8) Flexibility within urology. The flip side to the issue of specialization is the fact that, within urology, there many, many facets. Some people decide to sub-specialize within oncology, or transplant, or infertility, or transplants, and some decide to be "general" urologists, with no specific sub-interest. For those who have thought about pediatrics, the decision to pursue a career in pediatric urology does not need to be made until late in residency. The same goes for other sub-specialties. Going into urology therefore allows a great deal of room to figure out what exactly it is that interests you, and you can chose late in residency (i.e. a good four or five years out of medical school) what kind of career you envision for yourself.
