Angiography of the testicular artery as a diagnostic aid in boys with nonpalpable testis.

Selective angiography of the testicular artery was performed in 12 boys (age 3-14 yr) with nonpalpable testis. The angiographic, operative, and microscopic findings are described. True aplasia was diagnosed in seven patients. In three patients previously operated upon, the second exploration was facilitated by angiography. This method might be a valuable diagnostic aid in selected cases previously operated for gonadal disorders or inadequately explored for cryptorchism in order to avoid more extensive surgical exploration.
