[Ultrasonographic investigations in diagnosis of congenital malformations of epididymis in cases of azoospermia].

Between 1984-1991 in 28 patients referred for the surgical treatment for the reason of obstruction of epididymis outlet ducts there was a suspicion of a congenital epididymis malformation put after the physical examination. The ultrasound examination of the scrotum which was performed in all cases revealed the proper view of the epididymis in 5 cases, the proper head of the epididymis with the broad tubules and the lack of the corpus and cauda in 19 cases and in 4 cases the residual head of the epididymis located in region of the upper pole of the testis. Intraoperative findings were consistent with the ultrasound results in 75.0% of cases. The highest consistency between the ultrasonographic and intraoperative findings was found in the cases with the proper view of the head of the epididymis with agenesis of corpus and cauda. In 32.1% of cases malformations of epididymis and vas deferens were associated with the malformations of the urinary tract.
