Renal lymphoma is an uncommon renal tumor in children. Unlike renal lymphomas presenting as bilateral disease and renal failure, we report a boy who presented with unilateral renal involvement. After initial nephrectomy, he achieved remission with multiagent chemotherapy but relapsed systemically within 3 months. He was initiated on salvage chemotherapy with autologous bone marrow transplant. Even though the initial manifestation was localized lymphoma eventually, it turned out to be a systemic disease. He succumbed to disease at 14 months from diagnosis...

Hyperphosphatemia and vascular calcification are frequent complications of chronic renal failure and bone morphogenetic protein 7 (BMP7) has been shown to protect against development of vascular calcification in uremia. The present investigation examined the potential reversibility of established uremic vascular calcification by treatment of uremic rats with BMP7. A control model of isogenic transplantation of a calcified aorta from uremic rats into healthy littermates examined whether normalization of the uremic environment reversed vascular calcification...

OBJECTIVES: Experimental rat models of renal transplant have played a pivotal role in renal transplant research. Both intraoperative and postoperative complications during donor nephrectomy and implantation in the recipient can be associated with significant morbidity and mortality. The aim of this paper is to discuss the incidence, pathophysiology, and prevention of complications that occurred in the process of establishment of a rat model of chronic allograft injury at our institution...

BACKGROUND: Graft nephrectomy is recommended in case of early graft failure. When the graft fails more than 3-6 months after transplantation it is current practice to follow a wait-and-see policy. A common indication for graft removal is the graft intolerance syndrome. We aimed to create a risk prediction model for the occurrence of graft intolerance resulting in graft nephrectomy. METHODS: We collected data of kidney transplantations performed in our centre between 1980 and 2010 that failed at least 6 months after transplantation...

BACKGROUND: Right-sided retroperitoneoscopic living donor nephrectomy (LDN) has been shown to be safe for the donor but it is unknown whether the short renal vein is associated with complications or an impaired long-term outcome in the recipient. METHODS: In this retrospective cohort study, consecutive transplant recipients after retroperitoneoscopic LDN were enrolled. Complications occurring within 1 year were classified according to the Clavien-Dindo Classification for Surgical Complications and analysed using multivariable logistic regression...

BACKGROUND: Kidney-related unknown vascular injuries are rare and usually diagnosed only after reperfusion. Hemorrhage that makes in situ reconstruction impossible can lead to graft loss. In an era of organ shortage and an increasing number of patients on the waiting list for transplantation, a kidney graft salvage procedure consisting of graft nephrectomy, reperfusion, reconstruction, and reimplantation should be undertaken whenever possible as a contribution to extending the organs available for transplantation...

INTRODUCTION: Existing methods to predict recipient allograft function during deceased-donor kidney procurement are imprecise. Understanding the potential renal reparative role for monocyte chemoattractant protein-1 (MCP-1), a cytokine involved in macrophage recruitment after injury, might help predict allograft outcomes. METHODS: We conducted a sub-study of the multicenter prospective Deceased Donor Study cohort, which evaluated deceased kidney donors from five organ procurement organizations from May 2010 to December 2013...

BACKGROUND The term nutcracker phenomenon (NCP) elucidates anatomical structure and hemodynamics, whereas nutcracker syndrome (NCS) refers to clinical manifestations. We present three cases of similar clinical features of hematuria and flank pain with different clinical outcomes. CASE REPORT Case 1: A 36-year-old Caucasian female with a past medical history (PMH) of HIV infection presented for evaluation of hematuria. Computed tomography (CT) without contrast showed pelvic venous congestion and narrowing of the extra-renal left renal vein (LRV)...

Kidney transplantation is recognised as the gold standard treatment of end-stage renal disease in most children, with excellent graft survival rates. When graft failure occurs, renal transplant recipients (RTRs) have the option of removal of the transplant (graft nephrectomy [GN]), or leaving the failed transplant in situ. The aims of this review are to discuss the indications for GN, surgical techniques, outcomes after GN (including risks of allosensitisation and the impact on subsequent transplants), and the possible role of routine GN in the asymptomatic RTR with a failed renal allograft...

Mayer-Rokitansky-Küster-Hauser syndrome is a rare disorder consisting of vaginal aplasia and other müllerian duct abnormalities. Urinary tract malfor-mations possibly leading to renal failure are also common. For these patients, kidney transplant remains the best option. However, aberrant anatomy and scarring from previous operations may actually preclude successful implantation of the graft. In this setting, careful pretransplant evaluation with high-resolution imaging studies and multidisciplinary planning are mandatory...

Background: Granulomatous interstitial nephritis (GIN) is uncommon in native kidneys, and descriptions in allografts are few. We report clinical and pathologic findings in 22 allograft recipients with GIN identified in renal allograft biopsies and nephrectomies. Methods: Renal allografts with GIN were retrieved from the pathology files of two academic medical centers. Available clinical and pathologic data were compiled retrospectively for a 23-year period. Results: GIN was present in 23 specimens from 22 patients (15 males and 7 females) with allograft dysfunction [serum creatinine averaged 3...

Primary hyperoxaluria type 1 (PH1) is a rare liver enzymatic defect that causes overproduction of plasma oxalate. Accumulation of oxalate in the kidney and subsequent renal failure are fatal to PH1 patients often in pediatric age. Combined liver and kidney transplantation is the therapy of choice for end-stage renal disease due to PH1. Levels of plasma oxalate remain elevated for several months after liver transplantation, as the residual body oxalate is slowly excreted. Patients with persistent hyperoxaluria after transplant often require hemodialysis, and accumulation of residual oxalate in the kidney can induce graft dysfunction...

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...

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...
