[A case of bilateral testicular torsion in a neonate].

A case of testicular torsion in the newborn is presented. A 8-day-old infant with bilateral intrascrotal swelling since birth was referred to us. Bilateral testicular torsion was suspected and operation was carried out at the same day. We operatively found extravaginal torsion of the bilateral spermatic cord. The bilateral testis appeared extensively necrotic, but we repaired the torsion and performed bilateral orchiopexy because of bilateral torsion. We could not palpate well the bilateral testis in one year, probably due to an atrophy. Sixty-nine cases of testicular torsion in the newborn including our case from Japanese literatures were reviewed and discussed. Especially forty-seven cases were presented at birth.
