title: [Patients returning after transplantation].
abstract: Numerous reports have dealt with patient survival and prognostic factors after renal replacement therapy. However, few data exist for patients after a failed renal transplant and who start dialysis again. With this purpose, we retrospectively studied 36 patients who returned to dialysis after a mean transplantation time of 42.8 +/- 7.8 months. Actuarial patient survival on dialysis after the failed renal transplant (D2) was 78%, 74%, 69% and 41% at 1, 2, 3 and 5 years after restarting dialysis respectively. In comparison, survival of patients who started dialysis without a previous history of a renal transplant showed rates of 91%, 85%, 79% and 64% at 1, 2, 3 and 5 years respectively. The difference was statistically significant only at one year after beginning dialysis therapy (78% vs. 91%, p < 0.025). There were no differences in plasma urea concentration by the time of starting both first (D1) and second (D2) dialysis treatments (37.4 +/- 1.9 and 38.8 +/- 2.9 mmol/L respectively). Instead, a statistically significant difference was found between corresponding serum creatinine values (1100.1 +/- 47.1 and 856.9 +/- 50.0 mumol/L respectively, p < 0.05). When actuarial survival and serum creatinine values at the start of D2 were analyzed, there was a statistically better survival at 1 year for patients with serum creatinine values under 900 mumol/L, as compared with those above 900 mumol/L (85% vs. 52%, p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
