BACKGROUND: A shortage of donors poses a serious problem for organ transplantation around the world. In response, the concept of the expanded criteria donor (ECD) has been defined to include donors with traditionally less favorable characteristics. That definition has now been accepted and is being applied in kidney transplantation in the United States and Europe. However, the ECD has not yet been defined for deceased donor kidney transplantation in Japan. PATIENTS AND METHODS: We analyzed data on graft survival and relevant risk factors in patients who received deceased donor kidney transplants through the East Japan Branch of the Japan Organ Transplant network (n = 1051)...

Despite many achievements in renal transplant in the past few years regarding immunosuppression and tissue matching, the rates of early and late graft loss and return to dialysis are still high. Many of those with primary graft failure will be listed for a kidney retransplant, as this allows for better quality of life than dialysis. Many challenges face those requiring renal retransplant, including first graft nephrectomy and whether site of retransplant should be ipsilateral or contralateral, whether to conduct preemptive retransplant or wait while on dialysis, additional immunologic factors, immunosuppression after retransplant, cancer risk, BK virus infection, and retransplant in pediatrics...

INTRODUCTION: Renal transplantation (RT) represents actually the most effective therapy in patients with end-stage renal failure as it is cost effective, allows for a normal life style and reduces the risk of mortality from dialysis related complications. The purpose of the present review is to update the recent published literature regarding the technical aspects, diagnosis and the urological complications associated with renal transplantation. EVIDENCE ACQUISITION: A comprehensive literature review was performed using PubMed and Thomson-Reuters Web of Science between February 2014 and June 2016...

Adenine phosphoribosyltransferase deficiency is a rare autosomal recessive disorder of uric acid metabolism that leads to formation and excretion of 2,8-dihydroxyadenine into urine. The low solubility of 2,8-dihydroxyadenine results in precipitation and formation of urinary crystals and renal stones. Patients with this disorder usually have recurrent nephrolithiasis and can develop nephropathy secondary to crystal precipitation in the renal parenchyma. The disease is most often underdiagnosed and can recur in renal transplant, causing graft failure...

BACKGROUND: Enteric hyperoxaluria (EH) occurs with a rate of 5-24% in patients with inflammatory bowel disease, ileal resection and modern bariatric surgery. The excessive absorption of calcium oxalate causes chronic kidney disease (CKD) in patients with EH. In the literature, a single experience was reported in combined intestine-kidney transplantation (CIKTx) in patients with CKD due to EH. METHODS: After a report of 2 successful cases of CIKTx in patients with EH and CKD, one was performed at our center in a 59-year-old Caucasian female who developed intestinal failure with total parenteral nutrition (TPN) dependence after a complication post-bariatric surgery...

BACKGROUND: Patients with high panel-reactive antibody (PRA) levels before transplantation tend to remain on the waiting list longer when considering cadaveric donor transplantation and have worse outcomes than those with lower PRA levels. This study investigated the impact of the pretransplantation PRA level on rejection and graft survival after kidney transplantation in patients with a negative crossmatch (CXM(-)) and no donor-specific antibody (DSA(-)). METHODS: We retrospectively analyzed 513 recipients of kidney allograft treated from January 2009 to April 2013...

BACKGROUND: Renal squamous cell carcinoma is a rare primary tumor of the kidney that rapidly invades local structures and has a poor prognosis. Presentation is usually nonspecific and is associated with renal stone disease and chronic infection. Immunosuppressed renal transplant recipients are more likely to develop a malignancy than the general population. Squamous cell carcinoma of the kidney in the context of a renal transplant and long-term immunosuppression has not previously been described in the literature...

PURPOSE: Partial nephrectomy is the accepted standard of care for treatment of patients with small renal masses. The primary goal while performing partial nephrectomy is cancer control with a secondary important goal of maximizing renal function preservation with minimal perioperative morbidity. Recent studies have highlighted the importance of renal parenchymal quality and quantity postoperatively rather than duration of ischemia in determining long-term renal function. We review the available data regarding perioperative renal function optimization with special interest in ischemia during partial nephrectomy, highlighting the controversies and establishing future lines of investigation...

Patients returning to dialysis after kidney transplant failure represent approximately 5%-15% of the population starting hemodialysis. These patients exhibit a high risk of morbidity and mortality attributed mainly to the exposure to immunosuppressive medications and to a uremic environment. The purpose of this paper was to review data regarding survival after renal allograft failure and the optimal management of patients before returning to dialysis. Moreover, issues surrounding nephrectomy after renal allograft failure, the tapering of immunosuppression and the possibility of retransplantation are examined, because they seem to be crucial for patient survival and the quality of life...

INTRODUCTION: Autosomal-dominant polycystic disease (ADPKD) represents 5%-10% of cases of end-stage renal failure. However, management of these patients in terms of whether or not to perform a transplant and optimal timing remains controversial. The objective of our analysis was to evaluate graft survival in patients with ADPKD in which we conduct pretransplant nephrectomy. METHODS: This retrospective study including renal transplant patients secondary to ADPKD in our hospital between January 2000 and December 2012...

Calcium oxalate (CaOx) crystal deposition is a common finding immediately after kidney transplantation. However, small depositions of CaOx could be benign while extensive depositions lead to poor graft outcome. Here we report three cases with end-stage renal disease (ESRD), bilateral nephrolithiasis, and unknown diagnosis of primary hyperoxaluria (PH) who underwent a renal transplant and experienced an early-onset graft failure. Although an acute rejection was suspected, renal allograft biopsies and subsequent allograft nephrectomies showed extensive CaOx deposition, which raised a suspicion of PH...

Transplant nephrectomy (TN) is associated with significant morbidity and mortality and influences the outcome of subsequent renal transplantation. The aim of this study was to identify the reasons for TN in a single transplant center in the United Kingdom and to determine the complication rate, effect on relisting and re-transplantation. We studied all the TNs in our center from January 2000 to December 2011. Detailed information including cause of allograft failure and reason for TN were analyzed. Of 602 renal transplants performed at our center during the period of the study, 42 TNs were performed on 38 (6%) patients (24 men and 14 women)...

Sensitization following renal allograft failure (AF) is highly variable. Some patients remain non-sensitized (NS), while others become highly sensitized (HS). We studied 66 NS patients who experienced AF after initial kidney transplantation. Post-failure, two main groups of NS panel reactive antibody (PRA) class I and II <10% and HS patients (PRA class I or II ≥80%) were identified. The impact of acute rejection (AR), immunosuppression withdrawal (ISW) at AF, allograft nephrectomy, graft intolerance syndrome (GIS), and both standard serologic and eplet-based mismatches (MM) in inducing HS status after failure was examined...

INTRODUCTION: Shortage of deceased donor kidneys has resulted in an increased rate of kidney transplantation from living unrelated donors (LURDs). However, there are concerns about short-term and long-term morbidity of the donors. This study reports the clinical and biochemical factors in a follow-up program of Iranian LURDs, one of the largest reported series of kidney donors. MATERIALS AND METHODS: Of 7500 individuals who underwent living donor nephrectomies between 2005 and 2008, a total of 1549 participated in this study...

OBJECTIVE AND METHOD: To focus on indications and results of ablative treatments (cyoablation, radiofrequency) for small renal masses, a bibliographic research was conducted in MedLine database using terms of "ablative treatment", "cryotherapy", "radiofrequency", "kidney cancer", "renal cell carcinoma". Sixty-four articles were selected. RESULTS: Carcinologic outcomes seem to be better with cryoablation than with radiofrequency. Available results have to be balanced according to surgical approach, teams' experience and duration of follow-up...

HLA antibodies can damage a kidney transplant. In January 2013, consensus guidelines from The Transplantation Society were published regarding technical aspects of HLA antibody determination, as well as their potential significance in the pre- and posttransplantation periods. During the past 2 years, new studies have been reported, but controversies remain. In this article, these new data related to HLA antibodies in kidney transplantation are reviewed and compared to relevant prior research. Pretransplantation sensitization issues are discussed, including the new more sensitive assays (flow cytometry and solid-phase immunoassays such as Luminex single-antigen bead assays)...
