[Calcification of vas deferens diagnosed by transrectal ultrasonography]

A 30-year-old male patient without diabetes mellitus and tuberculosis was referred to our outpatient department for the purpose of further examinations of azoospermia. Transrectal ultrasonography revealed the bilateral calcifications of vas deferens. Kidney-ureter-bladder X-ray and computerized tomography revealed also the same findings. Seminal vesiculography revealed no obstructive sign of vas deferens. Histopathology of testes showed hypoplasia. Judging from these findings, we diagnosed the case as calcification of vas deferens associated with spermatogenic disturbance. Review of the 31 cases reported in the Japanese literature including our case was performed.
