Yes, I have to say, from reading your comments over the past year, I am not surprised you would be interested in Urology.
Having said that, why just stop at the "prestigious" specialties, go all out and hit up the "prestigious" residencies for these "prestigious" specialties.
I must note though, unless you are attending a "prestigious" medical school with a "prestigious" home program, you will have an uphill battle. There are number of steps you could follow though:
1) Get a Step 1 score in the "prestigious" level. Remember, just like the MCAT, the Boards are BY FAR the most important things....like 75+% of your application.
2) Don't stop with doing research...heck don't stop at just getting first author publications. You need to get first author publications in the "prestigious" journal. Check out IF and sort out the "prestigious" journals, and shoot only for these journals.
3) ONLY rotate at "prestigious" programs. Again, the "prestige" is important here. You want letter from "prestigious" chairmen and surgeons.
Follow the "prestige" everywhere and anywhere you go, it is the key to life. "Prestigious" residency = "prestigious" job = "prestigious" babes (or dudes, don't know your sexual preferences?...actually the urology bit might lead your more to the latter the more I think of it...)
