Eighteen patients who referred to our hospital with acute scrotal pain and swelling were evaluated with color-Doppler imaging (CDI) after the initial clinical examinations. Five of these subjects were considered to have testicular torsion as diagnosed with CDI. These diagnoses were surgically confirmed, and appropriate treatments were performed. CDI findings of 13 patients were in accordance with inflammatory pathologies (epididymitis and/or orchitis). These patients received medical treatment. The CDI diagnoses of all patients were in agreement with the final clinical diagnoses. We conclude that CDI, which is a practical, rapid and high-resolution technique, promises to be the leading and decisive scanning method in acute scrotal disorders.
