Microsurgical epididymovasostomy.
Epididymal obstruction is found in about 30% of obstructive azoospermic patients. Half of these obstructions are due to unknown etiologies, followed by obstruction due to epididymitis. The development of a specific, mucosa-to-mucosa anastomosis of the epididymal tubule to the vasal mucosa using a surgical microscopy has greatly improved the outcome of epididymovasostomy. The patency and natural pregnancy rates in this study were 79% and 38%, respectively. Side-to-end anastomosis also decreases the technical difficulty in comparison to the end-to-end anastomosis procedure. An anastomosis at the epididymal caput generally results in a poorer outcome than at the corpus or cauda epididymis.
