[Alexis Boyer (1760-1833), eminent surgeon and anatomist and the study of urinary disorders].

Alexis Boyer, professor of clinical surgery at La Charité, first surgeon of Napoleon, baron of the Empire, left considerable written works covering the whole of external pathology. A great part of his works deals with urological affections, especially with micturition's disorders, in which one can appreciate the astonishingly high level of Boyer's knowledge on this matter, a knowledge which constitutes the germ of urodynamics.
