[Dr. Luis Cifuentes Delatte: clinician, surgeon and researcher].

The author, disciple of Dr. Cifuentes, thinks about the influence and teaching of his professor emphasizing some features that specially marked us. We emphasize his capacity to observe reality, his meticulous reading of all tests, his analysis of all the information obtained, and his intellectual rigor in the elaboration of the diagnosis. His interest for the patient, his thoughts about bladder cancer or the importance of statistics, and the introduction and support of endoscopic surgery in Spain are outstanding features. It is also outstanding his defense of urology as a medical-surgical specialty. As a conclusion we have his best legacy: his thoughts, his books and scientific works.
