We describe the training itinerary of Dr. Luis Cifuentes, in a time in which Urology lacked of scientific prestige and was a limited field of surgery. His excellent education in basic sciences, his permanent voluntary contact with the most representative scientists of that time, his innovative PhD thesis, and other initiatives, altogether with his inquisitorial character and extraordinary personal aptitudes enabled him to get to Urology with an exceptionally rich burden of knowledge.With the help of excellent national and international mentors he achieved a urological training of such quality that his scientific and professional prestige was immediately recognized, as well as his clinical quality, technical expertise, and research rigor. All these led him to leave an admirable and everlasting trail. His training itinerary continues being a model to be followed by new generations of urologists as a complement to the MIR system.
