[Historical Archives of Italian Nephrology. "Le Giornate Mediche Triestine del 1952" the first nephrological international meeting held in Italy].

The author came recently across the proceedings volume of a forgotten meeting on renal disease, held in Trieste in 1952. The invited speakers came from Italy, France and Switzerland, and were prominent figures of the European medicine. They dealt with various topics: renal pathophysiology, pathology, diagnosis, and treatment of renal disease. The analysis of the proceedings shows that most of the chosen topics were "hot" for that time and that the papers presented by Italian and foreign speakers were absolutely up-to-date. The discovery of the proceedings of this meeting, followed by other international renal meetings all over Europe, shows that, in spite of the lack of international recognition, Italian nephrologists were active at an early time and maintained a scientific relationship with their foreign counterpart.
