[Resection of the kidney for tumor]

The experience of 159 organ-preserving operations (112 renal resections and 47 enucleations) enabled the authors to formulate basic aspects of nephron-saving operations. Renal resections are valid in one kidney affected by the tumor, the other being intact. A complex of the preoperative examinations must include selective renal pharmacophlebography to reject tumor thrombus of the intrarenal vein outside the tumor site. 10 patients were resected by the modified technique - frontal removal of a part of the kidney with the tumor. Frontal resection of the kidney (ventral or dorsal) is recommended in location of the tumor in the superior or inferior segment in tumor growth forward or backward, in cases when each millimeter of renal parenchyma is important for the patient. Regional and juxtaregional lymphadenectomy must be made in any surgery for renal cancer. Long-term outcomes of organ-saving operations should be assessed not only by tumor stage and malignancy but also by the state of the contralateral kidney.
