[Immunosuppression for living donor renal allograft recipients].

Living donor kidney transplantation allows immunosuppression individualization based on clinical and immunological criteria. Living donor kidney transplantation allows administration of immunosuppressive drugs days before transplantation, for a better acute rejection prevention. A 3-day course of tacrolimus and a micophenolic acid derivative is recommended.

[Clinical presentation of renal cell carcinoma in renal transplant].

Objectives: To analyze the clinical presentation and therapeutic response of renal cell carcinoma (RCC) of the renal graft.

Methods: Analysis of the cases described in our centre and review of current literature.

Results: RCC has a higher incidence in transplant patients, affecting the graft in less than 10% of the cases.

[Usefulness of cytokines as surgical aggression markers in the ischemia-reperfusion syndrome and post transplant renal function in an experimental model of laparoscopic vs. open renal autotransplantation].

Objectives: To analyze the modifications induced by laparoscopic and open nephrectomies in living donor transplantation on cytokines, to evaluate operative trauma of different surgical techniques and the influence on ischemia/reperfusion syndrome and renal function.

Methods: Thirty pigs underwent left nephrectomy, 15 by laparoscopy and 15 by open approach in an experimental autotransplantation model.

Results: Serum level of IL-2, IL-6, IL-10 and tumor necrosis factor (TNF) were lower during laparoscopic than open nephrectomy: 6.

[Renal autotransplantation: a valid option in the resolution of complex cases].

Objectives: To analyze the current indications for renal autotransplantation, as well as the technical features, complications and long-term follow-up of the technique.

Methods: From 1990 to 2005 we have performed autotransplantation in 10 patients, 7 adults and 3 children. The indication was established due to vascular pedicle pathology in 8 cases and ureteral lesion in 2.

[Immunosuppression and surgical complications after renal transplantation].

Objectives: The new immunosuppressive regimens in kidney transplantation have diminished the rate of acute rejection and improved graft survival. However, the use of new agents results in the development of surgical complications. The authors analyze the incidence of such complications accordingly to the type of drug.

[The usefulness of ultrasonography and Doppler ultrasound in renal transplantation].

Objectives: The aim of the study is to analyze the usefulness of ultrasound and Doppler ultrasound for the evaluation of transplant donors and recipients, for renal transplant follow-up and for the resolution of surgical complications after renal transplant.

Methods: Abdominal ultrasound was performed in donors and recipients of renal grafts. In the recipients with vascular risk factors a Doppler ultrasound of the iliac and lower limb arteries was systematically done.
