[Experience with microsurgical epididymovasostomy (specific tubule technic: end-to-end anastomosis by the Silber...

Here, we report 2 cases of epididymovasostomy operation in which good results were obtained. These operations were done for patients whose complaints were male sterility due to obstructive azospermia after bilateral epididymitis. The method of this operation was reported by Silber in 1978 as "specific tubule technique", and excellent results have been reported. Herein, we introduce this technique perhaps for the first time in Japan, and the characteristics of this method are considered. The important factors and characteristics of this method are that it is very reasonable with a high success rate, it is more difficult than microsurgical vasovasostomy, it is a time-consuming operation. Epididymovasography should not be done preoperatively but intraoperatively, if possible and chronic epididymitis should be ruled out by serological study and culture study.
