7) Specialization. Specializing in urology means knowing one field--one body system--inside and out. You are the expert on all things urologic, but relatively useless when it comes to other parts of medicine. Thus, one of the draws of urology for many is the opportunity to take a very focused part of medicine and be an expert in that area. Many internists feel uncomfortable dealing with urologic issues, thus almost everything in the urologic arena gets sent to the urologist. Specialization is an important issue in and of itself, and may not be the right choice for people with a "jack of all trades" mentality.
