Scrotal trauma: a cause of testicular atrophy

Scrotal trauma is often mentioned as a cause of testicular atrophy yet ther e have been few studies documenting the effect of scrotal trauma on testicu lar size months or years following injury. We performed clinical and sonogr aphic examinations in 10 patients who had suffered blunt scrotal trauma, A significant reduction in volume of the injured testis was observed in 5/10 cases at follow-up sonography. In two cases the affected testis was heterog eneous and colour flow Doppler examination shelved reduced flow, In three c ases the testis was homogeneous but reduced in volume and in the remaining five cases the affected testis appeared normal. We conclude that testicular atrophy is a sequel of scrotal trauma and occurred in 50% of patients in t his study.
