Testicular torsion in children--bilateral or unilateral operation.

Between 1969 and 1984 65 children were operated on for testicular torsion. A follow-up study of 63 patients who underwent surgery for unilateral testicular torsion with fixation only on the affected side showed that no torsion occurred on the opposite nonfixated side and there was no retorsion during an observation period of an average of more than seven years. From our calculated risk for contralateral testicular torsion we suggest that bilateral fixation is not necessary in children who present with a unilateral testicular torsion.
