Repairing the hypospadias repair?

Couldn't find anything about this on UpToDate and I'm genuinely curious. I'm on my outpatient peds rotation right now and an 8 yo came in with leakage from a previously repaired hypospadias. Now I know hypospadias repairs use the foreskin, but what does Uro do for s/p circ hypospadias repair? Thanks! I'd love if there was an article/explanation!
