Ultrasonography versus clinical examination in evaluation of testicular tumors

The diagnostic results of clinical examination and gray‐scale ultrasonography for scrotal pathology were compared in 411 patients. Sensitivity and specificity of the clinical diagnosis of a testis tumor improved significantly with the use of ultrasonography. Criteria for the ultrasonographic diagnosis of a testicular tumor were evaluated. We had no false‐negative ultrasonographic diagnoses, and they have rarely been reported in the literature. With ultrasonography, the number of false‐positive clinical diagnoses was reduced from 11 to 5. © 1994 John Wiley & Sons, Inc.
