[Three cases of vas deferens calcification]

Three patients with calcification of the bilateral vas deferens, revealed by plain X-ray, pelvic computerized tomography and/or vesiculography, are reported. Although they came to our department because of acute left epididymitis, right ureteral calculus and right undescended testis respectively, these diseases were not the causative factors for the calcification. Since no other probable causes including tuberculosis and diabetes-mellitus were found, the cause of disease was unknown.
