Abstract:
We report a case of bilateral synchronous testicular torsion in a newborn. A male neonate was referred one day after birth because his left testis was firm and enlarged. We found that the scrotum was firm bilaterally and suspected it to be bilateral testicular tumor. Surgical exploration which was performed at 2 days after birth revealed testicular torsion on both sides. Left orchiectomy, right detorsion biopsy and orchiopexy were performed. Histopathological examination confirmed hemorrhagic necrosis of bilateral testes.
