Abstract
1. The evaluation of renal masses has become an increasingly important topic because of the increasing incidence of kidney cancer, the improved cure rate of renal carcinoma with the proper preoperative diagnosis, and the proliferation in renal mass diagnostic methodology. 2. A variety of benign entities can produce an abnormal renal mass with attendant difficulties in being distinguished from malignant neoplasms. Among these benign lesions are: simple renal cysts, polycystic kidneys, congenital variations in renal size and shape, segmental renal hypertrophy, renal infarcts, intrarenal hematomas, renal hamartomas, renal leiomyomas, renal adenomas, renal angiomas, renal fibrolipomatosis, hydronephrosis of a duplicated collecting system, renal abscesses, and xanthogranulomatous pyelonephritis. 3. Nephrotomography, nephrosonography (ultrasound), adrenalin renal arteriography, selective magnification renal arteriography, renal venography and cavography, lymphangiography, renal scintillation scanning, abnormal levels of enzymes in blood and urine, immunologic studies (circulating antibodies and tumor-associated antigens), percutaneous needle aspirations, and retrograde renal brushing have all increased the diagnostic accuracy of determining the etiology of renal masses. None of these diagnostic procedures is infallible. A judicious combination of procedures gives the most reliable diagnostic results. 4. A search continues for (a) chemical agent(s) or a chemical profile in the blood or urine which is (are) specific for renal carcinoma, but as yet this is an investigational area and not a practical clinical reality.
