My kid had reconstruction on his penis. the opening was under instead of the tip. he has had the op but now that original opening has reopened. so now he is urinating for both opening. will the one that they patched close?

Can't say: This is a question you need to pose to the docs who know his case. The re-direction of the penile opening from hypospadias is complex & every case is unique. Have the kid evaluated by the team that did the work.

Fistula: Your description suggests that there is a fistula present. It is not likely to close on its own. Take your son to a pediatric urologist who can assess it and recommend the correct surgical treatment.
