Boat,
Welcome. I am not familiar with either hospital so maybe someone else will comment. Whoever does the procedure... make sure they are doing at least 25-35 of these a year. This is so much more and different than the prostatic cancer that most see the most of. I am also linking a good summary of the 3 different diversions that may put to rest any questions:

Keep posting as you have questions, some one will respond.
