Chronic peritoneal dialysis, especially continuous ambulatory peritoneal dialysis, is now a modality of treatment for patients with end stage renal failure. The proportion of patients varies considerably from country to country. Non medical considerations seem to be the main reason for the limited development of the treatment modality. Most of available reports point out no difference in patient or technique survivals on hemodialysis or peritoneal dialysis. Age, diabetes mellitus, cardiovascular diseases, infections complications (peritonitis and exit-site infections) impact on mortality and morbidity (number of hospital days per patient per year). The probability of death or dropout is much higher for patients with diabetes and patients in older age groups. Most patients with end stage renal failure, especially those waiting for a kidney transplant, are suitable for peritoneal dialysis.
