ABSTRACT
Objective:To establish donor liver quality related risk factors for the loss of function of transplanted liver.Methods:The data of donors and recipients of liver transplantation at the Organ Donation and Transplantation Center of the First Affiliated Hospital of Sun Yat-sen University from Nov 2011 to Dec 2018 were analyzed retrospectively. Propensity score matching (PSM) was performed to evaluate and screen the data of donors and recipients, in order to balance the covariates.Results:Of the organ donation, there were 70 males and 20 females , aging (40.6±16.3) years. Of the liver transplantation recipients, there were 70 males and 20 females , aging (41.8±20.3) years. Liver dysfunction after transplantation was significantly correlated with the following variables: the donor's CPR time( t=0.429, P=0.000), 15-minute retention rate of indocyanine green ( χ2=67.151, P=0.000), liver function grading ( χ2=54.154, P=0.000), bullae fatty liver grading ( χ2=8.120, P=0.017), vesicular fatty liver grading ( χ2=16.000, P=0.001), ICU stay time ( χ2=14.900, P=0.001)and serum creatinine level ( χ2=44.685, P=0.000). The donor scoring system was established in our studying. For the 90 organ donation cases, the donated liver quality were classified into four levels,which were of good correspondence to the prognosis of the recipients. Conclusion:This donor scoring system and grading standards established by analyzing the high-risk factors of liver dysfunction after transplantation helps evaluate the quality of donor liver in China.
ABSTRACT
Objective To investigate the influence of quality evaluation of donated kidney after citizen's death on prognosis of renal allograft recipients.Methods A retrospective analysis on 577 cases of deceased organ donation/1084 cases of renal transplantation was made in the First Affiliated Hospital of Xi'an Jiaotong University from December 2011 to August 2018.The quality of donor/ donated kidney was evaluated through various aspects,and the prognostic data of renal transplant recipients were summarized and analyzed.Results 1 084 cases of donated kidney transplantation were completed,and the average follow-up time was (14.3 ± 13.5) months.The 1-and 3-year survival rate of transplant recipients was 97.4％ and 92.1％,respectively,and the 1-and 3-year survival rate of transplanted kidney was 94.6％ and 89.2％ respectively.There were significant differences in human/ kidney survival rate and DGF incidence after renal transplantation among those various groups according to the criteria of subdivision of score of points for donor assessment.Conclusion Comprehensive evaluation of donated kidney quality in all aspects has a significant positive effect on improving the effect of transplantation.
