Abstract
Postgraduate medical education is a major function of many medical centers today through the medium of short courses for practicing physicians in the various fields of medicine and surgery. The Editors of Postgraduate Medicine have arranged to publish recorded and edited selections from some of these courses to bring their information to a larger number of physicians than can attend the courses.
The first of these excerpts, from a continuation course in Urology for General Practitioners given at the University of Minnesota Medical School, is presented here. Other selections will appear in coming issues.
