Guyon

Guyon, Felix (Félix Guyon, 1831-1920), a renowned French urologist. He completed his medical studies at the faculty in Nantes, and from 1853 worked in Paris as an intern under Velpeau, under whose guidance he published two works: "Sur les cavites de l'uterus a l'etat de va-cuite" (P., 1858); "Des vices de conformation de 1 'uretre chez 1 'homme et les moyens d 'y remedier" (P., 1863). In 1867, following the death of Civiale, G. was put in charge of several beds at the Necker Hospital. In 1890, his department was expanded and transformed into a urological clinic, which he headed until 1906. G. was for a long time the chairman of the French Surgical Society, the French Society of Urologists, the International Urological Association, the Medical Academy, surgical and urological congresses, and an honorary member of a number of French and foreign medical societies. The greater part of G.'s activity took place at a time when the methodology for examining the urinary tract was in its infancy, when cystoscopy was not a common research method, and when catheterization of the ureters did not exist, and this circumstance should explain the fact that the greater part of G.'s works concerns diseases of the lower part of the urinary sphere. Part of G.'s works has not lost its significance to this day, despite their antiquity. His three-volume work "Legons cliniques sur les maladies des voies urinaires professees a l'hopital Necker" (P., 1881; Russian ed.-SPB, 1899) is widely known. To G.'s credit should also be counted his pedagogical activity, which manifested itself in attracting a significant number of students who later became no less famous than their teacher (Albarran, Janet, Motz, Legue, Desno). G. became most famous for the diagnosis and treatment of bladder stones and urethral strictures (see Bougies).
