In this study we show the results derived from the processing of the data of the Registry of the patients on peritoneal dialysis that initiated renal replacement therapy in Andalucía between January of 1999 and December of 2008. All the information comes from the base of the Registry of Renal Patients of the Andalucia s Health Service. The results show demographic data, distribution by provinces, etiology of the end stage renal disease, reason for election of the peritoneal dialysis, inclusion or not in list of renal transplant, catheter data, withdraws and their causes, and peritonitis data of 2008. We also analyze in the report, from 1999-2008: annual incidence, diabetes, automatic peritoneal dialysis and peritonitis incidence. Finally we have studied patient and technique survival and factors affecting mortality on peritoneal dialysis, the initial comorbid conditions and its impact in the patient s survival.
