[The diagnostic and treatment problems in kidney tumors]

Experience is recorded with the diagnosis and treatment of 90 patients with tumors of the kidney and its pyelocalyx system. Of all methods of diagnosis major importance is attached to computer axial tomography. It is emphasized that the approach to the kidney, the type and scope of the operative intervention should depend on the stage of tumor development. For tumors of the pyelocalyx system it is recommended to perform nephroureterectomy, since this approach rules out the hazard of appearance of tumors in the ureter. The presence of isolated metastases is no contraindication for performing nephrectomy. Indications for organ-preserving operation should be strictly specified. They should applied in patients with single kidney, patients with bilateral tumors and patients with chronic renal failure.
