I have no idea, but if you don't like what you hear from a surgeon, get a 2d opinion from a better surgeon and see if the results are different. There are different ways to do surgery, and sometimes there are new ways an older surgeon decides not to learn how to do. Sometimes the surgery might be riskier than Google will tell you. Could be lots of things, so the only thing you can do is see ad different urologist and hope you get better info.
