[Nephron sparing surgery for the treatment of renal carcinoma in a functioning graft: case report].

Objective: We present nephron sparing renal surgery as a therapeutic option for the conservative treatment of renal cancer by reporting one case of de novo renal cell carcinoma (RCC) presenting in a functioning renal graft.

Methods/results: We describe one case of de novo RCC presenting in a functioning renal graft 51 months after transplantation. Tumorectomy was carried out with a margin of normal parenchyma and the base was free of tumor.

[En bloc transplantation of pediatric donor kidneys to adult receptors].

Objectives: Analysis of all pediatric donor en bloc transplants to adult receptors performed in our department.

Methods: Retrospective analysis of 73 en bloc kidney transplants and 497 adult transplants performed in our centre from 1990 to 2004. Mean follow-up was 50.

[Renal transplant in a patient with aortobifemoral bypass].

Objectives: Over the last few years we see an increase in the number of patients with vascular disease who need a renal transplant. We discuss their management and different therapeutic options available.

Methods/results: We report the case of a female patient with history of systemic vascular disease having undergone multiple surgical procedures for it, including aortobifemoral bypass, presenting with end stage renal disease.

[Influence of recipient age on renal transplantation performed with organs coming from child donors].

Objectives: To evaluate the influence of receptor's age on the outcomes of kidney transplants with organs from donors below the age of three years and/or weighting less than 15 Kg.

Methods: We retrospectively studied the renal transplants with organs from donors below the age of three years and/or weighting less than 15 Kg performed at the Hospital Clínico San Carlos between 1991 and 1999. Receptors were divided into two groups depending on the age at the time of transplantation; group I included patients younger than 50 years and group II patients older than 50.

[Effect of recipient age on transplants performed using organs from donors in asystole].

Objectives: To evaluate the influence of receptor's age on the outcomes of kidney transplants with organs from non heart beating donors.

Methods: Observational study of the historic cohort of 570 kidney transplants performed at the Hospital Clínico San Carlos between 1991 and 1999. Receptor's were divided into two age groups, group 1 younger than 50 years, and group 2 older than 50 years.

[Renal transplantation in donors over 60 years of age].

Objectives: To evaluate the impact of receptor's advanced age on kidney transplant outcomes.

Methods: We reviewed all transplants performed between January 1990 and December 1999. Among 570 patients receiving grafts, 115 patients were 60 years or older at the time of transplantation.
