Intermediate-term outcome of renal retransplants in the cyclosporine era.

To determine the influence of selected parameters on intermediate-term outcome of renal retransplants, univariate and multiple regression analyses were performed on all 100 consecutive cyclosporine treated retransplants performed between 1984 and 1990 (mean follow up, 4.6 +/- 2.3 years). Actual 1 year and actuarial 5 year graft survivals were higher in living compared with cadaver donor transplants (84% and 79% vs 69% and 56%, respectively; p < 0.05). Among cadaver donor transplant recipients, allografts with immediate early function had better 1 and 5 year graft survivals when compared with those with delayed function (81% and 62% vs 59% and 38%, respectively; p < 0.05). Recipients with acute rejection had inferior 1 year and 5 year graft survivals when compared with rejection free patients (65% and 35% vs 80% and 57%, respectively; p < 0.05). Graft survival time of primary transplants was also a significant predictor of retransplant outcome with 1 and 5 year graft survivals of 50% and 36%, respectively, in patients in whom primary grafts survived less than 3 months, compared with 75% and 58% in those in whom grafts survived longer than 3 months (p < 0.05). Recipient age, race, renal disease, and levels of panel reactive antibodies had no effect on intermediate-term outcome. In a multiple regression analysis, delayed graft function, acute rejection, and primary graft survival time less than 3 months correlated inversely with long-term survival of retransplants (multiple r = 0.65). A total of 39 grafts were lost due to rejection (22), sepsis (6), graft nonfunction (5), death with a functioning graft (4), noncompliance (1), and recurrent renal disease (1).(ABSTRACT TRUNCATED AT 250 WORDS)
