Purpose Intra-operative insults may subject living kidney transplants to poor outcomes. Therefore, we investigated whether intra-operative recipient and donor hemodynamics could act as predictors of delayed graft function and subsequent outcomes. Materials and Methods Living kidney donors and recipients from 2010-2016 at this institution underwent a retrospective chart review. Graft function by post-operative day 7 was used to classify recipients as delayed graft function (need for dialysis), slow graft function (creatinine > 2.5) and good function. Groups were analyzed for intra-operative hemodynamic differences and at one year, incidence of rejection, graft function and survival were compared. Results A total of 111 living renal transplants were performed. Average recipient age was 50 and just over halfwere male (53%). 9% (n=10) and 10% (n=11) developed delayed graft function and slow graft function, respectively. Minimum recipient post re-perfusion central venous pressure ≥12 mmHg was associated with poor graft function (delayed graft function/slow graft function/good function=67%/56%/24%, p=0.009), while intra-operative hypotension (systolic <90 mmHg or diastolic <50 mmHg) was not. Delayed graft function and slow graft function had higher incidences of rejection than good function (30% and 36% vs 9%, p=0.012). Graft function and survival were similar. One patient died with a functioning graft. Conclusions This single center retrospective study suggests that a post re-perfusion central venous pressure ≥12 mmHg is associated with delayed graft function. Show less

This review article provides ethical guidance for determining which kinds of financial benefits provided to living organ donors are ethically appropriate. It does so by way of ethical analysis of a policy case study: the National Kidney Registry (NKR) has implemented a donor insurance program to all its living donors. Is such a policy ethically supportable, or is it an unethical practice? The article proceeds as follows. First, a framework for grounding the ethical commitments of transplant programs is defended. It is argued that this framework can be accepted by all who work in transplant medicine, regardless of differences in ethical theory preference or background. Second, from this framework two ethical principles are formulated. (1) Living donors should, as far as possible, not be worse off for donating. (2) Disincentives towards donation should be removed as much as possible. Third, issues with unethical incentives are explored: undue inducement, commodification of the body, potential decreased organ donation rates, and potential exploitation of vulnerable populations. Lastly, these ethical considerations are applied to the policy change at the NKR, showing that the NKR policy change appears to be ethically supportable. Financial benefits provided to donors are ethically sound if they are in keeping with principles (1) and (2), and do not cause undue inducement, commodification, decreased organ donation, or exploitation. It is ethically appropriate for transplant programs to institute as well as study such programs with the goal of serving the welfare and interests of patients, donors, and the general public.

Background Doppler ultrasonography can evaluate vascular and renal parenchymal disorders. In this study, color Doppler patterns in transplanted kidneys were compared with histological diagnosis to develop diagnostic models for transplanted kidney failure. Method 45 kidney transplant patients participated in this prospective study (16 suffered acute tubular necrosis (ATN), and 29 had transplant rejection). All patients had color-Doppler ultrasonography to measure kidney parameters and Doppler indices. Serum creatinine levels also assessed the transplanted kidney's function. Result Ultrasound showed a significant difference between the two groups in iliac and interlobar PSV. The ROC analysis showed a high diagnostic value of the iliac artery PSV, in distinguishing ATN from kidney transplant rejection. Serum creatinine level correlated directly with transplanted kidney volume, renal cortical thickness, and transplanted kidney length, and inversely with interlobar artery PSV and EDV. In graft rejection patients, the only significant inverse correlation was found between serum creatinine level and PSV of the iliac artery and EDV of the intrelobar artery. Discussion and conclusion The iliac artery PSV can differentiate between ATN and rejection after renal transplantation. Evaluation of renal metric parameters along with PSV and EDV of the interlobar artery (in patients with ATN) and iliac artery and interlobar artery (in transplant rejection) help determine renal dysfunction.

There are over 100,000 people waiting for life saving organ transplants in the United States. To put this in perspective, even the largest football stadium in the U.S. could not fit this number of people. In 2021 alone, 6,000 people died while waiting for a transplant. Every day, 17 people die waiting, and every 10 minutes, another person is added to the waiting list (“Organ Donation Statistics,” 2023). These numbers are expected to rise due to the lack of organs available, and the increasing need for organs, especially kidneys. Show less
