Appropriate training in paediatric nephrology is a comprehensive approach designed to develop skills and capabilities to deal with the following basic components of medical care: (1) medical competence for clinical and research activities; (2) interpersonal relationships directed at maintaining patients' freedom and autonomy; and (3) adequate incorporation of technological, financial and managerial aspects of paediatric nephrology services. Inappropriate training causes frequent, dramatic and paradoxical negative feedback in developing countries: shortage of functioning medical equipment, skilled manpower and trained paediatric nephrologists co-exist with unused high-cost medical equipment and loss of skilled health care professionals. Appropriate training, tailored to the needs and resources of developing countries, could be an efficient way to develop high-quality paediatric nephrology care. Efficient training must develop self-reliant, self-sufficient and skilled health care professionals in the local economic, educational, technological and political context. Regional and international co-operation is essential to promote adequate training in paediatric nephrology. Developing countries lack an effective and accurate information communication network for selecting modern technology for paediatric nephrology. The development of this network through international co-operation, is an urgent requirement.
