Hi Laura... You can start by checking the annual U.S. News rankings of the top hospitals here:
Top Hospitals 2015-2016
You can click on various specialties for rankings in that category. There is a link for Urology.
You can also search for Doctors by location or name. It generally gives how long they have been in practice and any hospital affiliations. That link is:
Search for Doctors
After you narrow down a hospital that you may want to go to for treatment, go to their website and find the urology department. Many hospitals publish the CVs of their physicians. After choosing a physician, make your appointment and during your appointment, ask about his experience level with RCs. A professional and qualified doctor should not hesitate to readily provide this information to patients.
It can be a frustrating process. Good luck and I'm sure your dilligence and perseverance will pay off.
