Hydrocele ,Hernia Hypospadias &

I live in north America. My 2 years old was just diagnosed with Hydrocele & Hernia
I requested to see a urologist since his right testicle was very very swollen.
I was told that a surgery is required and it will not pass by itself.

He was also diagnosed with Hypospadias Glanular- his urethral meatus is long and get t the glans.
I understand the Hypospadias is more cosmetic issue. What are the implications of this surgery? Is it better to do it now rather than wait and see when he will be bigger?


Thank you
