Diagnosis of Kidney Cancer

Clinical, pathological, and roentgenologic findings were correlated in 100 cases of primary renal neoplasm. In 97 cases the diagnosis proved to be hypernephroma. The classic triad of hematuria, pain, and mass was present in only a few cases; a mass was noted in only 15 patients; and 33 patients had no clinical indications of renal disease. Laboratory data were helpful only in cases of hematuria and polycythemia. Conventional urographic studies did not distinguish renal cyst from neoplasm, but nephrotomography made the differential diagnosis with a high degree of accuracy.
