The management of chronic renal failure by dialysis and transplantation has now become an established form of treatment in many parts of the world. However, these forms of treatment have brought with them problems in relation to the selection of patients, economics, clinical problems such as hypertension, encephalopathy, anaemia and renal bone disease, and psychological and social problems. The management of haemodialysis has changed over the years with developments in dialysers, vascular access and the duration of dialysis. Although the overall survival from renal trans­ plantation has changed little in the past four or five years, there are hopes of improvements in relation to tissue typing and enhancement. Perhaps the most important aspect in the management of chronic renal failure is the multi-disciplinary approach. Nursing and medical staff work closely with dialysis technicians, engineers, dietitians, local authority per­ sonnel, social workers and with the relatives of the patients. The symposium was planned to draw together representatives from all disciplines involved in the care of patients with chronic renal failure. One of the most relevant sessions was that in which two patients with chronic renal failure described their experience.

The last 20 years has seen an enormous increase in our knowledge about the management of patients with terminal renal failure. Despite this, even the most successful dialysis and transplant patients require long term specialist supervision so that renal units will have an incremental work load until the death rate of patients undergoing treatment equals the rate of intake of new patients. Furthermore, innumerable conditions which were once regarded as contraindications to therapy may no longer be seen in this light, so that the number of new patients coming forward for treatment each year is increasing rapidly. Dialysis and transplantation are expensive forms of treatment, in terms of staff, facilities and consumables, and it is therefore inevitable that there will be problems in providing treatment for all who need it. These will be particularly acute in times of economic crisis. This book contains the proceedings of a conference which was set up to explore the difference between the supply and the demand for treatment in the United Kingdom, to compare the situation with that in other countries, to explore possible solutions and possibly assign responsibility for the shortfall and to examine the practical and moral implications of our failure to treat the treatable.
