Diagnostic capabilities of high-resolution scrotal ultrasonography: prospective evaluation.

The use of scrotal ultrasonography has been advanced with the development of high-resolution real-time equipment. A group of 284 consecutive patients referred for scrotal examination was studied ultrasonically and followed over a three-year period. Abnormal scrotal contents were accurately detected in 98.5 per cent of cases. Separation of testicular from extratesticular pathology was 99 per cent accurate. While all malignant testicular lesions could be identified, there were examples which could not be differentiated from benign lesions prior to surgical exploration and biopsy. However, there are many examples where the ultrasound results can change clinical management of the patient.
