**Core Concept**
Phimosis is a condition where the prepuce (foreskin) cannot be fully retracted over the glans penis, often causing discomfort and urinary difficulties. The presentation of ballooning of the prepuce after micturition in a child suggests a condition known as paraphimosis, where the prepuce becomes constricted behind the glans penis due to prepucial adhesions.

**Why the Correct Answer is Right**
The best treatment for paraphimosis involves reducing the constricted prepuce to prevent tissue ischemia and gangrene. This can be achieved through manual reduction, where the constricted prepuce is gently pushed back over the glans penis. If manual reduction is unsuccessful, a dorsal slit or circumcision may be performed to prevent recurrence and associated complications. In this case, the child's prepucial adhesions need to be addressed to prevent paraphimosis.
