[Kidney tumors in the elderly patient over 75]

35 patients (17 females, 18 males), ranging from 75 to 92 years of age, underwent nephrectomy because they suffered from renal tumours, which in 12 cases had preoperatively a total blockage of the renal artery after angiography. A total of 27 retroperitoneal and 8 transperitoneal operations were performed. Indications as well as post-operative complications and long-term effects are dealt with. Except suppurative pyelonephritis of the residual kidney neither temporary nor permanent renal insufficiency could be observed. Even in patients of advanced age, nephrectomy will yield satisfactory longterm results and prevent the formation of metastases.
