title: A case of bilateral testicular calcifications in a bicycle motocross rider accompanied by bulbar urethral injury.
abstract: A 21-year-old Japanese man who was a professional bicycle motocross rider injured his perineum during a competition. Chief complaints were gross hematuria, perineal pain, and subcutaneous ecchymosis of the scrotum. Urethrocystography revealed a torn bulbar urethra and extravasation in the same region. Scrotal ultrasonography revealed small calcifications in the bilateral testes. Here, we report a case of bilateral testicular calcifications caused by the continuous shock and vibration of the saddle in an off-road bicycle rider.
