Epididymovasostomy is a more complex version of the Vasovasostomy. This procedure is chosen if the blockage of sperm is at the level of the Epididymis. This procedure is one of the most complex microsurgical procedures performed.
This technique involves placing two or three sutures in the distended epididymal tubule and then connecting them to the vas deferens before opening the tubule. This makes the procedure significantly easier as the surgeon can place the sutures in the enlarged distended tubule rather than the open deflated tubule. Once all the sutures are placed, the tubule is opened with a microsurgical knife and the sutures are sequentially tied down.
