Smith's General Urology is enough for MS3 rotation, but Urology Secrets covers stuff better. If you're going to buy one book, get Secrets then look other stuff up in Campbells or Smiths. Campbell's is on the core collection of MDConsult, if your school has that.
I'm an MSIII scheduled to start my Urology elective rotation at the end of this month. Does anyone know of any good resources/review books for a urology clerkship?
