Introduction: The study purpose was to review retrospectively our single-center experience transplanting kidneys from deceased donors (DD) with acute kidney injury (AKI) according to terminal serum creatinine (tSCr) level.

Methods: AKI kidneys were defined by a doubling of the DD's admission SCr and a tSCr ≥ 2.0 mg/dL.

Background: The nonuse rate for kidneys recovered from deceased donors is increasing, rising to 27% in 2023. In 10% of these cases, 1 kidney is transplanted but the mate kidney is not.

Study Design: We conducted a retrospective, single-center cohort study from December 2001 to May 2023 comparing single kidneys transplanted at our center (where the contralateral kidney was not used) to kidneys where both were transplanted separately, at least 1 of which was at our center.

Introduction: There is limited experience transplanting kidneys from either expanded criteria donors (ECD) or donation after circulatory death (DCD) deceased donors with terminal acute kidney injury (AKI).

Methods: AKI kidneys were defined by a donor terminal serum creatinine level >2.0 mg/dL whereas non-ideal deceased donor (NIDD) kidneys were defined as AKI/DCD or AKI/ECDs.

Aim: The influence of dialysis modality and duration on outcomes following simultaneous pancreas-kidney transplantation (SPKT) remains uncertain.

Methods: We performed a single-center retrospective review in 255 SPKT recipients according to dialysis modality (55 preemptive/no dialysis-ND, 70 peritoneal dialysis-PD, 130 hemodialysis-HD) and duration (55 none, 137 < 2 years, 41 2-4 years, 22 > 4 years).

Results: Mean follow-up was 9.

Background: Hypothermic machine perfusion is frequently used in evaluating marginal kidneys with poor perfusion parameters (PPP) contributing to delays in kidney placement or discard. We examined outcomes in deceased donor kidney transplants with PPP compared with those with optimal perfusion parameters (OPP).

Study Design: We conducted a retrospective single-center cohort study from 2001 to 2021 comparing PPP (n = 91) with OPP (n = 598) deceased donor kidney transplants.

Introduction: Long-term outcomes of kidney transplantation from deceased donors (DDKTs) with terminal acute kidney injury (AKI) are not well defined.

Methods: Single center retrospective review of DDKTs from 1/31/07-12/31/19. AKI kidneys were defined by a doubling of the donor's admission serum creatinine (SCr) level AND a terminal SCr ≥2.

Introduction: The influence of sex on outcomes following simultaneous pancreas-kidney transplantation (SPKT) in the modern era is uncertain.

Methods: We retrospectively studied 255 patients undergoing SPKT from 11/2001 to 8/2020. Cases were stratified according to donor (D) sex, recipient (R) sex, 4 D/R sex categories, and D/R sex-matched versus mismatched.

Background: Complications leading to early technical failure have been the Achilles' heel of simultaneous pancreas-kidney transplantation (SPKT). The study purpose was to analyze longitudinally our experience with early surgical complications following SPKT with an emphasis on changes in practice that improved outcomes in the most recent era.

Study Design: Single center retrospective review of all SPKTs from 11/1/01 to 8/12/20 with enteric drainage.

Background: Allograft nephrectomy (AN) has been associated with considerable perioperative morbidity. We aimed to determine if preoperative angiographic kidney embolization (PAKE) to induce graft thrombosis before AN improves outcomes.

Study Design: We reviewed adult kidney transplant alone patients who underwent AN at a single center from 2002 to 2020 and compared perioperative outcomes for patients with and without PAKE.

Unlabelled: The influence of African American (AA) recipient race on outcomes following simultaneous pancreas-kidney transplantation (SPKT) is uncertain.

Methods: From 11/01 to 2/19, we retrospectively studied 158 Caucasian (C) and 57 AA patients (pts) undergoing SPKT.

Results: The AA group had fewer patients on peritoneal dialysis (30% C vs.

Background: Decreasing kidney discards continues to be of paramount importance for improving organ transplant access, but transplantation of nonideal deceased donor kidneys may have higher inherent risks of early graft loss (EGL). Patients with EGL (defined as graft failure within 90 days after transplant) are allowed reinstatement of waiting time according to United Network for Organ Sharing (UNOS) policy. The purpose of this study was to examine outcomes for patients experiencing EGL.

Background: Decisions on who requires simultaneous liver-kidney (SLK) transplantation are controversial. United Network for Organ Sharing implemented a "safety net" in 2017 providing prioritization on the kidney waitlist for patients with renal failure after liver transplantation. We aimed to compare survival after early kidney after liver transplantation (KALT) and SLK.

Background: Association between the apolipoprotein L1 gene (APOL1) and nephropathy has altered the epidemiology of chronic kidney disease. In addition, donor APOL1 genotypes play important roles in the time to allograft failure in kidneys transplanted from deceased donors and the safety of living kidney donation.

Methods: This article reviews genetic testing for inherited kidney disease in living kidney donors to improve donor safety.

Background: The study purpose was to analyze outcomes in recipients of pediatric dual en bloc (PEB) kidneys from small pediatric donors (SPDs, age ≤ 3 years) and dual kidney transplants (KTs) from adult marginal deceased donors (DDs) in the context of the Kidney Donor Profile Index (KDPI).

Study Design: This was a single center retrospective review. Recipient selection included primary transplant, low BMI, low immunologic risk, and informed consent.

Background: Despite substantial evidence demonstrating clear benefit, rates of preemptive kidney transplantation (PreKTx) remain low in the United States. Our goal was to identify barriers to PreKTx.

Methods: Using a telephone-administered questionnaire including questions about barriers, timing of referral, timing of education, we retrospectively studied first living donor kidney transplant recipients (2006-2010) at Mayo Clinic, Rochester, MN.

Aims: The aim of this study is to assess the impact of obstructive coronary artery disease (CAD) on outcomes after liver transplantation.

Background: Patients considered for liver transplantation are at an increased risk for CAD. Obstructive CAD is a contraindication for liver transplantation at most centres.

Background: Given high dialysis mortality rates for patients older than 60 years, accepting a kidney with a high Kidney Donor Profile Index (KDPI) score could enable earlier and potentially preemptive transplantation (preKT). However, evidence regarding the risks of high KDPI allografts in older patients is limited. Our objective was to determine the relative benefit for older patients of KDPI greater than 85% transplant either preemptively or not compared with remaining on the waitlist.

Background: Preemptive kidney transplantation (preKT) is associated with higher patient survival, improved quality of life, and lower costs. However, only a minority of patients receives preKT. The aim of this study was to examine changes over the past decade in rates of preKT, focusing on living donor kidney transplantation (LDKT) and specifically recipients who underwent kidney transplantation within 1 year of initiating dialysis.
