Did they tell you where they were going to make the incision? I had a 3 inch incision that was immediately to the left of my belly button with two port holes to the side. The surgeon told me the position of this incision cuts through less muscle. Instead, it cuts through the tough fascia tissue. As a result, he said that while it would never be 100% like uncut tissue, within 6 months I could expect that it would be about 80% as strong as if it were uncut. They used a tool with a mesh bag on the end to "capture" the kidney, once it was removed, and pull it out through that incision. I am not sure my recovery was any different than any other lap type nephrectomy. I will tell you that now, five years out, unless you were really looking for them, you can hardly see either the incision or port holes.
It's kind of interesting that, if you took a poll, you would find everyone's incision all over the board. Guess all surgeons have their favorite!
