Vasography is an X-ray study of the vas deferens to see if there is blockage, oftentimes in the context of male infertility.[1] An incision is made in the scrotum, contrast is injected in the vas deferens, and X-rays are taken from different angles.[1] Thus, it is an invasive procedure and carries risk of iatrogenic scarring and obstruction of the vas.[2] Vasography has traditionally been considered the gold standard imaging modality for evaluating the seminal tract patency.[3]
To avoid performing an extra operation, vasography is encouraged to be done at the time of correction of the obstruction, and thus should not be done as an isolated outpatient procedure.[2]
