My youngest had this (both the hypospadias, and the chordee which is a bend in the penis). He had it repaired at 15 months, and the excess skin on the overside of his penis was used to create a new foreskin. Other than a post operative infection (which was pretty nasty, he ended up on IV antibiotics) he has had no issues. I am taking him to see a new surgeon next week though because he pees at a funny angle and I'm concerned the chordee is not fully repaired.

His penis looks completely normal though, and the scar is very faint and on the underside where it really can't be seen. He also has about twice the length he had before the op, which I'm sure he will be grateful for in about 15 years.
