Conservative surgery was applied in 6 patients with only kidney, in 17--with unilateral cancer and contralateral kidney damaged by urological disease, in 17--with simultaneous tumorous process and in 8 patients with unilateral renal cancer and sound contralateral organ. Terms of postoperative follow-up ranged from 9 to 121 months, 14 patients have died for this period, exacerbation of cancer or metastasis being the cause of death in 9 of them. 5-year survival rate made up 64.4% although with regard to deaths related to cancer it equaled 81%. In 5 patients operated kidneys demonstrated complete functional failure due to nephrosclerosis. 5-year survival rate correlated inversely with advance of the process and was higher in unilateral lesions as compared to that of patients with bilateral tumors.
