Microscopical splint epididymovasostomy.
Splint epididymovasostomy is a new approach in operative andrology. In 23 rats, a microscopical splint epididymovasostomy was done in two groups 40 days after sterilization using 5/0 polyglactic acid and 5/0 plain-catgut as a splint. 28 anastomoses could be evaluated. 3 months later, in 2 of the 16 animals (12.5%), spermatozoa were detected in the ejaculate after electro-ejaculation. In six of the specimens (27.3%), the methylene blue given from the vas deferens passed into the epididymis. The patency of these was also proved histopathologically. The catgut splints were absorbed within 3 months. Microscopical splint epididymovasostomy shows that this method can lead to a free passage of the spermatozoa.
