[Urological moulages: forgotten three-dimensional documents between university collections and panopticum -- a dying presentation form even in urological museology].

The use of wax models traces its roots back to antiquity and appears to have reached the peak of perfection in the eighteenth century especially in Italy. From the beginning of the nineteenth century wax models and moulages were used in the new medical specialties, such as dermatology or urology depending on a new model of visualization in natural sciences. The moulage passed from local use into international acceptance with the institutionalization of the medical specialties and increase in scientific communication in the second half of the nineteenth century. By the 1970s moulages had all but lost their pre-eminent position as teaching and visual aids to depict dermatological and venereal diseases Unfortunately urology was not mentioned in the field of history of medicine or ethnic studies.
