Nephron-sparing surgery for renal tumor: a choice of treatment in an allograft kidney.

摘要

The incidence of de novo malignancies is an accepted complication of organ transplantation. Renal cell carcinoma (RCC) was 4.6% of cancers occurring de novo in organ allograft recipients compared with 3% in the general population. Less than 10% of these renal cancers affected the renal allograft. Among patients developing a renal tumor in the kidney allograft, transplant nephrectomy reduced the quality of life. For these patients for whom preservation of renal function is a relevant clinical consideration, partial nephrectomy may be considered the choice for treatment. Fifteen cases have been reported regarding conservative surgery on kidney transplant tumors. Herein we have reported three cases of renal masses in well-functioning kidney transplants that were successfully treated with nephon-sparing surgery. Our experience demonstrated that in selected patients, nephron-sparing surgery on a renal allograft represents a feasible approach for tumor removal with preservation of graft function.
