From 1980 onwards chronic dialysis (CD) and kidney transplantation (KT) are accessible for the entire population.


The aim of this study is to describe the trends in the incidence (I), the prevalence (P) and the survival of patients on KRT over the last 40 years.


The P increased from 41 to 1227 pmp (Fig 1). The P on CD increased from 38 on 1981 to 820 pmp in 2020. The P of patients on KT increased from 3 on 1981 to 407 pmp in 2020. The growth of the I and P of CD and KT was higher in the first 2 decades (1981-2000) (278% vs 48%, 533% vs 113%, 1592% vs 23% and 3066% vs 291%) (Fig 2). The growth of the P rate of KT was 10 times higher than the CD P rate. The age on admission to CD increased from 44.3±13.5 in 1981 to 62.2±17.1 years in 2020, while those over 65 years increased from 3.0 to 52.4%. The crude M on CD increased from 14.8 in 1993 to 17.0/100 patient-y, but no changes were observed in the adjusted analysis. The M rate in CD was 17 times higher than that of the general population (Table 1).


The I and P of patients with CKD on KRT in Uruguay have increased between 1981 and 2020 with a higher percentage growth in the P rate of KT. Despite the increasing admission of patients older than 65 years, M has remained stable in recent years.
