Impact of sonography on diagnosis of scrotal diseases: a multicenter study

Scrotal ultrasound was carried out since 1980 in five centers. 1,971 cases presenting with pathological conditions of scrotal content were reviewed to asses limitations and possibilities of the method. Scrotal sonography was found to be a highly reliable method to distinguish between intra- and extratesticular lesions. The data presented reveal that sonography is not capable of differentiating reliably between benign and malignant lesions. In the decision-making process ultrasound is sometimes of great help to the urologist but surely no substitution for careful examination and history taking.
