Torsion of the testis is a surgical emergency. Although it occurs in all age groups, torsion is most common in adolescents.
The typical presentation is with a tender, swollen scrotum and lower abdominal pain; symptoms are however variable and often much less marked in young children and neonates.
The incidence of torsion is higher for undescended testes.
The scrotum must be explored surgically if there is any uncertainty about the diagnosis.
