Abstract
The site of obstruction was evaluated by seminal vesiculography in 24 cases of azoospermia with normal testicular biopsies. In 21 cases, obstruction was located at the level of the tail of the epididymis; in 2 cases ejaculatory duct was obstructed; and in 1 case the injected dye was arrested at the level of internal inguinal ring, at the site of previous hernia operation. Vesiculogram in 24 obstructed cases and 4 cases of chronic seminal vesiculities without obstruction showed one normal picture, four with catarrhal inflammation, and the rest with chronic interstitial vesiculities. Radiological study of a patient complaining of aspermia showed multiple congenital anomalies. The high incidence of chronic vesiculities and postinflammatory obstruction is attributed to underlying bilharziasis.
