Abstract
An undescended abdominal testis has a high potential for the development of malignancy. Surgery may require both an inguinal and an abdominal exploration. We have used selective testicular venography in 7 men for preoperative testicular localization. In 5, the origin of the testicular vein was identified using this technique and the information acquired proved to be of considerable assistance to the surgeon. We recommend that this technique is used routinely in the localization of the impalpable undescended testis.
