RESUMEN
In 2005, renal replace treatment (dialysis and transplant) was necessary for about 40,000 people, without being known the number accurate and either their basic characteristics, such as: time in treatment, modality or treatment changes. The presented data cover the 76% of the Spanish population and are the result of the cooperation among technicians of registries, nephrologists and transplant coordinations. 4,125 people started RRT in 2005, the total estimated acceptance rate for renal replacement therapy in adults in Spain was 126 pmp and regarding other European countries it locates us in an intermediate area. The incidence rate seems to keep stable in the last years although there were some differences among communities (from 104 pmp in Castile and Leon to 186 pmp in Canary Islands). Diabetes Mellitus is the most diagnosed cause of renal failure in 2005, more than 20% of patients, followed by vascular diseases. The estimated prevalence of renal replacement therapy in Spain at the end of 2005 was 903 pmp, with important variations among communities (from 806 pmp in Cantabria to 1056 pmp in Valencia Region). The 47% of prevalent RRT patients had a functioning transplant. Mortality on haemodialysis and peritoneal dialysis was 13.7% and 10.8% respectively. Mortality on transplant was 1.3%, one of the lowest values registered so far. Mortality on renal replacement therapy was around 5% among patients from 45 to 64 years, 11% between 65 and 74 years and 19% among the patients older than 75 years.
