Abstract
BACKGROUND During the past few years, there has been renewed interest in the use of expanded criteria donors (ECD) for kidney transplantation to increase the numbers of deceased donor kidneys available. More kidney transplants would result in shorter waiting times and limit the morbidity and mortality associated with long-term dialysis therapy. STUDY DESIGN Systematic review of the literature. SETTING & POPULATION Kidney transplantation population. SELECTION CRITERIA FOR STUDIES Studies were identified by using a comprehensive search through MEDLINE and EMBASE databases. Inclusion criteria were case series, cohort studies, and randomized controlled trials assessing kidney transplantation in adult recipients using ECDs. PREDICTOR A special focus was given to studies comparing the evolution of kidney transplantation between standard criteria donors (defined as a donor who does not meet criteria for donation after cardiac death or ECD) and ECDs (defined as any brain-dead donor aged > 60 years or a donor aged > 50 years with 2 of the following conditions: history of hypertension, terminal serum creatinine level >or= 1.5 mg/dL, or death resulting from a cerebrovascular accident). OUTCOMES Criteria used to define and select ECDs, practice patterns, long-term outcomes, early complications, and some patient issues, such as selection criteria and immunosuppressive management. RESULTS ECD kidneys have worse long-term survival than standard criteria donor kidneys. The optimal ECD kidney for donation depends on adequate glomerular filtration rate and acceptable donor kidney histological characteristics, albeit the usefulness of biopsy is debated. LIMITATIONS This review is based mainly on data from observational studies, and varying amounts of bias could be present. We did not attempt to quantitatively analyze the effect of ECD kidneys on kidney transplantation because of the huge heterogeneity found in study designs and definitions of ECD. CONCLUSIONS Based on the available evidence, we conclude that patients younger than 40 years or scheduled for kidney retransplantation should not receive an ECD kidney. Patients 40 years or older, especially with diabetic nephropathy or nondiabetic disease, but a long expected waiting time for kidney transplantation, show better survival receiving an ECD kidney than remaining on dialysis therapy.

Abstract
Kidneys from old donors after cardiac death (DCD) may increase the donor pool but the prognosis of these kidneys is unsatisfactory. To improve these results, we retrospectively evaluated the diagnostic utility of published selection algorithms for old donor kidneys. We studied all DCD kidney transplantations between January 1, 1994 and July 1, 2005 at our institution (n = 199). Selection algorithms were evaluated in the subset of kidney transplantations from donors aged 60 years or older (n = 52). For histological assessment of kidney biopsies, glomerulosclerosis, tubular atrophy, interstitial fibrosis and vascular narrowing were blindly scored. Functional kidney weight was calculated as renal mass multiplied by the fraction of nonsclerosed glomeruli. Graft function and survival of kidneys from DCD aged 60 years or older were inferior to those from younger DCD. Histological scores were associated with kidney function and graft survival of old DCD kidney transplantations. Functional kidney weight was associated with kidney function but not graft survival, while donor glomerular filtration rate (GFR), donor age and machine perfusion characteristics were associated with neither of the clinical outcomes of interest. We conclude that histological assessment of preimplantation biopsies may improve the selection of kidneys from old DCD and may therefore contribute to expansion of the donor pool.

Abstract
UNLABELLED No data are available on incisional hernia in renal transplant recipients using a midline incision. This study evaluated the incidence of abdominal wall incisional hernia, comparing two surgical approaches: midline and J-shaped incisions. METHODS Between 1991 and 2005, 415 consecutive patients underwent renal transplantation: between 1991 and 1997, 139 patients through a lateral incision; between 1997 and 2005, 137 of 276 renal transplant patients via a midline incision, and 139 via a J-shaped incision. We evaluated the incidence of incisional herniae in these patients. Analyzed factor risks included: age, sex, body mass index, diabetes, reoperation, lymphocele, dialysis time, underlying renal disease, and immunosuppressive therapy. RESULTS During follow-up, 15 patients of 415 transplantations were dead or lost to follow-up. Incisional herniae were identified in 12 cases of 132 (9%) between 1991 and 1997. Between 1997 and 2005 we identified 3 of 133 (2.2%) patients who underwent a midline incision and 15 of 135 (11.1%) who received a J-shaped incision (P=.005). Comparing midline and J-shaped incisions before and after 1997, the incidence reduction was significant (P=.01). Comparing the incidence among patients treated with J-shaped incision before versus after 1997, the increased incidence was insignificant (P=.6). Multivariate analysis found the most important risk factor was obesity followed by polycystic kidney disease, reoperation, wound infection, and mycophenolate mofetil therapy. CONCLUSIONS Our data showed an advantage of a midline incision. Strategies to prevent surgical complications, such as abdominal wall relaxation and poor cosmetic results, are needed; the midline incision may be a possible alternative to address this complication.

Abstract
Ipsilateral placement of double kidneys from marginal donors into older recipients may reduce the stress of the operation on the patient and allow for extension of the utility of older donor kidneys. A separate bench preparation of the kidneys is performed to aid in assessing the quality of the kidneys before placement in the recipient. Multiple renal arteries and proximal calcifications may require extracorporeal anastomosis or multiple anastomoses in the recipient depending on length and size of the renal vessels. In the recipient, the incision should allow complete dissection of the common external and internal iliac arteries. This report provides a detail of the technique used for ipsilateral placement of double kidneys.

Abstract
The majority of patients receiving a renal allograft, including a kidney from an older donor, do well. Renal transplantation from a living donor is associated with distinct advantages, including prolonged allograft survival. When live donors are not available, however, deceased donor kidneys provide suitable renal function that frequently lasts the lifetime of elderly recipients. Elderly patients who receive a kidney transplant enjoy improved survival, better quality of life, and lower medical costs than those who remain on dialysis.

Abstract
The organ shortage has led to extend the procurement to kidneys from 'marginal' donors. As a result, an increasing number of kidneys are discarded, but an extended analysis of the validity of the clinical decision to accept or decline a marginal graft remains to be determined. We have retrospectively analyzed the outcome of 170 kidney transplantations, performed in eight renal transplantation centers between 1992 and 1998. Study group included transplantation from donors accepted after refusal for poor donor or graft quality by at least two centers. Control group included 170 paired recipients from kidneys unanimously accepted by all centers. Main causes of kidney refusal included impaired donor hemodynamics (28%), abnormal pre-harvesting serum creatinine (22%), advanced age in donors (15%), and donor atheroma (14%). The 5-year patient survival (88.2% in the study group and 88.9% in controls) and graft survival (70.4% in the study group and 76.7% in controls, P=0.129) were not significantly different. Delayed graft function occurred significantly more often in the study group patients than in controls patients (63 vs 32%, P<0.0001). Primary non-functioning kidneys were significantly more frequently observed in study patients than in controls (7.7 vs 1.8%, P=0.01). Mean creatinine clearance was significantly lower in the study group patients compared with controls during the post-transplant course. Our results suggest that these initially discarded kidneys provide satisfactory survival rates despite their impaired early functional recovery and poorer long-term renal function, and therefore might be considered acceptable for transplantation in the context of organ shortage.

Abstract
The use of elderly donors has become a necessity with the increasing demand for deceased donor organs resulting in transplant centers worldwide expanding their donor criteria. We, therefore, thought it appropriate to review our experience using elderly (>60 years) brain-dead donors for kidney transplantation. We investigated the influence of donor parameters on early graft function and survival. A retrospective comparative analysis of three periods was performed: 1994 to 1998 (P1) n = 40; 1999 to 2000 (P2) n = 28; and 2001 to 2002 (P3) with n = 31 donors. Mean donor age in each period was 63.4 +/- 3.3, 64.5 +/- 3.4, and 63.8 +/- 2.7 years; mean diuresis was 473 +/- 450, 307 +/- 316, and 276 +/- 185 mL/hour; and the need for vasopressors during donor management was 81%, 85%, and 70% respectively. The number of kidney recipients was 59, 30, and 37, mean age was 49 +/- 13, 53 +/- 11 and 54 +/- 8 years, the recipient ratio of patients >60 years was 17%, 33%, and 27% respectively, and no differences among the groups in the HLA mismatch. Primary nonfunction occurred in 8.5%, 0%, and 2.8%; acute rejection ratio at 1 year was 35%, 36%, and 32%, the mean serum creatinine at 12 months was 183.7 +/- 66.0, 157.8 +/- 41.2 and 160.7 +/- 46.5 mumol/L. The 1-year graft survival was 71.2%, 91.0% and 92.0% and the 1-year patient survival 88.2%, 96.6%, and 97.2%, respectively, for periods 1, 2, and 3. There has been a considerable improvement in the 1-year graft and patient survivals. With careful donor and recipient evaluation, individualized immunosuppression, and age matching the results of renal transplantation from elderly deceased donors can be comparable to the results of the "optimal" deceased donor kidney transplantation.

Abstract
For ten years, an increase in the number of elderly patients on renal transplant waiting lists has occured. In an attempt to close the widening gap between supply and demand and because the demand for kidneys for younger patients already surpasses the supply, transplant physicians nowadays accept organs from older donors that might have been deemed inappropriate in the past. Programs of age matching between donors and recipients and of dual-kidneys transplantation have emerged. The initial results of these programs are encouraging with excellent patient and graft survival at one and three years.

Abstract
UNLABELLED Biopsy of cadaver renal allografts may aid in the assessment of marginal allografts. However, the use of this approach is not clear. This study presents the outcome of institution of a protocol for back table biopsy of renal allografts during organ procurement. METHODS Data from Lifelink Organ Donation Network records and the ANZDATA registry were analysed. RESULTS The biopsy rate of renal allografts increased from 0.8% to 15.6% (P=0.01). The discardment rate of potential renal allografts increased slightly with 1.9% being discarded based on the biopsy result and 3.8% being discarded for other reasons. Under the biopsy protocol, 28/40 (70%) of donors with renal allograft biopsies had <20% glomerulosclerosis. The incidence of both delayed graft function and non-function was higher (P=0.014 and P=0.033, respectively) for the protocol biopsied allografts compared with the other non-biopsied allografts. One-year renal allograft survival was not significantly different between the protocol biopsied allografts versus the other non-biopsied allografts. CONCLUSIONS A biopsy protocol for marginal potential renal allografts leads to acceptable allograft outcomes without significantly increasing allograft discardment.

Abstract
More and more evidence is emerging that highlights the far-reaching consequences of prenatal (intrauterine) programming on organ function and adult disease. In humans, low birth weight (LBW) occurs more frequently in disadvantaged communities among whom there is often a disproportionately high incidence of adult cardiovascular disease, hypertension, diabetes mellitus, and kidney disease. Indeed, many epidemiologic studies have found an inverse association between LBW and higher blood pressures in infancy and childhood, and overt hypertension in adulthood. Multiple animal models have demonstrated the association of LBW with later hypertension, mediated, at least in part, by an associated congenital nephron deficit. Although no direct correlation has been shown between nephron number and birth weight in humans with hypertension, nephron numbers were found to be lower in adults with essential hypertension, and glomeruli tend to be larger in humans of lower birth weight. An increase in glomerular size is consistent with hyperfiltration necessitated by a reduction in total filtration surface area, which suggests a congenital nephron deficit. Hyperfiltration manifests clinically as microalbuminuria and accelerated loss of renal function, the prevalence of which are higher among adults who had been of LBW. A kidney with a reduced nephron number has less renal reserve to adapt to dietary excesses or to compensate for renal injury, as is highlighted in the setting of renal transplantation, where smaller kidney to recipient body-weight ratios are associated with poorer outcomes, independent of immunologic factors. Both hypertension and diabetes are leading causes of end-stage renal disease worldwide, and their incidences are increasing, especially in underdeveloped communities. Perinatal programming of these 2 diseases, as well as of nephron number, may therefore have a synergistic impact on the development of hypertension and kidney disease in later life. Existing evidence suggests that birth weight should be used as a surrogate marker for future risk of adult disease. Although the ideal solution to minimize morbidity would be to eradicate LBW, until this panacea is realized, it is imperative to raise awareness of its prognostic implications and to focus special attention toward early modification of risk factors for cardiovascular and renal disease in individuals of LBW.

Abstract
BACKGROUND The living-donor and dual kidney transplantation programmes were initiated in the transplantation centre of Münster (TCM) as two approaches to compensate for the declining numbers of cadaver donor kidney transplants after the implementation of the new Eurotransplant Kidney Allocation System (ETKAS). We analysed the outcome of cadaver, living-donor and dual kidney transplantation and their effects on the waiting list in the TCM. METHODS Between January 1990 and December 2000, 1184 kidney transplants were performed in the TCM. They were subdivided into cadaver, living-donor and dual kidney transplants and retrospectively analysed in terms of the number of kidney transplants performed, waiting time and waiting coefficient. In addition four representative groups were formed to reflect donor origin (I: cadaver kidney transplants allocated by the old ETKAS, n = 180; II: cadaver kidney transplants allocated by the new ETKAS, n = 139; III: living-donor kidney transplantation, n = 59; IV: dual kidney transplantation, n = 31) and compared according to graft function (initial diuresis, creatinine, 3-year graft function), patient survival and median waiting time. RESULTS After the implementation of the new ETKAS, the number of cadaver donor kidney transplants at the TCM almost halved, but the proportion of living-donor kidney transplantations increased significantly by 12.8% and of dual kidney transplantations by 8.5%. Patients who had received kidneys from cadaver donors allocated by the new ETKAS (group II) had a better survival rate, short- and long-term function but a longer waiting time than in group I (old ETKAS). Patients with dual kidney transplants (group IV) showed the lowest survival and short-term function rate, but had long-term function equivalent to that of cadaver kidney transplants (groups I and II). Patients who had received kidneys from living donors (group III) had the best survival, and short- and long-term function rate as well as the shortest mean waiting time. CONCLUSIONS Living-donor and dual kidney transplantation proved to be functionally equivalent alternatives and successful strategies for compensating the declining numbers of cadaver donor kidney transplants.

Abstract
BACKGROUND The use of elderly donors (ED) and dual kidney transplantation (DKT) procedures have become common in clinical practice. A correct evaluation of kidneys from ED is crucial to avoid unsuccessful transplantation or the use of DKT when a single transplant (ST) would be equally successful. The aim of this investigation was to assess the role of renal biopsy (RB) in the assessment of kidneys from ED. PATIENTS AND METHODS A total of 84 ED aged > or = 60 yr were evaluated. In 19 cases, the kidneys were not used, mainly because of atherosclerotic vascular lesions. A histological score (HS) from 0 to 12 was awarded, considering the proportion of glomerulosclerosis, tubular atrophy, interstitial fibrosis, and arterial and arteriolar narrowing. On the basis of the HS, 37 donors were selected for 40 ST and 21 for DKT, three were discarded. All recipients received triple-drug therapy based on calcineurin inhibitors, mycophenolate mofetil and steroids. RESULTS Primary non-function was observed in three of 40 ST and one of 21 DKT. Acute tubular necrosis occurred in 22/40 ST and in 11/21 DKT. Acute rejection occurred in 16/40 ST and four of 21 DKT. Renal function was satisfactory in both groups, with 1-yr S-Cr = 171 micromol/L and 137 micromol/L, respectively in the ST and DKT groups. One-year patient survival was 92% in ST and 100% in DKT; 1-yr graft function was 87% in ST and 95% in DKT. CONCLUSION The histological assessment of kidneys from ED enables a correct selection of kidneys for ST or DKT and prevents the transplantation of high-risk kidneys.

Abstract
Elderly patients with end-stage organ failure are now more frequently undergoing transplantation. Medication management in this population is challenging because of the combination of multiple comorbidities, polypharmacy, and immunological, pharmacokinetic and pharmacodynamic changes attributable to the aging process. Immunosuppressive medications can exacerbate pre-existing medical conditions and promote the development of disease processes. Cardiovascular disorders, such as hypertension, coronary artery disease, congestive heart failure and arrhythmias are common in elderly transplant recipients, and account for most of the deaths in this population. Blood pressure, blood glucose and cholesterol control is of particular concern because elderly transplant recipients frequently have or develop these complications. Elderly transplant recipients are commonly receiving anticoagulation therapy with warfarin and are at a higher risk of bleeding, especially if they have renal dysfunction. Infectious complications occur frequently in the transplanted population, with pneumonia being the most common infection seen in hospitalised patients. Attention to vaccination for the prevention of influenza and pneumococcal infections is important because of the increased risk of these diseases in this population. Depression itself has been associated with decreased survival in older individuals, and depression in elderly transplant recipients may be reversible with the administration of pharmacological agents. Effective long-term care of transplant recipients demands an understanding of how particular medications affect clinical evaluation and treatment. This article addresses some of the practical issues surrounding medication management and prevention of these particular problems in elderly transplant recipients.

Abstract
OBJECTIVE To evaluate the surgical findings and outcome of locally allocated, blood-group-compatible but HLA-unmatched cadaveric kidneys in first renal transplantation of donor/recipient pairs aged 65 years and above (Eurotransplant Senior Program=ESP). METHODS 26 patients of the study group (donor age 70.4 +/- 3.6/recipient age 67.7 +/- 2.8) were compared to 30 controls aged 60 and above (mean recipient age 62.6 +/- 2.3/mean donor age 43.8 +/- 15.3). For controls kidney allocation included HLA matching. RESULTS Cold ischemic time (ESP vs. controls 501 vs. 883 min; p<0.05) and mean number of HLA mismatches (4.2 +/- 1.36 vs. 1.6 +/- 1.62; p<0.05) differed significantly. Delayed graft function was lower in the study group (12% vs. 43%; p<0.05), rejection episodes in the ESP group were numerous but did not differ significantly from the controls (46% vs. 30%; p=0.21). More intraoperative complications and a higher incidence of donor organ arteriosclerosis (p<0.05) were seen in the ESP group. Three-year graft survival uncensored and censored for death with functioning graft did not differ, even though mean creatinine and creatinine clearance differed significantly beginning at month three. Three-year patient survival (55% vs. 81%) differed in favour of the control group, even though the difference was not significant due to small number of patients. CONCLUSION "Old-for-old" kidney transplantation with local allocation yields graft survival rates comparable to HLA-matched young grafts and is a good approach to extend the donor and recipient pool. Careful patient selection is advised.

Abstract
The need to face the increasing gap between the supply and the demand of transplants has led to the development of a permanent network of trained medical staff responsible for the organ donation and removal process in all centers accredited for that process. In Spain, this activity received a specific budget, like any other medical activity in hospitals, and the responsible staff became accountable for performance. This system dramatically increased the number of potential donors referred, not only young donors with trauma, but also elderly donors dying from stroke. The effect was that the donation rate increased by more than 100% in 10 years (from 14 to 34 donors per million population). Consequently, so did all the transplant figures. In some areas, such as Catalonia, it has been demonstrated that sustained kidney transplant activity of over 60 procedures per million population can maintain or slightly decrease the waiting list, despite increasing incidence and prevalence of end-stage renal failure. Quality monitoring of the donation and retrieval process shows that there are still opportunities for improvement if all potential donors are referred and all technical problems are overcome. Living donation and nonheart beating organ retrieval should also be promoted.

Abstract
The terms extended donor or expanded donor mean changes in donor acceptability criteria. In almost all cases, the negative connotations of these terms cannot be justified. Factors considered to affect donor or organ acceptability have changed with time, after showing that they did not negatively affect graft or patient survival per se or when the adequate measures had been adopted. There is no age limit to be an organ donor. Kidney and liver transplantation from donors older than 65 years can have excellent graft and patient actuarial survival and graft function. Using these donors can be from an epidemiological point of view the most important factor to esablish the final number of cadaveric liver and kidney transplantations. Organs with broad structural parenchyma lesion with preserved functional reserve and organs with reversible functional impairment can be safely transplanted. Bacterial and fungal donor infection with the adequate antibiotic treatment of donor and/or recipient prevents infection in the latter. The organs, including the liver, from donors with infection by the hepatitis B and C viruses can be safely transplanted to recipients with infection by the same viruses, respectively. Poisoned donors and non-heart-beating donors, grafts from transplant recipients, reuse of grafts, domino transplant and splitting of one liver for two recipients can be an important and safe source of organs for transplantation.

Abstract
We performed 41 kidney transplants in patients >70 years (35 single and 6 dual), with a mean recipient age of 72+/-2 years, from January 1990 to December 2001. Mean age of the donors was 69+/-12 years. Immunosuppression used triple therapy with steroids, mycophenolate mofetil, and cyclosporine or tacrolimus. Cold ischemia time was 23+/-3 hours. The incidence of primary nonfunction was 4.8%, and delayed graft function 58.5%. Acute rejection incidence was 12%. The actuarial patient survival rates at 12, 24, and 36 months were 82.5%, 82.5%, and 75%, respectively. Actuarial survival rates of the grafts censuring for death of the recipient with a functioning graft were 89.5%, 86%, and 68%, respectively. Nine of the 18 graft losses were due to recipient death. Overall, renal transplant recipients >70 years showed good results. The principal cause of graft loss was recipient death.

Abstract
Pretransplantation biopsies of kidney grafts have become a key to select organs suitable for transplantation from marginal donors. The main microscopic features to be evaluated are as follows: percentage of glomerulosclerosis, interstitial fibrosis and vascular pathology. Although the percentage of glomerulosclerosis prognosticates kidney outcome, it has not yet been established what the age limit and type of kidney injury absolutely forbid the use of a particular organ. The principal reason for the controversy about the real value of the biopsy is due to the limited knowledge of the impact of age on the morphology of renal injuries. We reviewed 50 autopsies of patients older than 65 years, and 75 kidney biopsies showing renal disease. The percentage of glomerulosclerosis was always <15% in autopsy material, and <20% in kidney biopsies. We consider that improvement of the predictive value of pretransplantation renal biopsies may be achieved with the following guidelines: sufficient size of wedge biopsies (1.5 cm deep), not limited to the subcapsular area; never having <25 glomeruli; and a fast paraffin embedding technique that allows an objective evaluation of percentage of glomeruli and arterial-arteriolar damage. Transplantation is contraindicated when there is >20% of glomerulosclerosis accompanied by arteriolar damage.

Abstract
Shortage of kidney donor is still a major limitation for renal transplantation programs. This review focuses on the emerging practices, adopted to increase transplant activities, of expanding the criteria for donor and recipient selection without exposing the recipient to the drawbacks of a graft with inadequate nephron mass. Expanding the donor pool inevitably led to consideration for kidney transplantation of organs from older donors or from donors with hypertension, diabetes or other renal diseases. To fit the reduced performance of these suboptimal organs with the renal requirement of the recipient, selection of recipients with reduced metabolic requirements or increase of nephron mass by simultaneous transplantation of two suboptimal kidneys in the same recipient have been pursued. However, a critical aspect of both approaches is to quantify functioning nephron mass provided to the recipient by pre-transplant kidney biopsies. Morphological parameters assessed on kidney biopsies at the time of donor evaluation may serve to quantify the preserved tissue and to discriminate chronic irreversible lesions from acute changes that may account for a transiently impaired renal function in the donor, but that may recover after transplant.

Abstract
UNLABELLED On 4 January 1999, the Eurotransplant Senior Program (ESP) was implemented within the Eurotransplant kidney allocation scheme. PATIENTS AND METHODS Kidneys obtained from donors aged over 65 years of age (65+) were allocated to a selected group of nonimmunized 65+ patients undergoing their first transplant. All transplants were performed locally to minimize cold-ischemic time. All transplants performed with kidneys from elderly donors that were allocated via ESP (ESP group) were compared to transplants performed with similar kidneys allocated via the standard renal allocation system (control group). Initial kidney function and 1-year graft outcome were assessed. RESULTS In 1999, 227 ESP and 102 control transplants were performed. The duration of cold-ischemic time was 12 and 19 h for the ESP and control groups, respectively. No rejection episodes occurred in 60% and 67% of the ESP patients and controls, respectively, while a direct kidney function was observed in 59% of ESP and 49% of control patients. The 1-year graft survival rates, censoring for graft losses due to deaths in patients with functioning grafts, were 86% and 79%, respectively. CONCLUSION An old-for-old renal allocation algorithm can be successful provided that risk factors, such as cold-ischemic time, are reduced.

Abstract
The objective of this study was to evaluate estimated and measured donor renal function in predicting graft function long-term and to identify donor criteria associated with nonacceptable graft prognosis. In 200 consecutive cadaver donors creatinine clearance was measured at explantation and estimated using the Cockcroft formula on admission serum creatinine. Graft function was evaluated in recipients (n = 387) by 24-h creatinine clearance regularly during 3 years after transplantation. Measured creatinine clearance correlated to some extent with long-term graft function, while Cockcroft estimation was slightly superior and similar to using donor age only. Kidneys from donors with intra-operative creatinine clearance < or = 55 mL/min (median 50 mL/min) produced acceptable recipient graft function of 48 mL/min at 3 years and 76% 3-year graft survival. Donor age > or =60 years resulted in clearance at 3 years of 29 mL/min and 78% 3-year graft survival; adding the criteria of admission Cockcroft < or =60 mL/min, graft function at 3 years (28 mL/min) and 3-year graft survival (76%) were similar. In conclusion, creatinine-based estimates of the functional capacity of the donor kidney, calculated or intra-operatively measured, do little to improve the ability of donor age alone to predict long-term allograft function after renal transplantation, and nonacceptable donors are not discriminated.

Abstract
In parallel with increased clinical demand, less than optimal or so-called marginal kidney grafts are being used for transplantation. In addition to donor age, it appears that several factors may impact negatively on the quality of the graft. Most importantly, a more precise definition of the term 'marginal graft' is needed. The present review analyzes potential risk factors, suggests scoring systems for a more precise definition, and discusses potential treatment options to improve the quality of marginal grafts.

Abstract
BACKGROUND The horseshoe kidney is the most common anatomic renal variation, with an incidence of 1 in 600 to 800. It represents a fusion anomaly, usually of the lower poles. Horseshoe kidneys can be transplanted en bloc or after division of the renal isthmus. However, the great variation in origin, number, and size of renal arteries and veins leads to some reluctance to use horseshoe kidneys for transplantation. The aim of this study is to assess the results of horseshoe kidney transplantation. METHODS All data concerning horseshoe kidney transplantations within the Eurotransplant region were collected and were divided into en bloc and split transplantations. A matched control group was defined, and the three groups were analyzed with respect to the occurrence of primary nonfunction, graft survival, patient survival, and finally posttransplant serum creatinine values. RESULTS From 1983 to 2000, 8 horseshoe kidneys were transplanted en bloc and 26 were split and transplanted into 47 recipients. The results of these transplantations were compared with 110 transplantations in the control group. No significant differences among the three groups could be found, either in the short- or long-term posttransplant results. CONCLUSIONS The results of horseshoe kidney transplantation, either en bloc or split, are equal to the posttransplant results of kidneys with a normal anatomy. Bearing in mind the shortage of donors, horseshoe kidneys should certainly be used for transplantation.

Abstract
PURPOSE Horseshoe kidney is the most common anatomical renal variation. It represents a fusion anomaly, usually of the lower poles. Horseshoe kidneys can be transplanted en bloc or after division of the renal isthmus. We constructed a decision cascade for horseshoe kidney transplantation. MATERIALS AND METHODS A worldwide survey of transplantation clinics and foundations was performed to discover cases of horseshoe kidney transplantation. In each case data were collected on horseshoe kidney anatomy and post-transplantation results. The number of renal arteries and veins was correlated with primary nonfunction due to technical failure. RESULTS From 1975 to 2000, 23 horseshoe kidneys were transplanted en bloc, while 57 were split and transplanted into 97 recipients. Primary nonfunction was observed in 4.3% and 13.4% of en bloc and divided transplanted kidneys, respectively. Postoperatively a urinary fistula formed after renal isthmus division in 2 cases. An increased number of renal vessels was not associated with an increased risk of primary nonfunction. CONCLUSIONS Horseshoe kidney anatomy should be closely inspected after explantation. The decision to split a horseshoe kidney should be based on urinary collecting system anatomy in the renal isthmus and on the number as well as the position of the renal vessels. Horseshoe kidneys can and should always be considered for transplantation.

Abstract
Nowadays organ transplantations suffer from a lack of donors. Thus the waiting list of patients is constantly growing. Several ways to increase organ procurement are being evaluated. About 50% of cerebral deaths are related to vascular cerebral in patients older than 60 years. For the last few years, organs have been harvested from these patients despite their age. As the quality of the grafts is reduced, transplantation of one kidney may be insufficient whilst transplantation of the two kidneys to the same recipient is technically possible. We report here a case of a 44-year-old patient who was transplanted with two kidneys in September 2000. The donor was 85-year-old patient who died after prolonged cardiac arrest. Kidney biopsy showed a 16% rate of sclerotic glomeruli and mild interstitial fibrosis. The creatinine clearance estimated by the Cockcroft formula was 50 mL.min-1. The double kidney transplantation was successful, without any surgical or anaesthetic complication. Restoration of urine production was immediate. Three months after the transplantation, creatinine clearance was 80 mL.min-1. This observation gives the opportunity to discuss the criteria for organ harvesting in patients with cerebral death. Donor age should not remain anymore a systematic contra indication for kidney or liver donation. Renal function, macroscopic examination and histological findings seem more important for making a decision in taking the graft. Double transplantation, here the second case in France, has been performed for several years in other countries, and has permitted to expand the pool of donors, thus increasing the number of transplanted patients.
