Peritoneal dialysis is a technique of extra renal purification in its own right, it represents an excellent alternative to haemodialysis especially in the paediatric population, unfortunately it is still denigrated by patients who panic at the idea of being alone with their disease and largely prefer the comfort that haemodialysis provides. The role of the nephrologist is to reassure his patient and to guide him on the path of home extra renal cleansing, it is clearly imperative that the first adherent must be the practitioner and that passes by a total control of this technique. Through this manuscript and in six steps I propose a simple and efficient training allowing you to make your first steps in peritoneal dialysis and in total safety.
