for a tumour. The better prognosis of incidentally detected renal carcinomas in comparison to the symptomatic ones and the number of the sonographically detected incidental findings justify a simultaneous examination of the kidneys in each abdominal sonography, independent of the actual indication.
