I am very interested in surgery, however, I have the world's smallest bladder. If I have to be in surgery for more than 4 hours, I think at some point, I will have to go pee. Do any of you have this problem? How will I pass my surgical rotation? Is there anything short of inserting a catheter that I could do? Can you just excuse yourself for a few minutes, take care of business, and then re-scrub?
