[Abstract]:Positive male, 26 years old, married for 2 years without birth. Body examination: bilateral testicular size is normal, scrotum segment vas deferens are not touched. Semen routine examination indicates azoospermia, sex hormone level detection is normal. Sonographic examination of scrotum showed that the size, shape and echo of bilateral testes were normal. The size of bilateral epididymis was normal and the echoes were not uniform, and some small cystic structures could be seen in it (Fig. 1). The vas deferens of the tail of epididymis and scrotum segment were not shown on both sides. The volume of bilateral epididymis was reduced with fine mesh-like changes. The distal end of epididymis was blind and showed "truncation sign" (Fig. 2). Transrectal ultrasound: left
