title: [The conservative surgical treatment of kidney tumors].
abstract: Seven cases are reported of patients with renal tumors in whom organ-preserving operations were performed. Two patients had only one kidney, the contralateral had been removed in the past. They had only partial resection of one third of the kidney performed. In five patients, in whom parenchymal renal tumor was accidentally detected, with normal contralateral kidney, enucleation of the tumor was performed. On histologic examination one had hypernephroma, three--adenoma with atypism, one--leiomyoangiolipoma. The size of all enucleated tumors varied from 25 to 55 mm with distinct fibrous pseudocapsule, without proliferation in it and without vascular invasion of the neoplastic process. It is assumed that patients with tumor of the only kidney when possible should be subjected to organ-preserving operation. In the event of a small encapsulated tumor and normal contralateral kidney, organ-preserving operation may be performed when there is low-grade malignancy.
