Is it possible to get scar revision for suprapubic catheter scar?

I was diagnosed with female epispadias at the age of 2. Dozens of reconstrutive surgeries later and I am left with quite a few scars. The only one that bothers me is the very large indention left by the Suprapubic catheter that I had when i was 2. I am not over weight, college athlete and very healthy. But at the age of 20 this scar is becoming more and more indented. It seems to be attached to the underlying muscle. How difficult would it be to fix?
