The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal. We decided to utilize the left kidney for a 25-year-old male patient with end-stage renal disease, and following the ex vivo repair using the recipient epigastric vessels and saphenous veins, we completed the transplantation in the right pelvic fossa...

BACKGROUND: Sleep-disordered breathing (SDB) is common in patients with end-stage renal disease (ESRD). SDB is associated with comorbidities such as hypertension, diabetes mellitus, and obesity, interplaying with metabolic derangements in the form of uremia, acidosis, and hypervolemia. Renal transplant has been observed to correct most of these metabolic derangements and to control progression of comorbidities. While SDB is highly prevalent among patients in the pretransplant stage, it remains to be seen whether the beneficial aspects of transplant are extended to improvement in SDB in patients with ESRD...

Few studies have examined the long-term risks of kidney removal to donors despite the increase of frequency in kidney transplantation. This is the 1st study to develop prediction models of chronic kidney disease (CKD) for the 1-year period after donor nephrectomy in living donors. A prospective cohort of patients who underwent donor nephrectomy from March 1, 2006, to December 31, 2016, at the Severance Hospital, Seoul, South Korea, was used. CKD was defined as a glomerular filtration rate (GFR) <60 mL/min/1...

BACKGROUND: The health care costs to evaluate, perform surgery, and follow a living kidney donor for the year after donation are poorly described. METHODS: We obtained information on the health care costs of 1099 living kidney donors between April 1, 2004 and March 31, 2014 from Ontario, Canada using comprehensive health care administrative databases. We estimated the cost of 3 periods of the living donation process: the predonation evaluation period (start of evaluation until the day before donation), perioperative period (day of donation until 30-days postdonation), and 1 year of follow-up period (after perioperative period until 1-year postdonation)...

The Luminex test can detect low levels of donor-specific antibody (DSA) that cannot be detected by flow-cytometric crossmatching (FCXM) in kidney transplantation (KT). This study evaluated the impact of DSA on clinical outcomes in KT recipients negative on FCXM. Of 575 consecutive patients who underwent living donor KT between January 2013 and July 2016, 494 (85.9%) were DSA-negative and 81 (14.1%) were DSA-positive. Although rates of acute cellular rejection (ACR) at 1 year were similar in the two groups (P = 0...

Acceptable outcomes of donor-specific antibody (DSA)-positive living kidney transplantation (LKT) have recently been reported. However, LKT in crossmatch (XM)-positive patients remains at high-risk and requires an optimal desensitization protocol. We report our intermediate-term outcomes of XM-positive LKT versus XM-negative LKT in patients who underwent LKT between January 2012 and June 2015 in our institution. The rate of acute antibody-mediated rejection (ABMR) within 90 days post-operation, graft function, and patient and graft survival rates at 4 years were investigated...

BACKGROUND: Pretransplantation soluble CD30 (sCD30) has been shown to be a good predictor of acute rejection (AR) and graft loss. This study aimed to evaluate the effectiveness of sCD30 measured pretransplant and up to 6 months after transplantation as a predictor of AR, graft loss, and survival at 5 years post-transplantation. Subjects were patients receiving living donor renal transplants at Bonsucesso Federal Hospital (Rio de Janeiro) in 2006 and between August 2010 and May 2011. METHODS: sCD30 was analyzed in samples collected pretransplantation and 7, 14, and 21, 28 days and 3, 4, 5, and 6 months post-transplantation from 73 kidney recipients...

BACKGROUND: With the rising prevalence of living-donor kidney transplantation, evaluation of factors correlated with renal function in the donor-recipient pair constitutes a main goal for kidney transplantation clinicians. Our objective was to analyze the more relevant donor characteristics that contribute to donor and recipient estimated glomerular filtration rates (eGFR) after 1 year. METHODS: We evaluated 48 consecutive donor-recipient pairs from our unit. RESULTS: Mean donor age was 46 ± 11 years, with 71% being women...

Renal transplant scintigraphy, performed in a 23-year-old man who had renal graft from a living donor, showed nearly normal perfusion and moderately low function of the graft. But the margins of the graft were blurred, and it was interestingly appearing enlarged late in the study. Ultrasound demonstrated a hypoechoic rim surrounding the whole kidney. Biopsy revealed necrosis besides normal cortical tissue. Necrosis was thought to be limited to the subcapsular cortical area. It should be considered that these scintigraphic findings could be due to greatly reduced and delayed perfusion of edematous subcapsular necrotic area of the graft even in normal perfusion images...

Kidney transplantation is now a mainstream therapy for end-stage renal disease. However, with approximately 96,000 people on the waiting list and only one-fourth of these patients achieving transplantation, there is a dire need for alternatives for those with failing organs. In order to decrease the harmful consequences of dialysis along with the overall healthcare costs it incurs, active investigation is ongoing in search of alternative solutions to organ transplantation. Implantable tissue-engineered renal cellular constructs are one such feasible approach to replacing lost renal functionality...

BACKGROUND: Kidneys from non-white donors have inferior outcomes, but it is unclear if ethnicity matching between donors and recipients achieves better post kidney transplant outcomes. METHODS: We undertook a retrospective, population cohort study utilising UK Transplant Registry data. The cohort comprised adult, kidney-alone, transplant recipients receiving their first kidney transplant between 2003-2015, with data censored at 1st October 2016. We included 27,970 recipients stratified into white (n = 23,215), black (n = 1,679) and south Asian (n = 3,076) ethnicity, with median post-transplant follow-up of 1,676 days (IQR 716-2,869 days)...

Focal segmental glomerulosclerosis (FSGS) is a histologic lesion resulting from a variety of pathogenic processes that cause injury to the podocytes. Recently, mutations in more than 50 genes expressed in podocyte or glomerular basement membrane were identified as causing genetic forms of FSGS, the majority of which are characterized by onset in childhood. The prevalence of adult-onset genetic FSGS is likely to be underestimated and its clinical and histological features have not been clearly described. A small number of studies of adult-onset genetic FSGS showed that there is heterogeneity in clinical and histological findings, with a presentation ranging from sub-nephrotic proteinuria to full nephrotic syndrome...

Background: Recently, transplant societies have had to change their allocation policies to counter global organ shortages. However, strategies differ significantly and long-term outcomes and cross-regional applicability remain to be evaluated. Methods: Therefore, we retrospectively analysed the Kidney Donor Profile Index (KDPI) of 987 adult kidney transplants at our centre using data from the Organ Procurement and Transplantation Network (OPTN) as a reference. Results: In our cohort, the median KDPI was 66%, with a higher proportion of >85% KDPI kidneys compared with the US cohort (32...

Robotic-assisted kidney transplantation (RKT) with the Da Vinci (Intuitive, USA) platform has been recently developed to improve outcomes by decreasing surgical site complications and morbidity, especially in obese patients. This potential paradigm shift in the surgical technique of kidney transplantation is performed in only a few centers. For wider adoption of this high stake complex operation, we aimed to develop a procedure-specific simulation platform in a porcine model for the training of robotic intracorporeal vascular anastomosis and evaluating vascular anastomoses patency...

The practice of kidney paired donation (KPD) is expanding annually, offering the opportunity for live donor kidney transplantation to more patients. We sought to identify if voluntary KPD networks such as the National Kidney Registry (NKR) were selecting or attracting a narrower group of donors or recipients compared to national registries. For this purpose, we merged data from the NKR database with the SRTR database from February 14, 2008 to February 14, 2017, encompassing the first 9 years of the NKR. When compared to all UNOS live donor transplants (49,610), all UNOS living unrelated transplants (23,319), and all other KPD transplants (4,236), the demographic and clinical characteristics of NKR transplants (2,037) appear similar to contemporary national trends...

BACKGROUND: Postreperfusion syndrome (PRS) has been shown to be related to postoperative morbidity and graft failure in orthotopic liver transplantation. To date, little is known about the impact of PRS on the prevalence of postoperative acute kidney injury (AKI) and the postoperative outcomes after living donor liver transplantation (LDLT). The purpose of our study was to determine the impact of PRS on AKI and postoperative outcomes after LDLT surgery. METHODS: Between January 2008 and October 2015, we retrospectively collected and evaluated the records of 1865 patients who underwent LDLT surgery...
