A. VAS DEFERENS, LEFT, VASECTOMY: | |||
- VAS DEFERENS WITHIN NORMAL LIMITS, LOOP OF EPITHELIUM AND MUSCLE LAYERS PRESENT. | |||
B. VAS DEFERENS, RIGHT, VASECTOMY: | |||
- COMPATIBLE WITH VAS DEFERENS, WITHOUT COMPLETE LOOP OF EPITHELIUM, SEE COMMENT. | |||
COMMENT - PART B: | |||
Definite vas deferens epithelium is not identified; however, the muscle layering seen is | |||
compatible with a vas deferens. Levels were cut (x4). | |||
Clinical correlation is suggested. | |||

====No vas deferens identified==== | |||
