title: Selective testicular venography for the localization of undescended testicles.
abstract: Percutaneous venography of the internal spermatic vein was performed for the localization of unpalpable testicles in 5 patients varying from 4 to 45 years of age. The catheterization of the vein on the left side was successful in all 5 cases; and the testicle was localized and verified by surgery in all but one case in which a competent valve prevented the retrograde filling of the whole length of the vein down to the testicle. In the two patients with bilateral undescended testicles the right internal vein could not be identified in one patient, and in the other patient a semiselective injection was done into that vein which appeared to represent the spermatic vein, but the examination was not conclusive.
