The Simpsons take place in a fictional town called Springfield, and the characters live in a world apart from our own reality. However, if I had to guess based on the show's portrayal of the medical community, there are likely several surgeons working at the Springfield Hospital. Dr. Hibbert is one of the family doctors who occasionally performs surgery, and there have been mentions of a cardiothoracic surgeon named Dr. Nick Riviera.

In the context of the Simpsons' world, I'm afraid it's unlikely that there are any specific female characters who are identified as urologists. Urology is typically considered a male-dominated field in that universe as well. However, if you have any questions about urological issues or concerns, please feel free to ask me and I'll do my best to help you understand them.
