in cases of bilateral non-palpable undescended testes in which human chorionic gonadotropin stimulation has shown the presence of testicular tissue and in cases of unilateral non-palpable undescended testes selective transfemoral gonadal venography with a modified seldinger technique has been used for the preoperative localization of the non-palpable testis . since the undescended testis may be located anywhere along the course of its embryologic descent , that is from the level of the renal fossa to its exit from the inguinal canal , preoperative localization will aid in the surgical management .
