376 Vasal Vessels Preserving Microsurgical Vasoepididymostomy

Vasoepididymostomy (VE) is becoming more and more popular in the developing countries in treating epididymal obstructive azoospermia. VE routinely ligated the vasal vessels to facilitated the anastomosis, according to the surgical anatomy, the vasal vessels preservation is obligatory in VE if the patient had received varicocelectomy especially non-microsurgical procedure previously to avoid postoperative atrophy and hydrocele. Furthermore, some patients who underwent VE may also be the future candidates of varicocelectomy or other kind of inguinal operation, We introduced the new technique of vasal vessels preserving VE and evaluate the impact of this technical modification on the surgical success. From May 2007 to May 2013, 80 patients had undergone microsurgical VE without preserving vasal vessels at the site of corpus or cauda. Between June 2013 and December 2014,VE with preservation of vasal vessels were performed in 33 patients at the site of corpus or cauda. Telephone follow-up had been carried out to retrospectively evaluate the surgical effect for all these 113 patients. The patency and pregnancy rate between two groups were compared.
