[The surgical exploration of the spermatic cord and testis with deferento-vesiculography (DVG) in the study of azoospermias (author's transl)].

The Authors refer about their investigation of the azoospermias with surgical exploration of the spermatic cord and testis with deferento-vesiculography (DVG). Thirty-three patients were examined with DVG from a total of 50 observations. The Authors conclude that such investigation, associated to the study of others parameters in the male sterility, reveals itself very useful to provide information about azoospermias. Therefore, while testicular biopsy informs on the histomorfologic aspect of the testis, the DVG provides the best investigation of the morphology of the seminal ducts.
