Epididymal Ultrasonographic Features of Moon et al Associated with Obstructive Azoospermia

 

The presence of one or more lesions in the epididymis was associated with obstructive azoospermia.

 

Findings seen in the head:

(1) tubular ectasia

(2) absence of head

(3) inflammatory mass-like lesion

 

Findings seen in the body:

(1) absence of the body

(2) tapering

(3) inflammatory mass-like lesion

 

Findings seen in the tail:

(1) absence of tail

(2) inflammatory mass-like lesion

 

Performance:

• The sensitivity was 82% and the specificity was 100%.

• The accuracy for identify obstructive azoospermia was 88%.

 

In addition, some of the patients with obstructive azoospermia had congenital bilateral absence of the vas deferentia (CBAVD).
