Abstract
INTRODUCTION Broader use of donation after circulatory death (DCD) and nonconventional grafts for liver transplant helps reduce disparities in organ availability. Limited data, however, exists on outcomes specific to nonconventional graft utilization in older patients. As such, this study aimed to investigate outcomes specific to conventional and nonconventional graft utilization in recipients > 70 y of age. METHODS 1-to-3 matching based on recipient sex, Model for End-Stage Liver Disease score, and donor type was performed on patients ≥70 and <70 y of age who underwent liver transplant alone at Mayo Clinic Arizona between 2015 and 2020. Primary outcomes were posttransplant patient and liver allograft survival for recipients greater than or less than 70 y of age. Secondary outcomes included grafts utilization patterns, hospital length of stay, need for reoperation, biliary complications and disposition at time of hospital discharge. RESULTS In this cohort, 36.1% of grafts came from DCD donors, 17.4% were postcross clamp offers, and 20.8% were nationally allocated. Median recipient ages were 59 and 71 y (P < 0.01). Recipients had similar Intensive care unit (P = 0.82) and hospital (P = 0.14) lengths of stay, and there were no differences in patient (P = 0.68) or graft (P = 0.38) survival. When comparing donation after brain death and DCD grafts in those >70 y, there were no differences in patient (P = 0.89) or graft (P = 0.71) survival. CONCLUSIONS Excellent outcomes can be achieved in older recipients, even with use of nonconventional grafts. Expanded use of nonconventional grafts can help facilitate transplant opportunities in older patients.

Abstract
The practice of dual kidney transplantation (DKT) from adult marginal deceased donors (MDDs) dates back to the mid-1990s with initial pioneering experiences reported by the Stanford and Maryland groups, at which time the primary indication was estimated insufficient nephron mass from older donors. Multiple subsequent studies of short and long-term success have been reported focusing on three major aspects of DKT: Identifying appropriate selection criteria and developing scoring systems based on pre- and post-donation factors; refining technical aspects; and analyzing mid-term outcomes. The number of adult DKTs performed in the United States has declined in the past decade and only about 60 are performed annually. For adult deceased donor kidneys meeting double allocation criteria, >60% are ultimately not transplanted. Deceased donors with limited renal functional capacity represent a large proportion of potential kidneys doomed to either discard or non-recovery. However, DKT may reduce organ discard and optimize the use of kidneys from MDDs. In an attempt to promote utilization of MDD kidneys, the United Network for Organ Sharing introduced new allocation guidelines pursuant to DKT in 2019. The purpose of this review is to chronicle the history of DKT and identify opportunities to improve utilization of MDD kidneys through DKT. This article is protected by copyright.

Abstract
INTRODUCTION Kidney transplantation is championed as the gold standard treatment for patients with end-stage kidney disease. According to the biomedical agency, there is an increasing number of patients waiting for kidney transplantation. Faced with organ shortage, the use of marginal grafts may well increase the number of available kidney grafts. Occasionally, during dual kidney graft transplantation, the poor quality of one of the two grafts, or other specific circumstances, may lead to transplantation of only one of the two grafts. We have compared patient outcome concerning single kidney transplantation from an initial dual kidney graft with respect to dual kidney graft transplantation. MATERIAL Among 67 patients enrolled for a dual kidney graft, 39 dual kidney grafts (group 1) were compared with 12 grafts performed with only one of the two kidneys of a dual kidney graft (group 2) as well as 15 grafts performed following a classic kidney graft protocol (group 3). RESULTS The survival of grafts was respectively for groups 1, 2 and 3 of 100%, 72,5% and 75,4% (P=0.17). The survival of patients was respectively for groups 1, 2 and 3 of 78.3%, 89.9% and 87.8% (P=0.47). CONCLUSION Our study suggests that transplantation of a single kidney, initially proposed as dual kidney graft candidate, has satisfying results in terms of graft survival and patient mortality at the expense of poorer renal function in comparison to dual kidney graft. Indeed, there was no significant difference in the survival of patients and grafts. This seems promising taking into consideration that the aim of transplantation in elderly recipients is primarily to avoid dialysis, rather than having optimal post-transplantation kidney function.

Abstract
OBJECTIVE To discuss a novel technique of dual kidney transplantation that has not been described in literature. METHODS Dual Kidney Transplantation (DKT) is done for kidneys from expanded criteria donors. The 3 described techniques in literature (bilateral placement, unilateral placement with separate or patch anastomosis) have some disadvantages. This newer technique describes the use of the donor iliac artery as an interposition Y graft for joining both kidneys of the dual kidney transplant. This method can overcome some of the disadvantages associated with the previously described techniques. The ureters were implanted in urinary bladder separately in one recipient and together in another recipient. RESULTS This technique was used in 2 cases. The cold ischemia time was 275 minutes and 765 minutes, respectively while the operative time was 187 minutes and 192 minutes, respectively in the 2 patients. The first patient has creatinine of 0.83 mg/dl on last follow up at 6 months whereas the other patient has creatinine of 1.12 mg/dl at 3 months follow up. Computed tomography angiography of both the patients revealed good contrast uptake in both kidneys with no stenosis, torsion or lymphocele. CONCLUSION The newer technique avoids scarring of both iliac fossa in DKT while reducing operative time and secondary warm ischemia time by doing a single arterial anastomosis in the recipient and allows easier placement of both kidneys in the right iliac fossa.

Abstract
Kidney transplantation (KT) is one of the treatment options for patients with chronic kidney disease. The number of patients waiting for kidney transplantation is growing day by day. Various strategies have been put in place to expand the donor pool. Extended criteria donors are now accepted more frequently. Increasing number of elderly donors with age > 60 years, history of diabetes or hypertension, and clinical proteinuria are accepted as donor. Dual kidney transplantation (DKT) is also more frequently done and experience with this technique is slowly building up. DKT not only helps to reduce the number of patients on waiting list but also limits unnecessary discard of viable organs. Surgical complications of DKT are comparable to single kidney transplantation (SKT). Patient and graft survivals are also promising. This review article provides a summary of evidence available in the literature.

Abstract
BACKGROUND Dual kidney transplantation (DKT) was developed to improve outcomes from transplantation of extended criteria donors (ECD). This study examined which surgical techniques have been reported for DKT and whether any technique had superior patient and graft survival. METHOD Electronic databases were searched for published studies mapping to MESH terms: "kidney or renal" AND "transplan*" AND "dual or double." Single case reports, studies of patients less than 18 years old, studies which did not describe the surgical technique, and studies that did not report patient or graft survival were excluded. RESULTS Fifteen reports of 434 DKT recipients were identified. Three techniques were described: bilateral placement; unilateral placement with separate anastomoses; and unilateral placement with patch anastomoses. Patient survival across all three techniques was over 95% at 1 year, and graft survival was also similar at over 90%. Rates of delayed graft function were between 20% and 30% across all techniques. CONCLUSION The three techniques have equivalent delayed graft function as well as patient and graft survival rates. This is an encouraging result as it means that the surgeon can choose to use the technique which is most appropriate for their own skills and for the patient.

Abstract
AIM A major problem for the transplant society is a shortage of organs for transplantation compared with the number of patients on the waiting list. This study aimed to assess the results of the transplantation of kidneys procured from older donors. PATIENTS AND METHODS A total of 27 kidneys procured from donors age 70 years or older were transplanted between January 1, 2010, and April 25, 2015. These represented only 4.1% of the 657 kidneys transplanted from deceased donors during this period at the same center. RESULTS Delayed graft function (DGF) in the recipients of kidneys procured from donors age 70 or older occurred in 46.1% of patients, whereas the recipients of kidneys from younger donors showed DGF at a frequency of 32.7% (P = NS). The annual and 3-year survival rates of kidneys in the study group were 85% and 80%, respectively, and in the control group were 92.5% and 88.6%, respectively (P = NS). According to the Polish National Organ Procurement Organization (Poltransplant), the annual survival rate of a transplanted kidney in Poland stands at 89%, whereas the 3-year survival rate is 82%. We detected no significant posttransplantation differences in the serum creatinine concentration and in the estimated glomerular filtration rate between the study and control groups. The donor age and donor creatinine were the variables independently associated with DGF. CONCLUSIONS The results of transplantation of kidneys from elderly donors were comparable to those of transplantation from younger donors. Kidneys harvested from elderly donors should be used for a transplant after a preliminary assessment.

Abstract
The disparity between the number of available renal donors and the number of patients on the transplant waiting list has prompted the use of expanded-criteria-donor (ECD) renal allografts to expand the donor pool. ECD allografts have shown good results in appropriately selected recipients, yet a number of renal allografts are still discarded. The use of dual renal transplantation may lower the discard rate. Additionally, the use of perfusion systems may improve acute tubular necrosis rates with these allografts. We report a successful case of a dual transplant with ECD allografts using a perfusion system. The biopsy appearance and the pump characteristics were suboptimal for these kidneys, making them unsuitable for single transplantation; however, the pair of transplanted kidneys provided increased nephron mass and functioned well. We recommend that ECD kidneys that are individually nontransplantable be evaluated for potential dual renal transplantation. Biopsy criteria and perfusion data guidelines must be developed to improve the success rates with ECD dual renal allografts. Finally, recipient selection is of utmost importance.

Abstract
One option for using organs from donors with a suboptimal nephron mass, e.g. expanded criteria donors (ECD) kidneys, is dual kidney transplantation (DKT). In adult recipients, DKT can be carried out by several techniques, but the unilateral placement of both kidneys (UDKT) offers the advantages of single surgical access and shorter operating time. One hundred UDKT were performed using kidneys from ECD donors with a mean age of 72 years (Group 1). The technique consists of transplanting both kidneys extraperitoneally in the same iliac fossa. The results were compared with a cohort of single kidney transplants (SKT) performed with the same selection criteria in the same study period (Group 2, n = 73). Ninety-five percent of UDKTs were positioned in the right iliac fossa, lengthening the right renal vein with an inferior vena cava patch. In 69% of cases, all anastomoses were to the external iliac vessels end-to-side. Surgical complications were comparable in both groups. At 3-year follow-up, patient and graft survival rates were 95.6 and 90.9% in Group 1, respectively. UDKT can be carried out with comparable surgical complication rates as SKT, leaving the contralateral iliac fossa untouched and giving elderly recipients a better chance of receiving a transplant, with optimal results up to 3-years follow-up.

Abstract
It has been suggested that dual kidney transplantation (DKT) improves outcomes for expanded criteria donor (ECD) kidneys. However, no criteria for allocation to single or dual transplantation have been assessed prospectively. The strategy of DKT remains underused and potentially eligible kidneys are frequently discarded. We prospectively compared 81 DKT and 70 single kidney transplant (SKT) receiving grafts from ECD donors aged >65 years, allocated according to donor estimated glomerular filtration rate (eGFR): DKT if eGFR between 30 and 60 mL/min, SKT if eGFR greater than 60 mL/min. Patient and graft survival were similar in the two groups. In the DKT group, 13/81 patients lost one of their two kidneys due to hemorrhage, arterial or venous thrombosis. Mean eGFR at month 12 was similar in the DKT and SKT groups (47.8 mL/min and 46.4 mL/min, respectively). Simulated allocation of kidneys according to criteria based on day 0 donor parameters such as those described by Remuzzi et al., Andres et al. and UNOS, did not indicate an improvement in 12-month eGFR compared to our allocation based on donor eGFR.

Abstract
PURPOSE The critical shortage of kidneys available for transplantation has led to alternate strategies to expand the pool. Transplantation of the 2 kidneys into a single recipient using organs suboptimal for single kidney transplantation was suggested. We assessed results in 24 grafts allocated for dual kidney transplantation vs those in a control group of 44 designated for single kidney transplantation. Each group underwent pretransplant biopsy and recipients were age matched. MATERIALS AND METHODS Dual kidney transplantation was done in 24 of 1,091 transplants (2.1%) from 2001 to 2008. In patients with dual kidney transplant vs single kidney transplant mean recipient age was 60.6 vs 60.8 years, mean HLA-A, B and DR mismatches were 3.3 vs 2.9, and average patient waiting time was 15.6 vs 13.9 months. All grafts were perfused with University of Wisconsin solution with a mean cold ischemia time of 17.9 hours. On donor dual kidney biopsy in the dual kidney transplant vs single kidney transplant group the average fibrosis rate was 30% (range 25% to 45%) vs 25% (range 3% to 40%) and the glomerulosclerosis rate was 17.9% (range 3.2% to 40.7%) vs 7.1% (range 0% to 50%). RESULTS Good postoperative renal function was noted in 14 dual kidney transplantation cases. Acute tubular necrosis requiring dialysis developed in 5 patients as well as acute rejection in 1. Two dual kidney recipients (8%) died in the postoperative period with no single kidney deaths. One patient underwent bilateral transplantectomy. Mean anesthesia time was longer in the dual group (371 vs 212 minutes). Patient and graft survival was equivalent to that in the control group at 36 months. CONCLUSIONS Careful selection of marginal kidneys based on clinical and histological criteria allows the use of organs that would not ordinarily be sufficient for transplantation with acceptable outcomes. This is a valid strategy to address the organ shortage.

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
BACKGROUND Dual kidney transplantation (DKT) offers a safe way to face the organ shortage with good short-term and medium-term renal function. However, its application is limited by the longer operating time and the risk of surgical complication. This study reviews our results with DKT performed with an ipsilateral technique in terms of graft loss, graft and patient survival rates, and surgical complications. PATIENTS AND METHODS From January 2002 to March 2006, 23 patients underwent DKT through a monolateral Gibson incision with placement of both kidneys. RESULTS One primary nonfunction occurred (4%). Delayed graft function was observed in 3 DKT (13.3%). Acute rejection rate was 4.3% (1 patient). All patients are alive at a mean follow-up of 28 months. One-year and 2-year graft survival rates were 100% and 96%, respectively. Mean serum creatinine level at 1-year posttransplantation was 1.3 mg/dL (range, 0.8-2.1 mg/dL). One DKG recipient lost 1 graft, retaining the second normal functioning graft due to ureteral necrosis. The mean hospital stay after transplantation was 15 days (range, 12-34 days). CONCLUSIONS Monolateral placement in DKT offers the advantage of a single incision, minimizing the surgical risk. Tailored immunosuppression and careful selection of potential recipients, by excluding those with severe cardiopulmonary pathologies, could significantly improve both patient and graft survival in this group of patients.

Abstract
Dual kidney transplantation (DKT) from marginal donors is increasingly used at many centers to help cope with the organ shortage problem. The disadvantages of DKT consist in longer operating times and the risk of surgical complications. DKT can be performed in two ways, i.e. using monolateral or bilateral procedures. From October 1999 to June 2005, 58 DKTs were performed at our unit. In 29 cases (group I), the kidneys were extraperitoneally placed bilaterally in the iliac fossae via two separate incisions; as of June 2003, monolateral kidney placement was preferred in 29 cases, whenever compatible with the recipient's morphological status (group II). After a mean follow-up of 51 +/- 19 months for group I and 15 +/- 7 months for group II, all patients are alive with 1-year graft survival rates of 93% and 96%, respectively. Mean operating times were 351 +/- 76 min in group I and 261 +/- 31 min in group II (P = 0.0001). The mean S-creatinine levels in groups I and II were 132 +/- 47 and 119 +/- 36 mumol/l, respectively, at 1 year. We observed eight surgical complications in group I and seven in group II. Both techniques proved safe, with no differences in surgical complication rates. The monolateral procedure has the advantage of a shorter operating time and the contralateral iliac fossa remains available for further retransplantation procedures.

Abstract
Hypertension (HTN) and chronic kidney disease are highly prevalent diseases that tend to occur more frequently among disadvantaged populations, in whom prenatal care also tends to be poor. More and more evidence is emerging highlighting the important role of fetal programming in the development of adult disease, suggesting a possible common pathophysiologic denominator in the development of these disorders. Epidemiologic evidence accumulated over the past 2 decades has demonstrated an association between low birth weight and subsequent adult HTN, diabetes, and cardiovascular disease. More recently, a similar association has been found with chronic kidney disease. Animal studies and indirect evidence from human studies support the hypothesis that low birth weight, as a marker of adverse intrauterine circumstances, is associated with a congenital deficit in nephron number. The precise mechanism of the reduction in nephron number has not been established, but several hypotheses have been put forward, including changes in DNA methylation, increased apoptosis in the developing kidney, alterations in renal renin-angiotensin system activity, and increased fetal glucocorticoid exposure. A reduction in nephron number is associated with compensatory glomerular hypertrophy and an increased susceptibility to renal disease progression. HTN in low birth weight individuals also appears to be mediated in part through a reduction in nephron number. Increased awareness of the implications of low birth weight and inadequate prenatal care should lead to public health policies that may have long-term benefits in curbing the epidemics of HTN, diabetes, and kidney disease in generations to come.

Abstract
Expanded criteria donor (ECD) kidneys are transplantable deceased donor (DD) kidneys for which the average patient, graft survival, and renal function are inferior when compared to standard criteria DD kidneys. Although the term ECD kidneys has been used since the early 1990s to describe kidneys with various characteristics associated with poorer outcomes, the concept has been formally implemented in U.S. organ allocation. A DD kidney is considered to be an ECD organ if the estimated adjusted risk of graft failure is > or = 70% (RR > or = 1.70) compared to DD kidneys with standard characteristics of transplant suitability. The donor characteristics that define an ECD kidney include age > or = 60 years, or age 50-59 years plus two of the following: cerebrovascular accident as the cause of death, preexisting hypertension, or terminal serum creatinine greater than 1.5 mg/dl. In the aggregate, recipients of ECD kidneys have improved survival compared to end-stage renal disease (ESRD) patients on the kidney transplant waiting list. Patient survival is 5% lower at 1 year and 8-12% lower at 3-5 years for ECD kidney recipients. Adjusted graft survival in ECD kidneys is 8% lower at 1 year and 15-20% lower at 3-5 years after transplantation compared to standard criteria donor kidneys. However, patients less than 40 years of age, African Americans, Asians for whom the median waiting time is less than 1350 days receive no survival benefit from ECD kidney transplantation. Informed choice by the potential recipient is a prominent feature of the allocation policy regarding ECD kidneys. Since there are recipient characteristics associated with no survival benefit following ECD transplantation, nephrologists who refer patients for kidney transplantation should be familiar with the combination of donor and recipient factors that are likely to yield detrimental results.

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 Donor glomerulosclerosis, interstitial fibrosis, and fibrous intimal thickening correlate with graft outcome. We evaluate chronic lesions in donor biopsies according to Banff criteria and with a morphometric technique to ascertain their predictive value on graft outcome. METHODS We evaluated 77 cadaveric donor biopsies according to Banff criteria. Glomerulosclerosis was expressed as the percentage of global sclerotic glomeruli. The following morphometric parameters were obtained: cortical interstitial volume fraction (Vvint/c), cortical glomerular volume fraction (Vvglom/c), mean glomerular volume (Vg), mean and maximal intimal arterial volume fraction (Vvintima/art), and Vvintima/art of the largest artery. We evaluated the correlation of histologic lesions with delayed graft function, 3 months' glomerular filtration rate (GFR), and death-censored graft survival. RESULTS Multivariate logistic regression showed that delayed graft function was associated with cv score [relative risk (RR) 4.2 and 95% CI 1.1 to 16.0) and glomerulosclerosis (RR 1.06 and 95% CI 1.01 to 1.13). Stepwise regression showed that Vvint/c and glomerulosclerosis were independent predictors of 3 months' GFR (R= 0.62, P= 0.0001). Repeated analysis not considering morphometric parameters showed that glomerulosclerosis, cv score and ci score were independent predictors of 3 months' GFR (R= 0.64, P= 0.0001). A donor chronic damage score was generated considering glomerulosclerosis, cv score and ci score. This score after adjusting for clinical variables was associated with 3 months' GFR (R= 0.71, P < 0.0001) and death-censored graft survival (RR 2.2 and 95% CI 1.3 to 3.7). CONCLUSION Combined evaluation of donor glomerulosclerosis, chronic vascular and interstitial damage according to Banff criteria allows a precise prediction of graft outcome. Morphometric evaluation of donor biopsies does not improve the predictive value of semiquantitative grading.

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
OBJECTIVE To compare outcomes in recipients of expanded criteria donor (ECD) versus standard criteria donor (SCD) kidneys at a single center using a standardized approach with similar immunosuppression. SUMMARY BACKGROUND DATA Expanded criteria deceased organ donors (ECD) are a source of kidneys that permit more patients to benefit from transplantation. ECD is defined as all deceased donors older than 60 years and donors older than 50 years with 2 of the following: hypertension, stroke as the cause of death, or pre-retrieval serum creatinine (SCr) greater than 1.5 mg/dl. METHODS We retrospectively studied 90 recipients of adult deceased donor kidneys transplanted from October 1, 2001 to February 17, 2003, including 37 (41%) from ECDs and 53 (59%) from SCDs. ECD kidneys were used by matching estimated renal functional mass to recipient need, including the use of dual kidney transplants (n = 7). ECD kidney recipients were further selected on the basis of older age, HLA-matching, low allosensitization, and low body mass index. All patients received a similar immunosuppressive regimen. Minimum follow up was 9 months. RESULTS There were significant differences in donor and recipient characteristics between ECD and SCD transplants. Patient (99%) and kidney graft survival (88%) rates and morbidity were similar between the 2 groups, with a mean follow-up of 16 months. Initial graft function and the mean 1-week and 1-, 3-, 6-, 12-, and 18-month SCr levels were similar among groups. CONCLUSIONS The use of ECD kidneys at our center effectively doubled our transplant volume within 1 year. A systematic approach to ECD kidneys based on nephron mass matching and nephron sparing measures may provide optimal utilization with short-term outcomes and renal function comparable to SCD kidneys.

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
BACKGROUND Dual-kidney transplantation, where two usually aged adult kidneys are placed into an adult recipient, is one way to help alleviate the continuing disparity between the number of patients on the kidney transplant waiting list and those who receive kidney transplants each year. The Dual Kidney Registry was developed to analyze donor and recipient data and outcomes at several centers. METHODS Two hundred eighty-seven patients who have undergone transplantation since 1994 have been entered into the relational database. The patients were followed yearly after initial entry into the database. RESULTS The mean donor age was 58+/-13 years and the mean terminal creatinine clearance was 77+/-40 mL/min. The mean glomerular sclerosis on procurement biopsy was 16+/-13%. Delayed graft function (DGF), defined as dialysis in the first 7 days after transplantation, was a predictor of poor outcome, and increased cold storage time was a predictor of DGF. The overall incidence of DGF was 27%. In recipients with prompt graft function (PGF), the mean cold storage time was 22+/-9 hr versus 29+/-10 hr in recipients with DGF (P<0.001). The overall 1- and 5-year graft survival was 86% and 69%, respectively. The 1- and 5-year graft survival rates were significantly better in recipients with PGF (90% and 74%) versus DGF (79% and 54%) (P<0.002). CONCLUSIONS Cold storage time and DGF have a significant impact on the 1- and 5-year graft survival in recipients of dual-kidney transplants. The 5-year graft survival in recipients of dual-kidney transplants is excellent.

Abstract
BACKGROUND Organ shortage increasingly forces surgeons to consider the use of marginal organs. METHODS The authors report a case in which a kidney with traumatic dissection of the renal artery and marginal perfusion by means of collaterals was successfully transplanted into a 63-year-old patient. A computed tomographic scan of the donor showed a marginally perfused left kidney, suggestive of renal artery dissection. After surgical reconstruction of the renal artery, transplantation followed the usual course. RESULTS The organ started clearing shortly after the operation and was homogeneously perfused in a postoperative scan. Creatinine and blood urea nitrogen levels dropped to normal values within a couple of days after the transplantation. During 1 year of follow-up, organ function was always excellent and retention parameters were within the normal range. CONCLUSIONS This case illustrates that marginally perfused kidneys can be successfully used for transplantation in certain cases.

Abstract
The current organ shortage has led to the utilization of double kidney transplants from marginal adult donors, but outcomes data are limited. The United Network for Organ Sharing registry database was used to compare the outcomes of 403 dual adult kidney transplantations (DKT) and 11,033 single kidney transplantations (SKT) from 1997 to 2000. Graft and patient survival and the effect of multiple risk factors were evaluated. It was found that DKT patients were older, less sensitized, and received grafts from older, more mismatched donors with longer cold ischemia times. There was also a greater percentage of donors with a history of diabetes or hypertension and African-American recipients and donors in the DKT group. Graft survival was inferior in the DKT group, with a 7% lower graft survival rate at 1 yr. There was a higher incidence of primary nonfunction in the DKT group, although the incidence of delayed graft function, early rejection treatment, and graft thrombosis did not differ. Multivariate analysis was used to identify African-American recipient ethnicity and retransplant as risk factors for graft loss. Graft survival was comparable in DKT and SKT with donors over 55 yr of age. DKT resulted in inferior graft outcomes compared with SKT. When compared with SKT with donors over 55 yr of age, DKT resulted in similar graft outcomes. These otherwise discarded kidneys should be cautiously considered as a source of marginal donors.

Abstract
More frequently there is the need for renal transplantation of older patients. Against the background of an increasing number of old donors and recipients, Eurotransplant Leiden started the Eurotransplant Senior Program (ESP) 'old for old' in 1999. The ESP works with donors and recipients both over 65 yr. The kidneys are transplanted with short cold ischaemia time regardless of the human leukocyte antigen (HLA) compatibility. Compatibility of blood groups, negative crossmatch and less than 5% cytotoxic antibodies are required. First experiences from 10 patients at Heinrich Heine University hospital are reported here. The course of 10 transplanted patients is described from January 1999 until November 1999 (28.4+/-15.8 wk). Age of donor and recipient, cause of dialysis and concomitant diseases from recipients, function of the transplanted kidney and complications are analysed. Immunosuppression consisted initially of cyclosporin A, mycophenolic acid and steroids. The results of these 10 patients were compared to 14 patients who were transplanted according to the ordinary Eurotransplant criteria (Eurotransplant Kidney Allocation System) in the same period of time. Kidneys from six donors (70.5+/-3.3 yr) were transplanted to 10 different recipients (66.9+/-2.2 yr). The control group consisted of 14 patients (47.6+/-14.4 yr) who received kidneys from 14 donors (48.3+/-10.1 yr). One double kidney transplantation was performed in the senior group, i.e. two kidneys from a marginal donor were transplanted to one recipient ('two in one'). In the ESP group, cold ischaemia time was reduced by 5 h and mean of HLA mismatches was more than doubled. Mean length of hospitalisation of ESP and control groups was 47.2+/-28.2 and 34.2+/-11.6 d, respectively. Intraoperatively, no complications were seen, post-operative care was performed on a normal ward. ESP patients suffered more often from delayed graft function, which led to further need for haemodialysis for 11.2 d. Finally, 9 of 10 patients acquired a satisfactory renal graft function. A total of 13 biopsies were performed in eight cases. Altogether seven acute rejections in 6 patients were found (four interstitial, one vascular, one interstitial+vascular, one clinical). The 9 patients with sufficient renal graft function were discharged with a mean serum creatinine level of 2.3+/-0.5 mg/dL (control: 1.9+/-0.8 mg/dL). Comparing these 10 recipients to a control group consisting of 14 patients, the results are comparable and encouraging. In conclusion, the short-term results of the ESP are promising. Nevertheless, the post-operative care requires more attention due to several complications. Though the HLA compatibility was not considered, all rejections were coped with effectively. Quality of life was improved.

Abstract
BACKGROUND The increased utilization of expanded criteria kidney donors has necessitated the reevaluation of multiple donor risk factors to insure the best outcome from this valuable resource. Reports of decreased graft survival in recipients of kidneys from donors with > or =20% glomerular sclerosis (GS) have led many transplant centers to refuse these donor kidneys. The purpose of this study is to compare outcome in recipients of cadaveric donor kidneys with > or =20% GS versus those with <20% or no GS at our center. METHODS We retrospectively reviewed 18 donor and 19 recipient and outcome variables in 89 recipients of kidneys, which were biopsied at the time of transplantation, between February 1995 and November 1998. We evaluated outcome based upon the percent of GS and the degree of vasculopathy. RESULTS Donors with > or =20% GS were older and had more hypertension. Recipients of kidneys with > or =20% GS were older, had higher serum creatinine values at 1 and 2 years, but similar rates of delayed graft function and 2-year graft survival. Vasculopathy did not correlate to any important donor criteria except the percent GS. However, serum creatinine was significantly higher in recipients of kidneys with moderate vasculopathy versus none, up to 2 years after transplantation. There was no significant difference in graft loss based upon vasculopathy. CONCLUSION Kidneys from donors with > or =20% GS provide excellent outcome similar to kidneys from donors with no GS.

Abstract
A 58-year-old man underwent dual kidney transplantation. He was unable to move his right leg after surgery. This was caused by extensive lumbosacral plexopathy on the side of surgery. Lumbosacral plexopathy after kidney transplantation is uncommon, because the plexus has rich anastomotic blood supply, and ischemic injury is unlikely. However, isolated femoral neuropathy after renal transplantation has been reported, as the distal portion of this nerve is supplied by branches of internal iliac artery only and is more prone to ischemic injury during surgery. Dual-kidney transplantation involves a larger dissection, and the procedure takes 60 to 90 minutes longer than single-kidney transplantation. It involves more vascular reconstruction. This may predispose the lumbosacral plexus to ischemic injury. To the best of our knowledge, this is the first reported case of lumbosacral plexopathy after a dual kidney transplantation, and this may be seen more frequently because this procedure is becoming more common.

Abstract
There is a growing disparity between the demand for and the supply of kidneys for transplantation. The demographics of the donor pool are also changing. The average potential cadaveric organ donor is now more likely to be older, at greater risk for co-morbid conditions such as hypertension or viral infections, and more likely to die from cerebrovascular disease. These factors have led to an expansion of the criteria that defines the suitable organ donor. Expanded criteria donors are defined as the following: (1) at the upper and lower extremes in age; (2) having a history of hypertension or diabetes; (3) hemodynamically unstable; (4) non-heartbeating (cardiopulmonary death rather than brain death); (5) seropositive for hepatitis B or C; (6) having systemic infections; (7) having displayed high-risk social behavior for HIV infection; (8) having a history of malignancy; (9) having abnormal organ function; or (10) with renal anatomic anomalies or injuries. Use of kidneys from these "expanded criteria donors" is a two-edged sword. While they provide more organs for transplantation, the risk of suboptimal recipient outcome is increased. A rational approach to the use of each of these types of kidneys and proper selection of recipients is essential to obtain acceptable results. The article reviews the factors that have contributed to the successful transplantation of kidneys procured from expanded criteria organ donors and how these organs can be allocated most efficaciously to the appropriate recipients.

Abstract
BACKGROUND A novel but controversial method to increase the utilization of aged donor kidneys is the transplantation of both kidneys as a dual transplant. Initial single-center reports demonstrated outcomes similar to single kidneys from younger donors. In this report, we compare outcome in recipients of kidneys from donors > or =54 years of age who received a single kidney transplant reported to the United Network for Organ Sharing Scientific Registry versus a dual kidney transplant reported to the Dual Kidney Registry. METHODS A retrospective analysis was performed, comparing four donor and nine recipient and outcome variables between recipients of a single versus a dual transplant between March 1993 and March 1999. RESULTS Dual versus single transplants from donors > or =54 years of age have a significantly decreased incidence of delayed graft function, and lower serum creatinines up to 2 years after transplant despite having kidneys from significantly older donors with poorer HLA matching. CONCLUSIONS Dual kidney transplants improve graft performance and outcome in recipients of kidneys from donors > or =54 years of age.
