In children you don't "repair" the hernia in the same sense as in adults. The only one thing to be done is just to free the sac and put it back to the abdominal cavity, for the defect is a persistent peritoneo-vaginal duct. There's not tissues damage, unless you find no posterior wall or a very big deep inguinal ring, rare situations. Why to "repair" it in older children or young adults?, because there already exists tissue damage, in other words, or the inguinal ring is wide in the indirect hernia or the posterior wall is weak in the direct ones. The use of meshs is still controversial. I prefer the use of methods without meshs, especially in young people. Nobody knows what happens in the long term with the function of the vas deferens in contact with foreign materials. I think that it should be preferable to do a second operation if a recurrence occurs, instead of putting a mesh in a young man in the first op. Shouldice method shows the same recurrence rate of the methods with the use of meshs, so it is a very good option.
