[Traumatic dislocation of the testis].

Dislocation of the testis is a rare injury, with only 73 cases having been reported in Japan. We herein add 6 cases. Lately, accidents involving teenage patients, primarily involving motorcycles, have been increasing. Closed reduction is recommended, but it was successful only 5 of 73 cases. The results of testicular biopsies suggest that early surgical management is required when closed reduction is unsuccessful.
