my nephew is 12 years old and still poops in his pants. where to initiate his treatment i.e. Gastronologist or pediyatric doctor.

Weakness; Loss of appetite; Stomach pain; Headache; Diarrhea or constipation; Cough.

At what age did you get this surgery done? It would be best for you to go for counseling with your urologist or sex specialist as people who undergo hypospadias have trouble with an active sex life and even masturbation.

in that case as mentioned above surgical treatment not required.
