Univariate survival analysis was followed by adjusted Cox-regressional hazard model. Covariates selected via univariate regression were added to the model via forward selection, significance level P = 0.3. The warm ischemic threshold was clinically set at 30 min. Points were given to each predictor in proportion to their hazard ratio. Using this model, the DCD-RI was calculated. The cohort was stratified to predict graft loss risk and respective graft survival calculated.RESULTS DCD graft survival predictors were primary indication for transplant(P = 0.066), retransplantation(P = 0.176), MELD > 25(P = 0.05), cold ischemia > 10 h(P = 0.292) and donor hepatectomy time > 60 min(P = 0.028).According to the calculated DCD-RI score three risk classes could be defined of low(DCD-RI < 1), standard(DCD-RI 2-4) and high risk(DCD-RI > 5) with a 5 years graft survival of 86%, 78% and 34%, respectively.CONCLUSION The DCD-RI score independently predicted graft loss(P < 0.001) and the DCD-RI class predicted graft survival(P < 0.001).展开更多

Kidney transplantation offers the best solution for the problem. The shortage of donor kidney is even bigger problem due to transplantation being one of the routine procedures. The use of deceased donor definitely increases the pool of donor with excellent immediate and long-term follow-up proven results. Aim: The aim is to analyze and summarize the outcome of Kidney transplantation. Methods & Materials: A total of 78 cases of Kidney Transplantation were selected for the study and categorized as: Group I—41 (living Donor), Group II—23 (DCD) & Group III—15 (DBD). Perspective study was done with clean data recorded & maintained pre-operatively, post-operatively and follow-up from Jan 2011 to Dec 2015 in our hospital. Post-operative graft status, complications and at least 1-year follow-up were area of main focus. Results: All patients underwent successful kidney transplantation. In Group I, the number of living donor kidney transplantation is 41 whereas in Group II (DCD) & III (DBD), the number of deceased donor transplantation is 23 and 15 respectively. The Normal functioning of graft (NGF) was 38 (87.8%), 16 (69.6%) & 11 (73.3%) in Group I, II & III respectively along with Poor Graft function (PGF) in Group I—4 (9.7%), II—5 (21.7%) & III—2 (13.3%) managed by continuing dialysis. Delayed graft function (DGF) was noted I-1 (2.4%), II-2 (8.6%) & III-1 (6.6%) in respective group, which returned to normal function post intervention. Therefore, 1<sup>st</sup> year graft survival was >93% [(Group I (97.6%), Group II (95.6%) & Group III (93.3%) respectively]. Manageable surgical complication were found in Group I—8 (19.5%), Group II—5 (21.7%) & Group III—2 (13.3%) like hematoma, hydronephrosis, leakage except one emboli related nephrectomy of transplanted kidney & one pneumonia led death in Group II. The overall survival was greater than 90% [(Group I (97.6%), Group II (91.3%) & Group III (93.3%展开更多
