: Mayor urological complications, fistulae and stenosis, mainly affect the vesicoureteral anastomosis and present in the early post-transplant period. The systematic use of ureteral catheters keeps selecbeing controversial with many groups using them only selectively depending on the existence of pretransplant or intraoperative risk factors. METHODS: We performed a bibliographic review through automatized search in the Medline bibliographic database, as the main bibliographic source, and also in Clinical Key...

We report the case of a human immunodeficiency virus-seropositive patient whose initial kidney transplant failed because of BK polyomavirus-induced nephropathy, and who underwent a second transplantation 3 years later. BK viruria was detected 1 day after transplantation. After 1 month, BK viremia developed along with a donor-specific antibody. After decreasing tacrolimus and mycophenolic acid and 2 courses of intravenous immunoglobulins, BK viremia and donor-specific antibody permanently disappeared, with stable renal function...

BACKGROUND: In patients with failure of an initial arteriovenous fistula (AVF), a subsequent vascular access is needed before hemodialysis (HD) initiation. METHODS: To assess the optimal access strategy after a failed AVF, we linked data from the US Renal Data System with Medicare claims data identifying 21,436 patients ≥ 67 years old who started HD between January 1, 2005, and December 31, 2008, with an AVF placed as their first predialysis access. Of the 10,568 subjects whose AVF failed, 1,796 patients had an AVF placed as a second access predialysis (AVF2 group) and 399 patients had an arteriovenous graft placed as a second access predialysis (AVG2 group)...

BACKGROUND: Despite long-term side effects, calcineurin inhibitors (CNI) remain a cornerstone of immunosuppression in renal transplantation. Few trials assessed the long-term outcome after early CNI withdrawal. METHODS: This intention-to-treat study assessed the 10-year outcome of 108 patients randomly converted from a cyclosporine (CsA)-mycophenolate mofetil (MMF)-prednisone regimen to a dual therapy (CsA-prednisone or MMF-prednisone) at 3 months postgraft. RESULTS: At 10 years, 3...

BACKGROUND/OBJECTIVE: Open aortoiliac grafts have typically been constructed with a short aortic bifurcation sewn near or to the visceral vessels to avoid limb kinking. Similarly, the majority of endovascular bifurcated stent grafts have short aortic main body ranging from 3 to 5 cm. In these patients, endovascular salvage with fenestrated stent grafts is technically challenging because of the short distance between the renal arteries and the flow divider of the graft. Custom fenestrated stent grafts can be extended into the prior open surgical graft or stent graft using a short distal bifurcated stent graft with inverted iliac limb for the contralateral gate...

The ability of kidney transplantation to improve quality of life has made this therapeutic modality the treatment of choice among renal replacement therapies; however, the continuing organ shortage has forced the use of marginal kidneys as a supplementary source of allografts. It has been repeatedly suggested that failed kidney transplant recipients have greater morbidity and mortality compared with dialysis patients with no renal transplant history. Achieving an optimal balance between the advantages of kidney transplant and disadvantages of allografts with marginal quality is a topic of controversy in transplant medicine...

OBJECTIVE: With improvements in medical management and survival of patients with end-stage renal disease, maintaining durable vascular access is increasingly challenging. This study compared primary, assisted primary, and secondary patency, and procedure-specific complications, and evaluated whether the number of interventions to maintain or restore patency differed between prosthetic femoral-femoral looped inguinal access (thigh) grafts and Hemodialysis Reliable Outflow (HeRO; Hemosphere Inc, Minneapolis, Minn) grafts...

PURPOSE: The population of end-stage renal failure patients dependent on hemodialysis continues to expand with an increasing number of patients having an unsuitable cephalic vein or failed radio- and brachio-cephalic fistula. In these patients, the transposed basilic vein to brachial artery arteriovenous fistula (BaVT) provides autologous choice for hemodialysis. The results of basilic vein transposition arteriovenous fistula were assessed. MATERIALS AND METHODS: Three hundred cases of BaVT performed at a single center during the period of January 2005 to December 2011 were reviewed retrospectively...

PURPOSE: To determine the incidence of acute kidney injury (AKI), need for emergent dialysis, and renal graft loss in patients with kidney transplants, who underwent CT examinations with low-osmolality iodine-based contrast material (IBCM). MATERIALS AND METHODS: Our institutional review board approved this retrospective Health Insurance Portability and Accountability Act compliant study. From January 2005 to April 2015, a total of 224 CT examinations were performed using low-osmolality IBCM in patients with kidney transplants...

INTRODUCTION: After a failed transplant, management of a non-functional graft with pain or recurrent infections can be challenging. Transplant nephrectomy (TN) can be a morbid procedure with the potential for significant blood loss. Embolization of the renal artery alone has been proposed as a method of reducing complications from an in vivo failed kidney transplant. While this does yield less morbidity, it may not address an infected graft or refractory hematuria or rejection. We elected to begin preoperative embolization to assess if this would help decrease the blood loss and transfusion rate associated with TN...

Retransplantation accounts for approximately 15 % of the annual transplants performed in the USA, and in the recent International Collaborative Transplant Study report on pediatric patients 15.2 % of the 9209 patients included in the report were retransplant recipients. Although the significant advances in clinical management and newer immunosuppressive agents have had a significant impact on improving short-term allograft function, it is apparent that long-term allograft function remains suboptimal. Therefore, it is likely that the majority of pediatric renal allograft recipients will require one or more retransplants during their lifetime...

BACKGROUND: Rituximab has shown encouraging results for the treatment of kidney transplantation recipients with focal segmental glomerulosclerosis (FSGS) recurrence. However, the correct, opportune, and safe use of rituximab for this indication remains to be determined. METHODS: This multicenter retrospective study reports on 19 new cases aged 35 (15-66) years who developed FSGS recurrence at 12 (1.5-27) days posttransplantation. Initial treatment consisted of plasma exchanges (PE), high doses of calcineurin inhibitors, and steroids...

With the development of kidney transplantation procedure the number of patients returning to dialysis after losing their graft function is gradually increasing. Early return to dialysis after an unsuccessful kidney transplantation is associated with a worse prognosis. Patients with end stage transplanted kidney failure may be qualified again for the treatment of both peritoneal dialysis or hemodialysis. They represent an increased risk of complications as compared to patients without a history of previous kidney transplantation because they usually have high commorbidity, receive immunosuppressive therapy and during re-qualification to dialysis usually have no efficient vascular access or peritoneal catheter implanted...

Access surgeons will encounter patients with functioning transplants who want to lose their fistula, and every dialysis unit sees patients returning after a failed kidney transplant for whom an old fistula is a readily available lifeline. The decision is straightforward in patients with perfectly functioning transplants and disabling complications of their fistula, or in patients with failing transplants and a good fistula. The challenge is to make this decision in patients with good transplant function and an asymptomatic fistula...

Neostigmine can successfully decompress patients with acute colonic pseudo-obstruction (ACPO) who are unresponsive to conservative therapy. However, neostigmine is contraindicated in renal failure, so it is underused in ACPO patients with renal failure who would be otherwise appropriate candidates. We described the first successfully treated case of acute kidney injury (AKI) with neostigmine in a patient with ACPO. A 72-year-old man who underwent a coronary artery bypass graft surgery 11 days prior presented to the emergency room with abdominal distension, peripheral edema, and dyspnea on exertion...

Lifelong immunosuppressive therapy is essential to prevent allograft rejection in transplant recipients. Long-term, nonspecific immunosuppression can, however, result in life-threatening complications and fail to prevent chronic graft rejection. Bone marrow (BM)-derived multipotent mesenchymal stromal cells (MSCs) have emerged as a potential candidate for cell-based therapy to modulate the immune response in organ transplantation. These cells can repair tissue after injury and downregulate many of the effector functions of immune cells that participate in the alloimmune response, converting them into regulatory cells...

BACKGROUND: In end-stage renal disease patients with central venous obstruction, who have limited vascular access options, the Hemodialysis Reliable Outflow (HeRO) Graft is a new alternative with a lower incidence of complications and longer effective device life compared to tunneled dialysis catheters (TDCs). We undertook an economic analysis of introducing the HeRO Graft in the UK. METHODS: A 1-year cost-consequence decision analytic model was developed comparing management with the HeRO Graft to TDCs from the perspective of the National Health Service in England...

We report a case of SMV injury in a critically ill patient. The patient was a 19-year-old woman involved in a motor vehicle collision. Her injuries included grade II splenic and renal lacerations, devascularized and lacerated right and transverse colon, a transected transverse mesocolon, a massive shear injury of her abdominal wall, and two partial SMV transections. At initial damage control laparotomy, the SMV was ligated, the devascularized bowel resected and a temporary abdominal closure applied. At re-operation, a mesocaval shunt using saphenous vein was employed...
