anastomosis between the epididymis and the vas deferens?
vasoepididymostomy
vasoepididymostomy is often considered one of the most technically challenging operations in the field of urology. the procedure requires anastomosis of a single epididymal tubule (luminal diameter .15-.25 mm) to the lumen of the vas deferens (diameter .3-.4 mm), and is reserved for patients with congenital or acquired epididymal obstruction, or patients who have failed previous attempts at surgical reconstruction of the vas deferens. this surgery attaches the vas deferens directly to the epididymis, the coiled tube on the back of each testicle where sperm matures. a vasectomy can cause blockages or a break in the vas deferens or the epididymis. this surgery is used when a vasovasostomy won't work because sperm flow is blocked. the vas deferens is connected to the epididymis above the point of blockage.
vasoepididymostomy
bullet::::- type a: the supernumerary testicle is connected to a vas deferens. these testicles are usually reproductively functional. type a is further subdivided into:









































bullet::::- type a1: complete duplication of the testicle, epididymis and vas deferens.









































bullet::::- type a2: the supernumerary testicle has its own epididymis and shares a vas deferens.









































bullet::::- type a3: the supernumerary testicle shares the epididymis and the vas deferens of the other testicles.









































bullet::::- type b: the supernumerary testicle is not connected to a vas deferens and is therefore not reproductively functional. type b is further subdivided into:
polyorchidism
