I wouldnt re-apply if I were you. In a field like urology, I highly doubt the prestige of your school will play a major role in the match. What the poster above said is true, competitive step I grades, Honors and/or AOA, and good LORs will definately make you very competitive...however, the interview is a very important part of the urology match. They want people they can work with and they think will function as a team, this is of utmost importance in this field. In general if you are going to let something as trivial as the name of your school limit your chances you are already at a loss. Also, you are pretty early in your career to limit yourself to urology...it is a great field dont get me wrong but there are many other great fields out there as well. Just find what fits you and what you are going to like.
I go to a no-name state school that is pretty much under the radar nationally and several people in the years ahead of me have matched at extremely prestigious urology residencies.
good luck
