ABSTRACT
This can occur when an anatomical anomaly allows the testis to twist, so compromising its blood supply. It occurs most commonly between the ages of 12 and 16 years, and presents with pain and swelling of the scrotum. A scrotal incision is made, the testis rotated, and then fixed to prevent recurrence. The anomaly predisposing to torsion is usually bilateral and the other testis may be fixed at the same time. It is a true emergency that must not be put off. Be prepared to interrupt a planned list if necessary.
