INTRODUCTION Treatment of end stage renal disease (ESRD) should be unitary and integrated in the various options of hemodialysis (hospital in the dialysis center in home), peritoneal dialysis (chronic ambulatory, with nighttime cycler, etc.) and renal transplant (RT). In each patient must choose the most appropriate initial therapy and for this we must evaluate the various characteristics of the patient's personal, social and labor, co-morbidity, assessment of benefits, risks, quality of life, etc.., With each option therapy. To be integrated allows passage from one to another treatment for complications, intolerance, graft rejection, etc.. The TR is successful today and for years Choice1 therapy for most causes of renal failure that is indicated. Improving quality of life by disregarding the dependence on dialysis and strict diets, increases survival of patients and treatment is more economical when compared with dialysis. It is a routine procedure and its applicability is limited by the availability of kidneys in relation to the growing demand of patients who need it. This imbalance between patients on the waiting list of TR and the availability of cadaveric kidneys expands every year. For this has been increasing donor age and used expanded criteria kidneys or kidney suboptimal heart-beating donors, etc. The TR option of living is an excellent alternative because it allows formal surgery, can be achieved in dialysis and preferably situation is indicated in young people where they are most beneficial results. This option is currently being extended to the point that in countries like the United States half of all kidney transplants are from living donors. INDICATIONS AND CONTRAINDICATIONS TR progressive success has led to an increase in the list of indications and currently there are only absolute contraindications.
is indicated in most of the diseases that progress to ESRD remained the leading causes of chronic glomerulonephritis, diabetic nephropathy and nephrosclerosis. Less common causes include chronic pyelonephritis, hereditary kidney disease, metabolic disease other than diabetes mellitus, obstructive uropathy, toxic nephropathy, etc. Some of these diseases, especially primary and some secondary glomerulonephritis may recur in the graft (focal segmental glomerulonephritis, membranoproliferative, IgA, Schönlein-Henoch purpura, hemolytic-uremic syndrome, diabetes mellitus, oxalosis, amyloidosis, etc.). . Yet rarely are contraindicated TR in these patients. Two of the most important factors to consider when accepting patients for inclusion on a waiting list of TR are age and disease associated (comorbidity), mainly cardiovascular, liver, lung or central nervous system. Until recent years, infection by human immunodeficiency virus (HIV) as an absolute contraindication, but now it is considered that in the absence of viral replication for more than 3 months, presence of CD4 lymphocytes than 200/mm3 for more than 6 months and absence of infections or tumors with stable or controlled infection with antiretroviral drugs does not contraindicate renal transplantation. STUDY pretransplant necessary to evaluate all patients with ESRD before inclusion on the waiting list for TR. It should facilitate the study as early as the glomerular filtration is about 20 ml / min because it allows the realization of renal transplantation in predialysis situation, leading to better results in both patient survival and graft in comparison with patients who have been waiting on the waiting list for kidney transplantation. The initial evaluation involves a complete medical history and physical exam along with supporting data (laboratory and imaging tests), urological and vascular assessment and extensive information to paciente2. It is convenient to carry out an initial study mandatory for all patients and complete with optional studies that require those under the criteria of each center and features for each patient (history and background, age, sex, type of nephropathy, examination findings, presence or suspicion of urological or vascular claudication type, blowing, etc.)-Table 2 -.
The patient information must be comprehensive in terms of surgical risk and complications, need for lifelong immunosuppression and risk of cancers and infections that leads, information about the possibility of a return to dialysis for various reasons mainly due to chronic rejection, information on potential benefits and risks of living donor transplantation, the need for dialysis care to get the transplant in the best possible information the overall performance and level of the center, etc. Optional studies will depend on the criteria of each center and in this special way affect the characteristics of each patient (history and background, age, sex, type of nephropathy, examination findings, presence or suspicion of urological or vascular type reflux, accidents stroke, claudication, bruits, etc.). SELECTION OF RECEIVER AND DONANTETrasplante living donor kidney Once checked in the evaluation that the candidate is suitable for transplantation should assess whether there is in the family real options for the TR live especially if the patient is young. This is an excellent therapeutic option for ESRD treatment to be based on ethical principles of altruism, the absence of coercion or financial reward, autonomy in decision making, and charity and not maledicencia3. Its use is justified by the shortage of cadaveric organs in relation to demand, low risk to the donor and better patient survival and graft. Also permits the implementation of the protocol and / or under pre-dialysis or after a short stay on dialysis which significantly reduces the morbidity associated with dialysis and character aspects of school improvement, employment, reduce costs, etc.

Employment living donor differs greatly from one country to another and some like the U.S. and Brazil account for 50% of TR made. In Spain, the world leader in the cadaver transplant activity, made a number less than 4% although there is now a policy to increase living donation to reduce waiting lists. It must meet certain legal requirements (Act 30/1979 and Royal Decree 2070/1999 of 30 December). If more than one potential donor of living would be valued donor characteristics (age, risk, difference in age and body mass between donor and recipient, and the degree of HLA and ABO compatibility). The donor will undergo a study protocol or rigorous evaluation and testing stages starting with general and cross match, leaving for later more sophisticated examinations such as angiography, CT angiography or MRI angiography. Needs to be clarified as soon as possible a contraindication as decreased creatinine clearance, proteinuria and / or hematuria, hypertension, diabetes, obesity and history of cancer, hepatitis stones or not to continue with their studies.
It is now increasingly used in laparoscopic donor nephrectomy because it offers advantages over open surgery in that it reduces postoperative pain, reduced hospital stay and recovery time as well as long-term physical sequelae. The survival results are generally excellent and more than ten years 17 to 20% to those from cadaver donors. CadáverSi donor kidney transplant recipient does not have the option of a living donor may be included on the waiting list for cadaver transplantation and the selection is usually made according to the degree of ABO and HLA compatibility.
