What is "vasography"

n. An invasive X-ray study of the vas deferens to check for blockage, often in the context of male infertility.

Vasography is an X-ray study of the vas deferens to see if there is blockage, oftentimes in the context of male infertility. An incision is made in the scrotum, contrast is injected in the vas deferens, and X-rays are taken from different angles. Thus, it is an invasive procedure and carries risk of iatrogenic scarring and obstruction of the vas. Vasography has traditionally been considered the gold standard imaging modality for evaluating the seminal tract patency.

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.
