Microscopy has been and continues to be a major tool in the physician's diagnostic arsenal. Since its creation in 1595, the microscope has allowed for the close observation of small organisms, tissue samples and bacteria, since their discovery. Urologists use the microscopes to examine the urine, checking for absence or presence of red blood cells, white blood cells, casts and bacteria.
One of the most treasured collections in the Didusch Center is the Reuter Collection of microscopes, a donation from Hans Reuter in 1995. The collection ranges from single lens instruments to multi-lens varieties, and is displayed prominently in the library of the AUA headquarters.
