The results of 11 extracorporeal partial nephrectomies for neoplasm with subsequent autologous transplantation of kidney are presented. In 4 patients, resection was performed ex vivo in the presence of a large centrally located tumor in a solitary kidney. Another two patients had bilateral tumor process. In 2 patients, a large, centrally located tumor in solitary kidney was the indication for extracorporeal resection. 3 patients had elective indications for the operation. Early postoperative complications occurred in 5 patients. 3 patients had oligoanuria. One patient developed postoperative bleeding; one patient developed obliteration of the upper third of ureter. Recurrence of renal cell cancer has not been identified; the functional state of the kidney vessels and vessels of upper urinary tract was regarded as satisfactory. Good results of these operations indicate the feasibility of expanding the indications for extracorporeal organ-sparing surgery.
