Most genitourinary surgeons advocate early exploration of all enlarging scrotal masses, hematoceles, or suspected testicular ruptures resulting from trauma. Two cases of torsion of the testicle following severe blunt testicular trauma are presented. It is suggested that another indication for prompt surgical exploration of a scrotal mass after severe blunt testicular trauma is to help establish an early diagnosis of torsion of the testicle. This approach affords an opportunity for appropriate therapy and testicular salvage.
