Abstract

A retrospective study of seminal vesiculography (SVG) findings was undertaken in 62 patients with apparent obstructive azoospermia, both to evaluate the relative frequencies of various site of obstruction and the presence of other structural lesions and as an aid in planning possible surgical correction. Obstruction was found in 18 patients (29%). In 5 patients, the obstruction was located at the level of the ejaculatory duct, and in another 5, it was in the vas. In 8 patients, the sites of obstruction were different on the two sides. Four patients were found to have nonobstructing structural lessions.Surgical treatment of the obstruction found by SVG was possible in 12 patients (67% of those with documented obstruction). The SVG study is an excellent method of evaluating the male genital tract, not only for obstruction, but also for other structural lessions. Because different obstructive lesions were found on the two sides in 44% of the patients with documented obstruction, we strongly suggest that bilateral SVG be performed to aid in planning possible surgical correction of obstructive lesions.
