Nang cầu thận hay còn gọi là nang Baoman, do nhà khoa học Baoman phát hiện và mô tả nó, thực chất nó là một cái túi gồm 2 lớp mà lớp trong tiếp giáp với búi mao mạch (chính là cầu thận). | 224 Understanding the Complexities of Kidney Transplantation Analyzing long-term graft survival excellent results were observed using the grafts previously selected by biopsy. Graft survival in recipients of histologically evaluated kidneys did not differ significantly from that of grafts from younger donors previously evaluated with biopsy. On the other side survivals were strongly superior to that of elder grafts not pre-operatively evaluated with biopsy. Adopting this score long-term survival of single or dual kidney grafts from donors older than 60 years of age were similarly excellent showing that systematic hystological approach may help to expand the donor-organ pool for kidney transplantation without a contemporaneous lack of results . Karpinski score A New study based on histological aspects Karpinski et al. 1999 was performed on 57 allografts procured by 34 elderly donors age I 60 years with hypertension and or vascular disease. Graft survival of these patients was compared with the results of 57 control recipients selected to have similar baseline demographics but receiving transplants from younger donors. Donor renal pathology was scored 0-3 none to severe disease in four areas Table 3 Glomerulosclerosis tubular atrophy interstitial fibrosis and vascular disease. Vascular disease was composed by two different parameters . arteriolar narrowing and arterial sclerosis . The number of sclerotic glomerules was expressed as a percent of the total number of glomerules available for evaluation. For the vascular lesions both arteries were evaluated separately. However for the final vascular score the most severe lesion of either arterioles or arteries determined the final grade. Each of the 4 compartments was given a score from 0 to 3 the total score was expressed out of 12. A donor vessel score of 3 3 was associated with a 100 incidence of delayed graft function and poor 1-year graft function. Donor and histological graft variables A new model .
