Abstract
INTRODUCTION The shortage of kidney transplants encourages the expansion of the limits of eligibility criteria for donation. Many donors who are brain dead display acute renal failure at the time of death; is this a real contraindication to harvesting? The aim of this study was to assess kidney graft survival from donors after brain death with confirmed acute renal failure, with or without anuria previous donation. MATERIALS AND METHODS All of the transplants performed in two university hospitals between 2010 and 2017 were analyzed retrospectively. All patients who underwent single kidney transplant from a brain-dead donor with acute renal failure (ARF) were included in this study. ARI was defined here by a decrease over 50 % of glomerular filtration rate (GFR) to a threshold below 45mL/min/1.73 m2 at the time of kidney procurement. Kidney graft survival, incidence of delayed graft function (DGF) and the GFR at 12 months were analyzed. Analysis of kidney transplant survival based on pre-implantation biopsies was additionally done. RESULTS One hundred and sixty four patients were transplanted with a kidney from donor with ARF during the selected period. At the admission in ICU the average GFR was 67,7±19mL/min/1,73m2. At the time of donation, the average age of donors was 56.4±17.7 years, the GFR was 33.7±8.0mL/min/1.73 m2 16 % of donors were anuric. Cold ischemia time (CIT) was 16.8±5.0hours. The average age of recipients was 55.6±14.1 years. 81 % of the cases were primary transplants. Graft function took place within 7.8±9.4 days after transplantation. There were two non-primary functions (PNF). One hundred and fifty two patients (93 %) had a functional graft at 12 months. The mean GFR at 12 months was 46.8±20.1mL/min/1.73 m2 and 122 patients (73 %) had a GFR greater than 30mL/min/1.73 m2. Seventy-one percent of preimplantation biopsies revealed acute tubular necrosis (ATU); no cortical necrosis was observed. Survival of theses grafts was 85 %, comparable to the total population of study (P=0,21) CONCLUSION: The acute renal failure of the brain-dead donor should not alone be systematically a contraindication to harvesting and kidney transplantation.

Single bilateral ovarian venous return in uterine transplant: Validation in an orthotopic auto-transplant model in the Yucatan minipig. J Gynecol Obstet Hum Reprod 2021; 50:102059. [PMID: 33421624 DOI: 10.1016/j.jogoh.2021.102059] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 12/12/2020] [Accepted: 12/30/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND Uterine transplant (UT) represents an opportunity to treat absolute uterine infertility. However, the use of uterine veins for venous return, in addition to ovarian veins, significantly increases the risk of ureteral wounds in the living donor and UT time for the recipient. Our aim was to demonstrate that dual ovarian venous return is sufficient for graft viability and survival. METHODS Uterine orthotopic auto-transplant was performed under general anaesthesia in six Yucatan minipig sows. The uterus graft was implanted with termino-lateral anastomoses between the ovarian and external iliac veins, and between the uterine and external iliac arteries, respectively. RESULTS The macroscopic physical aspect of the graft was adequate in 83 % of the sows (5/6) 30 min after reperfusion with a surgical time of 439±54 min (mean anastomosis time: 153±49 min). Two sows died the day after surgery. In the four remaining sows, two uteri were necrotic and two were adequately vascularized on Day 7. CONCLUSIONS the learning curve was relatively fast, the sole use of bilateral ovarian venous return is possible and might reduce post-surgery morbidity in human living donors as well as UT time for the recipient.

Abstract
OBJECTIVE The objective of this study was to analyze early, late complications and outcomes following expended criteria donors (ECD) kidney transplantation compared to standard donors. MATERIALS AND METHODS We performed a retrospective study including 470 patients who received a kidney transplant between 2005 and 2016. Expended criteria donors were defined following the United Network of Organ Sharing criteria. In each group, length of stay, delayed graft function, surgical site infection, acute rejection, surgical complications by type and according to Clavien and Dindo classification were analyzed in univariate and multivariate analysis. The impact of ECD transplant on transplant and patient survival was assessed using a Cox proportional regression model. RESULTS One hundred and ninety seven (41.9%) patients received ECD kidney. The mean follow-up was 61,4 months (22.4-93.89). Patients with ECD transplant presented more delayed graft function (HR=2.1 (1.1-3.68), P=0.008) but the rate of complications including surgical complications was not different. Patients and transplant survival were decreased in ECD transplant group (P=0.005 et 0.001 respectively). In multivariate analysis ECD kidney was an independent factor only associated with decreased transplant survival (HR=1.81 (1.1-2.98), P=0.029) but not with patient survival. CONCLUSION ECD kidney transplantation was not associated with increased postoperative complications but a higher rate of delayed graft function. Nevertheless, it was associated with a decreased transplant survival. The use of pulsatile perfusion machine for explanted criteria transplant should be evaluated to improve these results.
