[Asynchronic bilateral renal cell carcinoma: Radical and in situ hypothermia nephron sparing surgeries].

Objectives: To present the double action a urologist has to consider in front of a Renal cell carcinoma (RCC); on one hand, when the normality of the contralateral kidney is stated and, on the other hand when, forced by the existence of the tumor in a solitary kidney, it is mandatory to perform a surgical technique to preserve renal function.

Method: The case of a 43 year-old patient, diabetic who in 1982 underwent left radical nephrectomy for RCC diagnosed during a diagnostic work up for hypertension (HTA). Ten years later an upper pole renal tumor is found in the remaining kidney.

[Second transplant into the same iliac fossae: The importance of first transplant location].

Objectives: To report our personal experience in the reusability of the iliac fossa for renal transplantation (RT) when there are not more favorable options.

Methods: Of a total of 645 kidney transplantations, which include 52 living-donor transplantations, and three combined kidney-pancreas ones, we have selected seven, in six patients, in whom the same iliac fossa of a previous RT was reused.

Results: The cases reported were preceded by renal grafts placed on lumbariliac position, as Gil Vernet described at 1964, varying the classic situation.
