The 50th anniversary of dialysotherapy celebrated by nephrologists around the world in 2012 provided an opportunity for discussion on the role of clinical experience in relation to technological progress in the evolution of dialysis, especially of recently observed inadequate decrease in mortality/morbidity rates of patients on chronic dialysis.
